SKF Food Line Y-bearing units

From the acidity of citrus products to the

abrasiveness of bakery goods, food and

beverage equipment is impacted by both the

characteristics of the products being made,

and the cleaning requirements of the manu-

facturing environment.

To prevent bacterial growth, machineryis exposed to frequent high-pressure wash-

downs with caustic antibacterial cleansing

agents.

This process adds water and cleaning

solutions to the list of contaminants that

cause corrosion and accelerate bearing

failure. Because the washdowns can also

wash lubricant out of the bearing cavity,

frequent bearing relubrication is necessary.

Environmental concerns related to lubricants

and contaminants entering the waste stream

must be addressed, adding to the total cost

of operations.

High-performance insertbearings

Strong and corrosion-resistant

At the heart of the SKF Food Line Y-bearing

unit is a high-quality, corrosion-resistant

insert bearing, with bearing rings and balls

available in two executions:

Stainless steel grade 420, rings and balls•

Zinc coated high grade carbon chromium•

rings and high grade carbon chromium

balls

Both are equipped with the same high

performance sealing system († fig. 1,

page 4).

Designed for extended service life

Each of the SKF Food Line Y-bearing types

is designed to be self-aligning to provide

longer bearing service life. To accommodate

misalignment, the concave bore of the

housing is designed to accommodate the

convex outside diameter of the bearing.

This arrangement minimizes internal loadsacting on the bearings that could result from

installation errors.

The bearing inner ring is extended on both

sides and is locked on the shaft with stain-

less steel grub screws that are positioned

at 120°, minimizing inner ring distortion

while maintaining good gripping strength.

Extended service life is achieved as a re-

sult of the effective sealing system, which is

made of FDA approved materials and uses

NSF approved food grade grease.

Innovative and effectivesealing system

Prevents contamination, retains

lubrication

All SKF Food Line Y-bearing units incorpo-

rate SKF’s unique “-2RF” multiple seals,

which keep detergent, water and other con-

taminants out of the bearing cavity whilekeeping lubricant inside.

Multiple barrier protection provides long

bearing service life

The SKF seal arrangement is proven to be

highly effective during washdowns. It con-

sists of a multi-lip contacting and labyrinth

seal supported by a stainless steel insert,

a stainless steel flinger with a vulcanized

rubber lip, and a rubber-backed gasket seal

(† fig. 1).

The flinger adds mechanical and centrifugal1

protection against contaminants entering

the bearing cavity, and provides a first

contacting seal with its rubberized lip

acting axially against the gasket seal.

The space between the flinger rubberized2

lip and the gasket seal is filled with SKF

food grade grease in order to provide

additional protection.

Additional sealing efficiency is achieved3

through the labyrinths created by the

flinger's external diameter and the outer

ring, plus the metallic seal insert and theinner ring shoulder.

Food compatible materials

The flinger and the seal’s contacting lips•

are made of an FDA approved rubber

compound.

The space between the insert seal and•

the flinger is filled with SKF food-grade

NSF approved grease.

Chemical resistanceSKF Food Line Y-bearing units resist a wide

range of chemicals and other treatments

used during the washdown process

End covers

Secure fit, operator safety

If needed to comply with health and safety

regulations, composite, stainless steel and

cast iron zinc coated SKF Food Line Y-bear-

ing units can be supplied with effective end

covers. Two different cover designs are

available:

ECW (• † fig. 2) for composite, cast iron

zinc-coated and stainless steel SKF Food

Line Y-bearing units

ECL (• † fig. 3) for some of the composite

SKF Food Line Y-bearing units identified

by the suffix L in the designations.

The appropriate end cover for each SKF

Food Line Y-bearing unit is listed in the

product tables. Note that the end covers are

not included with the Y-bearing units andmust be ordered separately.

The ECW cover has an optional drainage

hole that can be easily opened by the user

as required.

For complete security, both ECW and ECL

end covers are tested to withstand 100 bar

pressure wash and will not dislocate during

washing,

High-quality, NSF H1approved grease

Each SKF Food Line Y-bearing unit is pre-

lubricated for life with a non-toxic food-

grade grease, based on a PAO oil which

contains an aluminium-complex soap as

thickener (food industry approved NSF H1).

This high quality synthetic grease isodourless and tasteless, leaving food

unaffected.

Broad temperature range

Approved for use in all food and beverage

processing equipment, SKF food-grade

grease has a temperature range from

–45 to 150 °C. († diagram 1)

Extends bearing life

SKF food-grade grease offers advantages

that help extend bearing life, including:

Excellent internal and external bearing•

corrosion protection

High aging resistance for extended lubri-•

cant life

Unreliable performance (use only for short periods)

Reliable performance, i.e. with predictable grease life

1) Despite grease suppliers indicating the specificvalues for the low and high temperature limitsin their product information, SKF recommendsusing these low/high temperature performance

limits for reliable bearing operation.

It is within these two limits, the greenzone in diagram 1, where the grease will

function reliably and grease life can be

determined accurately.

At temperatures above the high tempera-

ture performance limit (HTPL), grease will

age and oxidize with increasing rapidity and

the by-products of the oxidation will have a

detrimental effect on lubrication. Therefore,

temperatures in the amber zone, between

the high temperature performance limit and

the high temperature limit (HTL), should

occur only for very short periods.

At temperatures below the low tempera-ture performance limit (LTPL), the tendency

of grease to bleed decreases and the stiff-

ness (consistency) of the grease increases.

This will ultimately lead to an insufficient

supply of lubricant to the contact surfaces

of the rolling elements and raceways. Since

ball bearings are easier to lubricate than

roller bearings, the low temperature per-

formance limit is less important for ball

bearings. Short periods in this zone, e.g.

during a cold start, are not harmful since the

heat caused by friction will bring the bearingtemperature into the green zone.

Temperature [°C ]

The SKF traffic light concept

Based on the exclusive SKF traffic light con-

cept, the temperature range over which the

grease lubricating the SKF Food Line Y-

bearing units can be used is defined by four

temperature limits schematically illustrated

in diagram 1 in the form of a “double traffic

light”.

The definitions of the extreme tempera-

ture limits are the following:

The low temperature limit (LTL), is the•

lowest temperature at which the grease

will enable the bearing to be started upwithout difficulty.

The high temperature limit (HTL) is given•

by the grease dropping point. The drop-

ping point indicates the temperature at

which the grease loses its consistency and

becomes a fluid.

Operation at temperatures below the low

temperature limit and above the high tem-

perature limit is not advised as shown in

diagram 1 by the red zones1).

The recommended temperatures forreliable bearing operation are given by the

following SKF values:

The low temperature performance limit•

(LTPL).

The high temperature performance limit•

(HTPL).

SKF Food LineY-bearing units requireno relubrication

No relubrication meansreduced environmental impact

Less wasteThe cycle of washdowns and lubricant

washout in food and beverage manufactur-

ing creates a never-ending cycle of waste.

It is common to relubricate bearings after

each washdown – daily, weekly or at other

intervals based on production specifics.

During this process, excess grease is dis-

charged past the bearing seals (purged).

At the next washdown cycle, the grease is

washed away and into the plant’s waste

water.

Because they can withstand frequentwashdowns without relubrication, greased-

for-life SKF Food Line Y-bearing units elimi-

nate the need for relubrication, grease dis-

posal and concern about environmental

impact († fig. 4).

Reduced grease consumptionAs an example, relubricating 100 bearing

positions require about († fig. 5):

15 g (0.53 oz.) of lubricant per bearing

purge, which equals1,5 kg (3.3 lbs.) per weekly maintenance

cycle, or a total of

78 kg (172 lbs.) of lubricant per year

With the SKF Documented Solution Pro-

gram, your SKF representative can show

you how much you can reduce cost with SKF

Food Line Y-bearing units, based on running

data from your own plant.

Housing materials

Composite housing

Strong, lightweight, chemical resistant

Capable of resisting citric acids, cooking fats

and most food and beverage processing

chemicals, the composite housing of SKF

Food Line Y-bearing units is constructed ofa thermoplastic composite material that is

significantly lighter than cast iron housings.

The housing’s spherical bore accommodates

the insert bearing’s spherical outer surface,

enabling the unit to fully compensate for

initial bearing seating misalignment.

Other performance advantages include:

F• racture strength – Steel coils embed-

ded in the housing1) or dedicated rugged

design2) contribute to its fracture strength.

Radial breaking load is far greater thanthe static load rating of the bearing. The

SKF Food Line Y-bearing unit is estimated

to have the highest fracture strength of

any composite unit on the market.

F• lush mounting – A polyamide filled

housing base or a solid base allow the

units to meet flush with its mounting sur-

face. This surface-to-surface mounting

eliminates gaps where contaminants

could potentially collect.

S• tability – Stainless steel bolt-hole inserts

provide added strength and stability to

each housing foot to prevent corrosion.

Stainless steel housing

Extreme strength and toughness

For extremely challenging food and bever-

age applications requiring ultimate durability

and chemical resistance, housings cast from

AISI 300 series stainless steel may be the

best answer.

Strength – SKF Food Line stainless steelY-bearing housings are designed for appli-

cations where very heavy loads or shock

loads are possible.

Safety – In applications where housing

failure could result in injury, the safety factor

inherent in cast steel is an advantage.

Chemical resistance – Compared to

composite and zinc coated cast iron hous-

ings, cast stainless steel offers a higher level

of resistance to aggressive washdown

chemicals. Cast stainless housings are not

affected by strong concentrations of chlo-rine, hydrogen peroxide or other chemicals.

Surface finish – The finish of SKF cast

stainless steel housings prevents material

from becoming trapped on housing surfac-

es. The bases are cast flat with no recesses

to trap debris and bacteria, and the exposed

surfaces have no unnecessary crevices or

Coated cast iron housing

Strong and corrosion resistant

Strength, durability and long-term corrosion

resistance make SKF coated cast iron hous-

ings an ideal choice for red meat, pork and

poultry processing applications.

The heavy-duty cast iron is protected with

a CrVl-free zinc coating on all housing sur-

faces for long-term corrosion resistance. The

zinc coating eliminates the flaking problemsassociated with nickel plated products.

Chemical resistance – These zinc coated

bearings are resistant to the majority of

common washdown solutions.

Mounting instructions

General

To provide proper bearing performance and

prevent premature failure, skill and cleanli-

ness are necessary when mounting SKF

Food Line Y-bearings or Y-bearing units.

As precision components, they should be

handled carefully when mounting. It is also

important to choose the appropriate method

of mounting and to use the correct tools.

The method used for mounting a SKF FoodLine Y-bearing unit depends on the:

overall machine design•

Y-bearing housing design•

method used to attach the unit to the•

shaft

NOTE: Failure to carefully follow applicable

mounting instructions can result in prema-

ture bearing failure or improper perform-

ance. For further information, contact the

SKF application engineering service. De-

tailed mounting instructions can be foundon the following pages. SKF Food Line Y-

bearings, Y-housings or Y-bearing units

should not be removed from their original

packaging until immediately before they are

mounted.

ToolsTo mount or dismount SKF Food Line

Y-bearing units, the following tools are

required:

a hexagonal key (hex wrench) to tighten•

or loosen grub (set) screws

a spanner or hexagonal key to tighten•

or loosen the fasteners.

Attaching SKF Food LineY-bearing units to thesupport base

To reduce vibration and enable heat to

dissipate from the unit, the housing must

be firmly attached to the support base. To

attach SKF Food Line Y-bearing units to the

support surface, SKF recommends using

8.8 class bolts or studs and a washer to

ISO 7089:2000 or 7090:2000 and a springwasher. Hexagonal head bolts in accordance

with ISO 4014:1999 are appropriate. Alter-

natively, hexagonal socket head cap screws

in accordance with ISO 4762:1988 can be

used († fig. 1).

Shaft tolerancesThe recommended fits for SKF Food Line Y-

bearings are listed in table 1. For moderate

loads (0,035 C < P ≤ 0,05 C), the shaft seats

should be machined to an h7 tolerance. For

light loads and low speeds, an h8 shaft tol-

erance is sufficient and for very simple ap-

plications, h9 to h11 shaft tolerances may

be used. Fig. 2 illustrates the location of the

most commonly used ISO shaft tolerance

grades. The values of these ISO tolerancesare listed in table 2 on page 13.

Limiting speedsThe limiting speeds of SKF Food Line Y-

bearings and SKF Food Line Y-bearing units

are shown in the product tables. The values

refer to shafts with tolerances up to h7 or

more. In cases with shaft tolerances of h8,

h9 and h11, the limiting speeds must be

reduced according to the values listed in

table 3.

Assembling unitsIn cases where the SKF Food Line Y-bear-

ings and Y-housings are not supplied as a

unit, the first step is to assemble the bearing

into the housing. Start by inserting the

bearing into the filling slot in the housing

bore († fig. 3). Then, with a round piece of

wood or pipe, swivel the bearing into posi-

tion so that the grub screws are facing in the

When installing SKF Food Line Y-bearings,

make sure that the relubrication features in

the outer ring holes or relubrication grooves

do not coincide with the filling slot in the

housing, otherwise grease leakage may

result.

If you need to re-assemble a unit type

that can be relubricated, make sure that therelubrication features in the outer ring holes

or relubrication grooves coincide with the

relubrication facility in the housing.

Mounting instructions forSKF Food Line Y-bearing units

Remove any burrs on the shaft with emery1

cloth or a fine file, wipe clean with a cloth.

Depending on loads and speeds, define

the appropriate shaft tolerance from

table 2, page 13, and check the shaft

diameter.Mount any components that are on the2

shaft between the two SKF Food Line

Y-bearing units.

Make sure the housing base and mating3

surfaces are clean and free of any debris

or burrs. Ensure the supporting surface is

flat .The flatness should be within the IT7

tolerance grade and that the roughness

Ra ≤ 12,5 mm. If the housing requires

shims or adjustment, the shims must ex-

tend the full length and width of the base.

Slide the4 SKF Food Line Y-bearing unit

onto the shaft with grub screws facing

outwards. For pillow block units, fit the

attachment bolts or nuts but do not tight-

en them. For flanged units, fasten them

securely to the machine wall.

Mount the other5 SKF Food Line Y-bearing

unit on the other end of the shaft.

Carefully align both6 SKF Food Line Y-bearing units, using the shaft. For pillow

block housings, fully tighten the attach-

ment bolts or nuts for all units. For flanged

housings, securely fasten the second unit

to the machine wall.

Align the shaft in the bearing arrangement7

axially and – if possible – turn it a few times.

Tighten the grub screws in the inner rings8

of both units to the tightening torque in-

dicated in table 4.

If applicable, snap the end cover(s) into9

place.

End coversThe product tables show the appropriate

end cover for each bearing unit, and the dis-

tance (A5) that the end cover protrudes

from the housing side († fig 6). Prior to

starting the mounting procedure, make sure

to use the correct end cover and check if the

A5 dimension is suitable for your application

arrangement.

NOTE: the end cover must be orderedseparately.

Mounting instructions for end covers

Remove the end cover from its package.1

Identify the housing end cover groove and2

make sure it is clean and free of any

debris.

Hold the cover askew against the housing3

and insert the cover tabs into the housing

groove. Note that in composite housings

with suffix Y in the designation, the end

cover groove does not cover the wholecircumference, which is interrupted in the

insert slot area.

Push the cover towards the housing until4

all the tabs snap into the housing groove.

Where needed, help the tabs into position

by bending the cover edge slightly as

required.

Make sure5 the cover is securely in place.

If needed, remove the end cap and start

the process again from step 3.

Dismounting instructions for end covers

Insert a screwdriver or a pointed tool into1

the space between the Y-housing and the
