Customer Needs and SKF Offer

Needs:

• Save total cost (OEM)

• improved value offer for endusers (OEM)

• Keep life cycle cost low(less maintenance) (EU)

Offer:

• Simplifies mounting

• Simplifies lubrication

2008-05-06 ©SKF Slide 7 [Code] SKF [Organisation]

Offer

Features

Integrated customized sealings engineered for longtime grease lubrication

Grease selection to meet longtime grease lubrication

Function

Proper sealing function

Avoid contamination to enter bearing

Avoid grease leakage

2008-05-06 ©SKF Slide 8 [Code] SKF [Organisation]

Offer

Benefits

milestone to achieve "oil-free press"

longtime grease lubrication possible

simplification of central lubrication system possible (pump, pipes, filters)

grease provides longer lifetimes than oil (oil needs to be changed frequently)

grease, seal- and bearing design dimensioned for long-time grease lubrication

optimized engineering/design

less re-greasing less maintenance activities

2008-05-06 ©SKF Slide 9 [Code] SKF [Organisation]

Offer

Benefits (continued)

SKF competence in bearings, seals, lubrication, lubrication system bundled

less single components, one supplier for whole system, easier logistics

no oil leakages no pollution of print medium, clean machine operating reliable

decrease total cost

improved value offer for endusers

keep life cycle cost low

Offer

Features

Integrated customized tapered sleeve engineered and manufactured for easy mounting

Function

By moving the tapered sleeve in axial direction onto the tapered seating the outer diameter expands

Thus eliminates the initial clearance between sleeve and side frame bore

Tight fit between bearing system and side frame will be achieved

2008-05-06 ©SKF Slide 11 [Code] SKF [Organisation]

Offer

Benefits

no selective choice bearing outer diameter with side frame bore necessary anymore

each individual bearing fits to each individual side frame bore

in case of bearing replacements interchangeability is given

simplified machining of side frame bore

in case of intended tight fit between OD and side frame no cooling of bearing necessary anymore

2008-05-06 ©SKF Slide 12 [Code] SKF [Organisation]

Offer

Benefits (continued)

guaranteed tight fit easy to achieve

less mounting time

easier logistics

decrease total cost

Offer

Features

Integrated customized short taper joint engineered and manufactured for easy mounting

Function

Enable connection to printing cylinder

2008-05-06 ©SKF Slide 14 [Code] SKF [Organisation]

Offer

Benefits

Easy and time saving connection to printing cylinder, less mounting and dismounting time

Less time consuming when changing printing cylinders

Bearing system fully interchangeable

No preassembly of inner ring onto tapered shaft seating necessary anymore

2008-05-06 ©SKF Slide 15 [Code] SKF [Organisation]

Offer

Benefits

Defining of radial clearance/preload during preassembly not necessary anymore (is done by SKF)

easier logistics

decrease total cost
