5.2 Lubricant selection/lubricant table

5.2.1 General information on selecting the oilUnless a special arrangement is made, SEW-EURODRIVE delivers the drives withoutoil fill. This does not apply to auxiliary drives and primary gear units.

The following tables provide an overview of mineral and synthetic oils.

Mineral oilStandards Lubrication oils are divided into ISO VG viscosity classes according to ISO 3448 and

DIN 51519.

Synthetic oilStandards Lubrication oils are divided into ISO VG viscosity classes according to ISO 3448 and

DIN 51519.

INFORMATIONThe oil viscosity and type (mineral/synthetic) to be used are determined by SEW-EURODRIVE specifically for each order. This information is noted in the orderconfirmation and on the gear unit's nameplate. Any deviation from these conditionsrequires consultation with SEW-EURODRIVE.

INFORMATIONThis means the gear unit must be filled with the correct oil grade and quantity beforestartup. You find the corresponding information on the nameplate of the gear unit.

5 Lubricant selection/lubricant tableLubrication, Cooling and Heating

In addition to the required viscosity, the oil must fulfill the following criteria:• CLP oils according to DIN 51517-3• Micro-pitting test according to FVA, FV no. 54/ I-IV, GFT class high, damage force

level >10

If synthetic oil is used, SEW-EURODRIVE recommends polyalphaolefin-based oil(CLP HC).

5.2.2 Permitted lubricants

Key to the lubricant tableThe lubricant table shows the permitted lubricants for SEW-EURODRIVE gear units.Please note the abbreviations, meaning of shading and notes.

INFORMATIONObserve the operating temperature of the gear unit when specifying the oil changeintervals.If required, a cooling system must be used or the oil change interval must be shortened(see "Lubricant Change Intervals" in the "Helical and Bevel-Helical X.. Series GearUnits operating instructions).

INFORMATION• The standard for viscosity and oil grade is the type of oil that is specified by SEW-

EURODRIVE in the order (see order confirmation and nameplate).• Consult SEW-EURODRIVE if you use bio and food grade lubricants or polyglycol

oils.• Check the compatibility of the greases and oils used.

CLP = Mineral oilCLP HC = Synthetic polyalphaolefinE = Ester oil (water hazard classification 1)

= Mineral lubricant = Synthetic lubricant

3) = Use lubricants only when service factor Fs ≥ 1.34) = Take into account critical startup behavior at low ambient temperatures6) = Ambient temperature

= Lubricant for the food industry (food grade oil)

= Biodegradable oil (lubricant for agriculture, forestry, and water management)OilOil

5.4.6 Circulation cooling – Oil-water cooler with motor pump for pressure lubrication /OWPAn oil-water cooler can be used if the thermal rating of the naturally cooled gear unit orcooling using a fan on the input shaft is not sufficient. The prerequisite for using an oil-water cooler is that appropriate cooling water is available on site.

Structure

The cooling system is delivered as a complete unit but without electrical connections.The standard design of the basic cooling system comprises:• Pump with directly mounted asynchronous motor (pump and cooler permanently

running)• Oil-water heat exchanger• Oil filter with filter element and electrical/optical contamination indicator• Pressure switch that monitors the pump pressure. Warning or switch-off signal when

the oil pressure reaches < 0.5 bar• Temperature switch with trip point for monitoring the cooling group, i.e. warning or

gear unit shutdown when the oil temperature reaches > 90 °C

INFORMATION• Consult SEW-EURODRIVE if you use chemically aggressive cooling media, such

as brackish water or salt water.• The cooling system with motor pump cools the gear unit oil and the pressure

lubrication of the gear unit.• When installing a filter in the OWP cooling system, make sure there is sufficient

height for removing the filter element and the filter hood.

INFORMATION• It is essential that the heating elements are fully immersed in the oil sump to

prevent any damage.• The position of the thermostat and the temperature sensor varies with design and

mounting position of the gear unit.• Not all combinations of accessory options might be possible depending on the

mounting position and mounting surface. Consult SEW-EURODRIVE

INFORMATIONFor dimensions of the oil heater, see page 437.

5.5.2 Notes on the function of the oil heater• The switching point of the oil heater thermostat is factory set to a temperature of

about 5 K above the respective limit temperature "without heater". The thermostatturns off the oil heater at this temperature. Only then, the gear unit may be startedup. If the temperature falls below the trip point by approx. 5 K, the thermostatactivates the oil heater again.

• Thermostat and oil heater are installed on the gear unit and are ready for operation,but they must be wired properly and connected to the external power supply beforestartup.

• Contact SEW-EURODRIVE if another oil viscosity class is used or if ambienttemperatures fall below the specified limit temperature.
