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

5.5.2 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.

INFORMATIONThe temperatures specified refer to the average values of the permitted lubricantsbased on the lubricant table (see page 73). In borderline cases, the permittedtemperature of the lubricant that is actually being used must be verified. Whenplanning the motor, observe the increased starting torque at low temperatures. It maybe necessary to contact SEW-EURODRIVE.
