General
information
Unless a special arrangement is made, SEW-EURODRIVE supplies the drives with a
lubricant fill adapted for the specific gear unit and mounting position. The decisive factor
is the mounting position (M1 – M6, → Sec. "Mounting positions and important order
information" in the Gearmotor catalog) specified when ordering the drive. You must
adapt the lubricant fill in case of any subsequent changes made to the mounting position
(→ Lubricant fill quantities).
Lubricant table The lubricant table on the following page shows the permitted lubricants for SEW-
EURODRIVE gear units. Please refer to the following legend for the lubricant table.

Anti-friction
bearing greases
The anti-friction bearings in gear units and motors are given a factory-fill with the greas-
es listed below. SEW-EURODRIVE recommends regreasing anti-friction bearings with
a grease fill at the same time as changing the oil or replacing the anti-friction bearings.
CLP = Mineral oil
CLP PG = Polyglycol (W gear units, NSF certified H1)
CLP HC = Synthetic hydrocarbons
E = Ester oil (water hazard class 1 (German regulation))
HCE = Synthetic hydrocarbons + ester oil (NSF certified H1)
HLP = Hydraulic oil
= Synthetic lubricant (= synthetic-based anti-friction bearing grease)
= Mineral lubricant (= mineral-based anti-friction bearing grease)

The following grease quantities are required:
• For high-rpm bearings (gear unit input end): Fill the cavities between the rolling ele-
ments one-third full with grease.
• For low-rpm bearings (in gear units and at gear unit output end): Fill the cavities be-
tween the rolling elements two-thirds full with grease.
