Oil compensator
Project Planning for Gear Units
5.2 Oil compensator
The oil compensator allows the lubricant/air space of the gear unit to expand. This
means no lubricant can escape the breather valve at high operating temperatures.
SEW-EURODRIVE recommends to use oil compensators for gear units and gearmotors
in M4 mounting position and for input speeds > 2000 rpm.
The oil compensator is suppled as assembly kit. It is intended for mounting onto the
gearmotor. However, if installation space is limited or if the compensator is intended for
gear units without motor, it can be mounted to nearby machine parts.
