Gearmotor Maintenance
WARNING
Always ensure equipment is secure and air is disconnected before removing or
performing maintenance on the drive assembly.
All gearmotors are supplied with the correct grade and quantity of lubricating oil for the specified mounting position.
The oil level should be checked periodically. Remove the plated (non-painted) oil level plug. The oil level is correct when
the surface of the oil is level with the lowest point of that tapped hole.
Oil levels and oil quality should be checked at frequent intervals, depending on usage and the operating environment. Oil
changes are required at intervals of 10,000 operating hours or every two years, whichever comes first. If a synthetic oil
lubricant is used, then this period can be extended to 20,000 operating hours or every four years, whichever comes first. In
applications where hostile operating conditions exist, such as high humidity, corrosive environment, or large temperature
changes, the lubricant should be changed at more frequent intervals.
Grease packed bearings should be cleaned and regreased every 10,000 hours or 20,000 hours for synthetic grease. Input
(high speed) bearings should not be overgreased. They should be filled with grease not to exceed 1/3 of the bearing’s free
volume. For output bearings and bearings with replaceable grease shields, fill to 2/3 of their free volume.
When the recommended lubricant is not available, it is permissible to use a lubricant having equivalent characteristics but
we do not recommend that lubricants of different brands be mixed. Under no circumstances should synthetic lubricants be
mixed with one another or with one another or with one having a mineral base.
