Note: The chart above is based on motors with grease lubricated bearings, running at speeds of
1750 RPM or less, and operating within an ambient temperature range of between 0°F to 120°F (-
18°C to 49°C).
Gear Reducers

Ventilation - During normal operation gear reducers build up heat and pressure and must
be vented to protect the seals and gears.

Cleaning - After approximately two to three weeks of operation, the reducer must be
drained, flushed out, and refilled to the correct level with fresh oil. This is done to remove
any brass particles created during the normal wear-in period of the worm gear. From then
on, the oil should be changed every 2500 hours of operation or every 6 months, whichever
comes first.
Note: Where high temperatures and/or a dirty atmosphere exist, more frequent changes may be
necessary. Periodically check to ensure the correct level of oil is in the reducer. Too little oil will
cause accelerated wear on the gears. Too much oil can cause overheating, seal deterioration, and
leakage.

Lubrication – See Fig. 12 for gear drive lubricant spec. The correct oil to use in your reducer
depends on the worm’s RPM, ambient temperature, and the severity of use. The following
chart can be referred to for reducers with 1750 RPM worm speed, operating under normal
duty, and with ambient temperatures from 18°F to 125°F (-8°C to 52°C).
