Bearing Lubrication
Many conveyors come equipped with permanently lubricated bearings, which have no
grease zerks. These include 2 and 3-Bolt Flange Bearings with shaft sizes through 7-
7/16". This prevents injecting improper or contaminated grease, and leaves the seals
tighter due to elimination of grease purging. Lubricate other bearings regularly with
approved lubricants from the list below.
Avoid over lubrication, especially when shafts are not turning, as this can blow out the
seals and lead to contamination and failure of the bearing. Exercise extreme caution
around all moving equipment when working close to them, for lubrication. Proper intervals
of bearing lubrication depend on the speed, temperature and working conditions. In
normal applications of 16 hours a day or less, a three month interval is adequate (in clean
conditions). Lock off equipment before attempting to wipe or touch movable equipment of
any kind. Clean off grease zerk fittings before lubrication and wipe excess lube from the
shaft seals so you can observe the amount of newly expelled grease. Remember to
tighten the bearing set screws BI-annually while doing the greasing.

Motor Maintenance
At regular intervals, check that the motor electrical connections are tight and not corroded.
Blow clean any open frame motors, and clean off any dust or debris so proper amounts of
heat may be radiated. If motors consistently become covered with debris, construct a
guard above the, which does not hinder heat radiation.
Lubricate any motors with grease fittings every two years unless conditions are extremely
dirty or damp. Lubricate any motors with sleeve bearings with 10- 15drops of SAE # 20
non-detergent or motor oil every year (more often if dirty or damp).
New motors are more efficient, but run at higher temperatures that you may be used to.
Do not become alarmed unless the ambient temperatures at your drive section are >104
F. At these high temperatures, normal motors may overheat at full loads, and special
o
high-temperature motors may be required.
