Lubrication Requirements
This section describes the parts of the machine that require periodic lubrication, and specifies the
lubricants. In addition, it explains how to maintain the lubrication systems on the machine.
If the bearing is equipped with a grease fitting (Zerk Fitting).
The Zerk fitting is basically a valve that opens under pressure to allow
lubricant to pass through a channel and be forced into the voids of the
bearing. When the pressure stops, the ball returns to its closed position.
The ball excludes dirt and functions as a check valve to prevent grease
escaping back out of the fitting.
The ball is almost flush with the surface of the fitting so that it can be
wiped clean to reduce the amount of debris carried with the grease into
the bearing.
Note: Bearings without grease fittings have been pre-lubri-
cated at the factory and do not require further lubrica-
tion.
Note: Make sure to clean excess grease to avoid contact
with feed belts, clamping areas, or the door.

Pillow Block Bearing Housings
A pillow block is any mounted bearing where the mounted shaft is in a parallel plane to the
mounting surface, and perpendicular to the center line of the mounting holes, as compared to dif-
ferent types of flange blocks or flange units. The type of rolling element defines the type of pillow
block.
