Lubrication Requirements
This section describes the parts of the machine that require periodic lubrication, and specifies the lubri-
cants. In addition, it explains how to maintain the lubrication systems on the machine.
Linear Bearings
If the bearing is equipped with a grease fitting, it
should receive 1 Gram (one pump from grease gun)
of Dura-Lith Grease (KVAL P/N Lube EP-2) every
30 days. Bearings without grease fittings have been
pre-lubricated at the factory and do not require fur-
ther lubrication.
Flange Bearing and Pillow Blocks
Use Dura-Lith grease: 1 gram every 60 days.
