Rotator Maintenance
TURNTABLE BEARING LUBRICATION
LUBRICATION FREQUENCY
Rotating shears in storage should be lubricated at least every six months. Equipment operating frequently in
extreme environments should be lubricated at least every eight hours. If the old grease is noted to be in good
condition and free of contamination, the interval may be extended. Conversely, if the old grease is contami-
nated or deteriorated, the interval should be shortened.
LUBRICATION PROCEDURES
Bearings are equipped with one grease fi tting located on the upper head for the turntable bearing and one fi t-
ting for the pinion gear. Look for the yellow grease stickers to locate the fi ttings. It is recommended to rotate
bearing while greasing in order to uniformly distribute the grease and to most effectively fl ush out the old
grease and contaminants. The bearing should be turned through two full revolutions while greasing through
any one fi tting. Apply 12 to 15 shots of grease.
TURNTABLE BEARING LUBRICANTS
For normal operating conditions, periodic lubrication with lithium Grade 2 extreme pressure grease is recom-
mended. For operation below 32ºF, Grade 0 is recommended. The following table lists typical lubricants for
turntable bearings.
