MSD SABER SERIES SHEARS
TURNTABLE BEARING
LUBRICATION FREQUENCY
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. Converse-
ly, if the old grease is contaminated or deteriorated, the interval should be shortened. Rotating shears in storage
should be lubricated at least every six months.
LUBRICATION PROCEDURES
Bearings are equipped with one to four grease fi ttings, depending upon the model. The grease fi ttings will be
located either on the outside of the bearing (if it is an internal drive rotator) or on the upper head side plate (ex-
ternal drive). To lubricate the bearing, grease a fi tting and then stand clear to rotate the shear. This will uniformly
distribute the grease and effectively fl ush out the old grease and contaminants. Grease the same fi tting again
after rotating before moving on to the next fi tting. Grease each fi tting a total of eight pumps of the grease gun
or until grease escapes through the bearing seals.
Stand clear of the shear while rotating. Grease
a fi tting and then stand clear to rotate the bear-
ing to distribute the grease. DO NOT attempt to
grease the bearing while the shear is rotating or
severe injury could occur.
TURNTABLE BEARING LUBRICANTS
For normal operating conditions, periodic lubrication with lithium Grade 2 extreme pressure grease is recom-
mended. For operation below 32°F (0°C), Grade 0 is recommended. the following table lists typical lubricants
for turntable bearings (comparable lubricants by other manufacturers may also be used):
