Cam
followers and yoke rollers are pre-lubricated with an NLGI grade 2,
lithium soap, mineral oil based grease with EP additives. RBC Roller
type cam followers and yoke rollers are normally lubricated for life
and have no provisions for relubrication. Needle roller type cam followers
require relubrication depending on operating speed, duty cycle, operating
environment, desired service life, etc.
For
relubrication in service, mineral oil, or any good roller bearing grease
on mineral oil basis may be used. Inquire about compatibility of greases
with different base oil and thickener.
Except
for the very small sizes (see tables), cam followers with screwdriver
slots can be relubricated from both ends of the stud and through the
housing. Table 2 lists suitable drive fit Alemite fittings. Plugs are
furnished by RBC to close off unused passages.
