9 Routine Maintenance
9-1 Lubrication Specifications
9-1-1 Description
All Sterling BP1600 Series machines are equipped with
rotor bearings that are pre-lubricated & sealed from the
factory.
Mounting of the bearings on the Sterling BP1600 Series
machines results in trouble free, low maintenance, and long
lived bearing design.
If seals are damaged and the rotor bearings required
lubrication, use a high quality, lithium based, extreme
pressure (or EP) type of grease, which conforms to NGLI
Grade 2 consistency. This grease has been chosen due to
its suitability for use in heavy-duty applications under
heavy shock loads. It also contains rust inhibitors, has high
temperature stability, and exhibits good water resistance.

NOTE: The bearings should be lubricated with care. Too much
grease applied to the bearings at one time can rupture the
bearing seals. Under normal operating conditions, a
moderate amount of grease applied every 2000 hours
should be adequate to ensure long life. Severe-operating
conditions will require more frequent lubrication intervals.
