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.

Recommended Grease Product Names

Amoco	Amolith EP2
Castrol	EP2
Exxon	Ronex MP
Gulf	Crown #2
Mobil	Mobilith AW2
Shell	Alvania EP LF #2
Sunoco	Sunaplex #2
Texaco	Multifack EP2

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.
