5-3 Lubrication Specifications and Considerations
Lubricating Bearings
All beside-the-press granulators and accessories are supplied with pillow block bearings which
are pre-lubricated at the factory.
The external mounting of bearings on ACS Group beside-the-press granulators result in a
trouble-free, low maintenance, and long-lived bearing design.
The pillow block bearings used require a high quality, lithium-based EP (extreme pressure) type
of grease which conforms to the 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.

Pillow block bearings should be lubricated with care. Too much grease applied to the bearings at
one time can rupture bearing seals. Under normal operating conditions, a moderate amount of
grease applied every 2,000 hours should be adequate to ensure long life.
Severe operating
conditions require more frequent lubrication intervals.
Lubricating Chains
The chain should be lubricated with an oil having a viscosity similar to SAE40 or SAE50. Be
careful not to over-lubricate the chain, as this could result in dripping or oil throw-off during
operation.
