5.4 Bearing Lubrication
Grease fittings are accessible when hopper and cutting chamber are pushed back. Grease twice yearly with
Gulflex “A” multi-purpose or equivalent. Grease fittings are located on rotor bearings. Lubricate the chain every
six months.
All SEM security disintegrators and accessories are supplied with pillow block bearings which are pre-
lubricated from the factory. The external mounting of bearings on SEM Security Disintegrators results in a
trouble free, low maintenance, and long life 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.

The pillow block 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
