7.4.1 Bearing with grease lubrication
The pumps with bearing brackets 25, 35 and 45
use an antifriction bearing, lubricated for service
life, on the drive side and on the pump side.
The pumps with bearing brackets 55 and 65 must
be greased through grease nipples 63.60.
Grease lubrication:
The bearings receive their first engreasing at the
supplier plant.
Grease amount per ball bearing:
bearing housing 55: (shaft end diameter at the
driving side 50 mm) 30 gramme
bearing housing 65: (shaft end diameter at the
driving side 60 mm) 40 gramme

lubrication every 5000 hours every 2500 hours
at the latest after 12 months
After about 10000 hours of activity or the latest
after two years, the bearings have to be
disassembled, washed and refilled with grease.
Under extremely unfavourable circumstances (wet
or dusty environment or high temperatures of the
environment) the lubrication intervals have to be
chosen considerably shorter.
For renewing or adding lubrication grease, only
lithium soap bearing grease have to be utilised
(e.g. Mobilux 2, Shell Aero Grease 16, Esso
Unirex N3).
