otherwise it will penetrate into the interior of the machine. The amount of grease used for
each regreasing operation is shown on the lubricant plate. When changing the bearings
remove the spent grease that has collected in the spent grease chamber and in the outer
bearing cover.
To remove the spent grease, proceed as follows:
1. Remove the transmission element.

Lubrication

Regreasing intervals
The regreasing intervals are specified on the lubricant plate of the motor.
NOTICE
Comply with the lubrication intervals
The bearings can be damaged if the lubricating intervals are not maintained.
Keep to the general lubrication interval, see Maintenance intervals.
The lubrication intervals apply for normal loads, operation at speeds corresponding to those
specified on the rating plate, precision-balanced running, almost neutral ambient air, and the
use of high-quality rolling-contact bearing greases.
Grease types
The following high-quality rolling-contact bearing greases have been tested and are suitable:
Table 9-2
K3N greases
ESSO / Unirex N3
ARAL / Aralub 4340
DEA / Glissando 30
ESSO / Beacon 3
FUCHS / Renolit FWA 220
WINTERSHALL / Wiolub LFK 3
LUBRICANT CONSULT / Sintono GPE 702
These greases have lithium soap as the thickening agent and mineral oil as the base oil.
They exceed the standard requirements of DIN 51825 in several important respects and are,
therefore, compatible with the specified regreasing intervals.
