Note
Operating conditions and characteristics can vary widely. For this reason, only general
maintenance intervals can be specified here.
9.1.2 Regreasing intervals and types of grease for operating rolling-contact bearings
Regreasing intervals
The regreasing intervals in operating hours and the grease type are stated on the machine's
lubricant plate. Regardless of the actual number of operating hours reached, the machine
must be regreased at least once a year. The lubrication information can be found on the
lubricant plate.
Grease types
For the standard range of applications, a grease for temperatures down to -20 °C is normally
used for the initial greasing of the bearings. If the motors were ordered for use in the
extended temperature range of below -20 °C, the permissible type of grease is indicated on
the lubrication instruction plate. The following high-quality greases for rolling-contact
bearings are suitable and tested for temperatures down to -20 °C.
Table 9-1 Suitable greases for rolling-contact bearings down to -20°C
K3N greases
ARAL / Aralub 4340
DEA / Glissando 30
ESSO / Beacon 3
ESSO / Unirex N3
FUCHS / Renolit FWA 220
SHELL / Alvania RL3
WINTERSHALL / Wiolub LFK 3
MOBIL / Mobilith SHC 100
CP Nr. 337-161-916 NLGI Nr. 2
SHELL / Cyprina - NLGI Nr. 3
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.
The regreasing intervals should be halved if other K3N greases that possibly only fulfill the
minimum requirements laid down in DIN 51825 are used.
