Regreasing intervals and grease types
Regreasing intervals
On machines with a regreasing device, the regreasing intervals are stated on the lubricant
plate attached to the machine. Regrease the machine at the prescribed intervals.
Grease types
A grease rated for temperatures ranging down to -20 °C is normally used to initially lubricate
rolling-contact bearings. The following high-quality greases for rolling-contact bearings are
suitable and tested for temperatures down to -20 °C.
Table 9-2
K3N greases
ARAL / Aralub 4340
DEA / Glissando 30
ESSO / Beacon 3
ESSO / Unirex N3
FUCHS / Renolit FWA 220
SHELL / Gadus S2 V100 3
SHELL / Alvania R 3
WINTERSHALL / Wiolub LFK 3
These greases have lithium soap as the thickening agent and mineral oil as the base oil. They
exceed the normal requirements of DIN 51825.
If you use other K3K or K3N greases, some of which only meet the minimum requirements per
DIN 51825, halve the regreasing intervals. K3N greases have higher temperature reserves
than K3K greases.
NOTICE
Damage from mixing lubrication types
If greases and oils with different soap or oil bases are mixed, their lubricating properties may
no longer be assured.
Mixing low-temperature grease with normal temperature grease can cause lumps to form in
the lubricant. and risk thermal damage to the rolling-contact bearing.
Never mix greases that have different thickening agents and different base oils.
Special types of grease are used on machines that are designed for use at temperatures below
-20 °C. These grease types are specified on the lubricant plate. Other types of grease are not
permitted.
