Regreasing intervals for rolling-contact bearings, grease type
Grease types
The regreasing intervals, the amount of grease and the type of grease used for the initial
lubrication are specified on the motor's lubrication instruction plate. If the specified number of
operating hours is not reached within three years, the bearings must be regreased ahead of
schedule during the main inspection. For the standard range of applications, a grease for
temperatures down to -20°C is normally used for the initial greasing of the bearings. The
amount of grease for the initial lubrication is 25% to 35% of the free bearing volume.
You must not run the motor for a long period of time at speeds less than 10 rpm, because no
lubricating film will form.
The following high-quality greases for rolling-contact bearings are suitable and tested for
temperatures down to -20°C.
