Purpose of Bearing Lubrication || Dynaroll

TECHNICAL INFORMATION

Lubrication increases bearing life in most operating environments. The positive effects of lubrication may be summarized as follows:

A lubricant film reduces friction and wear between the balls and raceways of the bearing, extending fatigue life.
Dissipates frictional heat and can provide additional cooling if lubricant is circulated.
Guards against corrosion and may help prevent foreign material from entering the bearing.

In addition to these general benefits, a good lubricant should have the following intrinsic properties:

Resists change in structure or consistency during prolonged service.
Resists excessive viscosity changes at temperature extremes.
Resists leakage, dripping or throw-off from rotating surfaces.
Compatibility with materials used in bearings, particularly seals and retainers.
Tolerate some contamination, including moisture, without loss of characteristics.

Other factors that are affected by lubricant choice include:
