Grease lubricated bearing arrangements are suitable for a wide range of speeds. Lubricating super-precision bearings with suitable quantities of good quality grease permits relatively high speed operation without an excessive rise in temperature.

The use of grease also means that the design of a bearing arrangement can be relatively simple because grease is more easily retained in a bearing arrangement than oil, particularly where shafts are inclined or vertical. Grease can also contribute to sealing the arrangement against solid and liquid contaminants as well as moisture.
