Lubrication Information Of Radial Bearings

Lubricant selection is of critical importance for the performance of a ball bearing. It affects Life, Torque, Speed, Noise, Grease migration, Outgassing, Temperature effects and rust prevention.

The two basic types of lubricants available are oil and grease.

Oil Lubricants

Applications that require extremely low torque or narrow range of torque variation, are suited to use oil as a lubricant.

Grease Lubricants

Greases are comprised of a base oil and a thickener. The life obtained from greases is considerably greater than that of just oil. This is because of a continuous mechanism of lubrication by base oil separation coming from the construction of the thickener.
Calculating grease life and performance in sealed-for-life ball bearings includes many complicated factors, such that grease life calculation formulas in the industry at this time will likely show different results than actual life.
In recent years, using plastic material around the bearing has become more common, so the proper selection of lubricant is even more critical to prevent compatibility issues.
Miniature and instrument ball bearings are typically filled with a 30% (±5%) by volume fill quantity.
