Although there are many types and varieties of rolling bearings with their own inherent characteristics, rolling bearings have the following characteristics compared to sliding bearings:

(1) The starting friction coefficient is small, and the difference between it and the dynamic friction coefficient is also small.

(2) Standardization and normalization have been promoted internationally, so they can be used interchangeably.

(3) Simplified the structure around the bearing for easy maintenance, modification, and inspection.

(4) Easy lubrication and low lubricant consumption.

(5) Generally, it can withstand both radial and axial loads simultaneously.

(6) It is relatively easy to use under high and low temperature conditions.

(7) The bearing rigidity can be improved by applying a preload.
