Cylindrical Roller Bearing Sizes

Cylindrical roller bearing sizes are commonly referred to by several abbreviations, including DN, kS, kS2, kS3, kS4, kS5, kS6, kS8, kS9, kS10, and kS12. These acronyms are used to describe the different sizes of cylindrical roller bearings. You can use them to compare the performance of different types of bearings, or to find out which one is right for your needs.

Cylindrical roller bearings are designed to carry a sufficient radial load for continuous operation. The minimum radial load is P=C0r/60, but external forces and the weight of supported parts can cause the radial load to be higher. Hence, the radial load should be checked in advance to ensure that it is appropriate for the application.

Cylindrical roller bearings are available in two basic designs: sealed and split. The sealed design protects the rollers from contaminants, providing lower friction and longer service life. The split design simplifies maintenance.
