How to properly mount thin section bearings: a new Kaydon Bearings …

For torque-sensitive and high-speed appliions, duplex pairs of angular contact bearings are generally used in place of a single four-point contact bearing. Angular contact (Type A) bearings Angular contact ball bearings can take an axial (thrust) load in only one direction, and therefore are almost always used in pairs.
