Paired Angular Contact Ball Bearing

Paired angular contact ball bearings: customized combinations for efficient load-bearing solutions Paired angular contact ball bearings are bearing assemblies that combine two or more sets of unidirectional angular contact ball bearings in a specific way (back-to-back, face-to-face, series) and pre-adjusted. Its core value lies in the standardized pairing design, which solves the problem of a single bearing being unable to withstand bidirectional loads or requiring enhanced load-carrying capacity, while ensuring the coaxiality and preload consistency of the bearings in the group. It is widely used in machine tool spindles, precision motors, elevator traction machines and other scenarios with complex load directions and high stiffness requirements. From a structural point of view, paired angular contact ball bearings are based on two sets of unidirectional angular contact ball bearings, and form three typical structures according to the difference in combination methods: one is the **ba…
