PA Angular Contact Ball Series Thin Wall Bearings


PAAngular Contact Ball Series

Introduction to PA angular contact ball series thin wall bearings

Angular contact ball bearings are a type of rolling-element bearing designed to support both radial and axial loads by allowing the balls to make contact at an angle with the inner and outer raceways. The PA angular contact ball series refers to a specific type of angular contact ball bearings that are characterized by their thin wall construction. These bearings are designed with a reduced cross-sectional thickness, making them suitable for applications where space is limited and weight is a critical factor.
