PX 4 Point Contact Ball Bearing Series Thin WallBearing Introduction

The PX series refers to a type of thin-wall bearing with four-point contact ball design. These bearings are engineered for applications where radial, axial, and moment loads need to be accommodated simultaneously. The four-point contact design allows for greater load-carrying capacity and increased flexibility in mounting arrangements.
