7212 BEGAM Bearing Product Overview & Core Advantages
The 7212 BEGAM is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing features a 40° contact angle and P6 (ABEC-3) precision class, delivering exceptional running accuracy and rotational stability. Its optimized design enables it to accommodate significant axial loads in one direction while simultaneously handling radial loads, making it ideal for applications demanding high rigidity and precise shaft positioning. The brass cage ensures reliable operation at high rotational speeds up to 9,500 rpm.
