7226 BM Bearing Product Overview & Core Advantages
The 7226 BM is a single row angular contact ball bearing engineered for applications requiring high precision and reliable performance under combined loads. Its 40° contact angle enables it to support significant axial loads in one direction while simultaneously handling radial loads, making it ideal for demanding industrial applications. Manufactured to P6 (ABEC-3) tolerance class, this bearing offers exceptional dimensional accuracy and rotational precision. The brass cage ensures stability at high speeds, contributing to its excellent performance in high-speed machinery.
