7038 BGM Bearing Product Overview & Core Advantages
The 7038 is a single row angular contact ball bearing designed for high-precision applications requiring exceptional performance under combined loads. Engineered with a 40° contact angle, this bearing excels at handling significant axial loads in one direction while simultaneously supporting radial loads. Manufactured to P6 (ABEC-3) tolerance class, it delivers the dimensional accuracy and running precision essential for high-speed operation up to 2,400 rpm. Its robust construction from chrome steel ensures high rigidity and long service life in demanding industrial environments.
