7064 BGM Bearing Product Overview & Core Advantages
The 7064 is a single row angular contact ball bearing engineered for applications demanding high precision and robust performance under combined loads. Its defining characteristic is the 40° contact angle, which provides exceptional capacity to handle significant axial loads in one direction while simultaneously supporting radial loads. Manufactured to P6 (ABEC-3) tolerance class, this bearing ensures superior running accuracy, making it ideal for high-speed operations with a limiting speed of 1,400 rpm. The combination of chrome steel rings, chrome steel balls, and a brass cage results in a high-rigidity and durable component suitable for demanding industrial environments.
