7304 BEP Bearing Product Overview & Core Advantages
The 7304 B is a single row angular contact ball bearing designed for precision applications requiring high rotational accuracy and reliable performance. Engineered to accommodate combined loads (simultaneous radial and axial forces), this bearing features a 40° contact angle that provides excellent axial load capacity in one direction. Manufactured to P6 (ABEC-3) tolerance class, it delivers superior running accuracy and is ideal for applications demanding high-speed operation with precise positioning capabilities.
