7305 ACCBM Bearing Product Overview & Core Advantages
The 7305 ACCBM is a single row angular contact ball bearing designed for high-precision applications requiring exceptional rigidity and speed capabilities. Engineered to accommodate combined loads (simultaneous radial and axial loads), this bearing features a 25° contact angle for optimal axial load capacity. Manufactured to P6 (ABEC-3) tolerance class, it delivers superior running accuracy and reliability in demanding industrial environments. The brass cage construction ensures stable operation at high rotational speeds up to 22,000 rpm.
