7348 BCBM Bearing Product Overview & Core Advantages
The 7348 BCBM is a single row angular contact ball bearing designed for high-precision applications requiring exceptional rigidity and load capacity. Engineered to accommodate combined loads—simultaneously handling significant radial and unidirectional axial forces—this bearing is ideal for demanding industrial environments. Its P6 (ABEC-3) tolerance class ensures superior running accuracy, while the optimized 40° contact angle provides excellent axial load support. Manufactured from premium chrome steel and featuring a durable brass cage, the 7348 BCBM delivers reliable performance in high-speed applications up to 1,500 rpm.
