7306 ACCBM Bearing Product Overview & Core Advantages
The 7306 ACCBM is a single row angular contact ball bearing designed for high-precision applications requiring superior performance under combined loads. Engineered with a 25° contact angle, it efficiently handles significant axial loads in one direction alongside radial loads. Manufactured to P6 (ABEC-3) tolerance, this bearing ensures high running accuracy and rotational stability. Its brass cage and optimized internal geometry contribute to reliable operation at high speeds, making it an ideal choice for demanding industrial environments where high rigidity and precision are paramount.

| A | 25° contact angle, optimized for high axial load capacity |
| C | Internal design with optimized internal clearance |
| BM | Brass cage (machined), providing excellent high-speed stability and strength |
7306 ACCBM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 25° contact angle provides excellent resistance to axial loads while maintaining robust radial load capacity. The optimized raceway geometry and chrome steel construction ensure dimensional stability under heavy combined loads.
- High-Speed Performance: The precision-machined brass cage (BM) ensures smooth operation and guidance of the balls at high rotational speeds, contributing to the bearing's limiting speed of 19,000 rpm.
- Precision & Accuracy: Manufactured to P6 tolerance class (ABEC-3), this bearing guarantees minimal runout and high rotational accuracy, which is critical for precision machinery.
- Durability & Reliability: The use of high-grade chrome steel for both rings and balls, combined with the robust brass cage, ensures long service life and reliable performance in a wide temperature range (-30°C to 110°C).
7306 ACCBM Bearing Typical Application Areas
