7313 ACCBM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The single row design with a 25° contact angle provides excellent resistance to deformation under load, ensuring precise shaft positioning. It offers a dynamic load rating of 29,700 lbf and a static load rating of 21,712 lbf, making it suitable for demanding applications with significant combined radial and axial loads.
- High-Speed Performance: The robust brass cage (CC) maintains ball alignment and stability, contributing to a high limiting speed of 9,500 rpm. The optimized internal geometry minimizes friction and heat generation.
- Precision Engineering: Manufactured to P6 tolerance class (ABEC-3), this bearing guarantees minimal runout and vibration, which is critical for high-precision machinery.
- Material & Durability: Constructed from chrome steel for both rings and balls, the bearing provides high hardness, wear resistance, and a long operational life under standard temperature conditions (-30°C to 110°C).
