AI Overview
The 7310B is a high-capacity single-row angular contact ball bearing with a 40° contact angle, designed for high axial rigidity and high-speed operation. With dimensions of 50mm bore, 110mm outer diameter, and 27mm width, it commonly features brass or pressed steel cages to manage, in addition to radial forces, heavy axial loads in one direction.
Key Characteristics and Applications
- High Axial Load Capacity: The 40° contact angle (denoted by 'B') provides superior axial load capacity compared to smaller angles.
- High Rigidity: Excellent for precision applications, often used in machine tool spindles, gearboxes, pumps, and automotive machinery.
- Matched Pairs: Frequently paired (X, O, or Tandem) to handle axial loads in both directions and increase rigidity.
- Component Structure: Features one high and one low shoulder, enabling the use of a larger number of balls.
- Variants: X-life (XL) variants exist for improved performance, higher load ratings, and longer life.
Common Designators
- 7310B: Standard 40-degree bearing.
- 7310B-XL/7310B-XL-JP: FAG/Schaeffler premium, often with brass or steel cage (JP).
- 7310BG/7310BG-SKF: SKF variant with a large number of balls, suited for universal matching.
