The 7307 B RICH is a heavy-duty single row angular-contact ball bearing engineered for applications requiring high rigidity and superior axial load support. The designation B indicates an increased 40° contact angle, which is specifically optimized for managing substantial unidirectional axial forces alongside combined radial loading. With dimensions of 35 mm bore, 80 mm outer diameter, and a 21 mm width, this bearing is built for demanding environments in industrial gearboxes, pumps, and machine tools. It utilizes a robust steel cage, which is guided by the rolling elements, offering high strength and reliable performance, particularly under rigorous operating conditions and high speeds. Due to its separable design, this bearing can accommodate precision adjustments and flexible mounting arrangements.
Key Performance Advantages:
- High Axial Load Capacity: The 40° contact angle (B) ensures excellent support for substantial unidirectional axial forces.
- Rigid Construction: Single row design provides excellent radial and axial rigidity for accurate guidance.
- Durable Steel Cage: Offers high resistance and reliable operation, suitable for high-stress applications.
- RICH Quality: A high-precision component built for stability and long-term industrial service.
