7307B 35*80*21mm Single Row Angular Contact Ball Bearing

The 7307B bearing,with a bore diameter of 35 mm, outside diameter 80 mm, and width of 21 mm.This single row angular contact ball bearing can support both radial and axial loads simultaneously, with the axial load being accommodated in one direction only. Depending on the specific model, this bearing is capable of operating at high speeds or even extremely high speeds. Compared to deep groove ball bearings, it can withstand significantly greater unidirectional axial forces.It is particularly well-suited for situations needing robust handling of both radial and significant unidirectional axial loads at high speeds.

What's the Performance Features of 7307B Bearing?

• High-Speed Operation: With minimal friction, this bearing is designed for stable performance at high speeds.
• Precision and Durability: It offers high precision and strength, making it suitable for applications requiring accurate shaft rotation.
• Angular Contact Design: This design efficiently handles both axial and radial loads, enhancing load capacity and extending the bearing's life.
• Single Direction Load Support: Capable of managing axial loads in one direction along with radial loads, ideal for applications where forces act mainly in one direction.
