7308B 40*90*23mm Single Row Angular Contact Ball Bearing

The 7308B bearing,with a bore diameter of 40 mm, outside diameter 90 mm, and width of 23 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 7308B 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.

What's the Applications of the 7308B Bearing?

The 7308B angular contact ball bearing is ideal for applications needing to handle both radial and axial loads with high precision and speed. Key applications include:

1. Machine Tool Spindles: Offers high rigidity and speed (up to 6300 rpm with grease, 8500 rpm with oil), improving machining accuracy and stability.
2. Automotive Transmission Systems: Handles alternating loads and high axial forces well, suitable for transmissions and differentials.
3. Industrial Power Equipment: Features high load capacity and wear resistance, beneficial for motors, compressors, and pumps.
4. High-Speed Precision Machinery: Designed for low vibration at high speeds, perfect for devices like centrifuges and precision instrument spindles.
