50mm bore 7310B Single Row Angular Contact Ball Bearings 50*110*27 mm Open Type

7310B 50*110*27mm Single Row Angular Contact Ball Bearing   

 

The 7310B bearing,with a bore diameter of 50 mm, outside diameter 110 mm, and width of 27 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 7310B 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 7310B Bearing?

 

The 7310B 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. Industrial Manufacturing

Machine Tools: High-precision spindles, lathes, and CNC machines needing to handle combined radial and axial loads.

Material Processing: Equipment like concrete mixers and rubber calenders, where it withstands shock loads and vibrations.

2. Transportation and Automotive

Automotive Parts: Steering systems, wheel bearings, and gearboxes; lightweight designs improve efficiency and handling.

Railway Equipment: Transmission systems and brakes, offering fatigue resistance for extended maintenance intervals.

3. Energy and Heavy Industry

Mining and Metallurgy: Crushers, mills, and rolling equipment that endure high dust, heat, and heavy loads.

Power and Fluid Machinery: Fans, pumps, and hydroelectric generators, designed to work in humid or poorly lubricated environments.

4. Special Environments

High Temperature/Corrosion: Stainless steel versions (e.g., SIAIF brand) resist corrosion in food processing and chemical industries.

Robotics: Used in robotic joints and precision motion components.
