High Light Open angular bearing ，55mm Bore Angular Contact Ball Bearings
55mm Bore 7311B Single Row Angular Contact Ball Bearings 55×120×29 mm Open Type
7311B 55×120×29mm Single Row Angular Contact Ball Bearing
The 7311B bearing features a bore diameter of 55 mm, outside diameter of 120 mm, and width of 29 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.

7311B Angular Contact Ball Bearing technical diagram 7311B Angular Contact Ball Bearing application example
Performance Features
  • 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.
Applications
The 7311B bearing, as an angular contact ball bearing, is widely used in the following fields due to its high speed, high load capacity, and ability to carry bidirectional axial loads:
Industrial Machinery and Equipment
  • Metalworking: Used in coil plate machines, nail heel machines, and other equipment requiring high-precision rotary support.
  • Chemical and Mixing: Suitable for dry powder mixers, chemical equipment, and vibrating dryers, withstanding medium loads in corrosive environments.
Engineering and Construction Machinery
  • Lifting and Transport: Applied in tower cranes, conveyors, and similar equipment, adapting to heavy and shock loads.
  • Machinery Components: Provides stable support for drill bushings, hydraulic systems, and other components.
Special Equipment and Precision Instruments
  • Electronics Manufacturing: Ensures low-vibration operation in terminal machines, pick-and-place machines, and semiconductor packaging equipment.
  • Laboratory and Testing: Supports high-precision measurements in hardness testers, vibration platforms, and similar devices.
Automotive and Transportation
  • Automotive Components: Optimizes transmission efficiency in steering systems, gearboxes, and hub bearings.
  • Emerging Applications: Some companies are exploring its use in flying car hub bearings.
Other Applications
  • Agricultural Machinery: Used in transmission components of harvesters and irrigation equipment.
  • Home Appliances: Suitable for high-speed applications like shielded pumps and air conditioning compressors.
