Description

7312B 60*130*31mm Single Row Angular Contact Ball Bearing

The 7312B bearing,with a bore diameter of 60 mm, outside diameter 130 mm, and width of 31 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 7312B 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 7312B Bearing?

The 7312B is an angular contact ball bearing widely used in various industries due to its high precision, high speed, and load-bearing capabilities. Below are its primary application areas:

1. Machine Tools & General Machinery

  • Used in milling machines, broaching machines, and machine guards.
  • Enhances efficiency and stability with high precision and speed.
  • Also used in pressing machines, casting equipment, and heat exchangers for high-load applications [123].

2. Industrial Automation & Special Equipment

  • Common in automation devices like inserter machines, vibratory feeders, and soldering irons.
  • Good sealing and wear resistance make it suitable for dusty or moist environments.
  • Supports high-speed and precise control in magnetizers, reactors, and annealing furnaces [2716].

3. Chemical & Food Processing

  • Found in chemical reactors, pumps, and nonwoven machinery due to its corrosion-resistant materials.
  • Used in food processing equipment like grain processing and washing machines, meeting hygiene standards [12].

4. Printing, Packaging & Textile Machinery

  • Provides high-precision support in printing (e.g., offset printers) and textile machines (e.g., nonwoven machinery).
  • Low friction and compact design reduce energy use and extend life in high-speed operations [1216].

5. Other Special Applications

  • Applied in medical devices, environmental equipment, and livestock machinery.
  • Proven reliable in niche areas like electrostatic generators and shoe-making machines.
