Applications of Bearing Steel

Bearing steel is a specialized steel grade specifically designed for manufacturing inner and outer rings, as well as rolling elements, of rolling bearings. It features high hardness, superior wear resistance, high compressive strength, exceptional fatigue life, and excellent dimensional stability. Its core applications span the following fields:
Rolling Bearing Manufacturing
Core Function: Rolling bearings are critical components in mechanical equipment, reducing friction and supporting rotating parts.
Specific Components:
Inner and Outer Rings: Support rolling elements and withstand radial and axial loads.
Rolling Elements (Balls/Rollers): Directly bear loads and enable rolling friction.
Applications: Automotive engines, machine tool spindles, wind turbines, aerospace equipment, etc.
High-Precision Mechanical Parts
Precision Instruments: Components requiring extreme dimensional stability, such as watches and gyroscopes.
Measuring Tools: Key parts of precision instruments like micrometers and vernier calipers.
Case Example: Bearing steel components in Swiss watches ensure long-term accuracy.
High-Load, High-Speed Equipment
Automotive Industry: Crankshaft bearings, transmission bearings.
Aerospace: Main spindle bearings for aircraft engines, helicopter rotor bearings.
Energy Sector: Main spindle bearings for wind turbines, bearings for nuclear power plant equipment.
Special Environment Applications
High-Temperature Environments: Bearings for industrial furnaces and high-temperature rolling mills.
Vacuum Environments: Bearings for spacecraft attitude control systems.
Corrosive Environments: Bearings for chemical equipment (requires surface treatment).
