- High hardness and toughness: Bearing steel is prized for its high hardness and outstanding toughness. Its hardness ensures shape stability under heavy loads and high-speed rotations, resisting surface wear effectively. Its superior toughness allows it to flex without fracturing under extreme conditions, crucial for prolonged use and varying temperatures. These properties make it ideal for precision mechanical parts and reliable engineering components.
- Low friction: Bearing steel is highly regarded for its exceptional low-friction properties. Achieved through meticulous surface treatments and specialized lubrication techniques, it effectively minimizes friction and wear between metal surfaces. This not only ensures stable and efficient performance during high-speed operations and extended usage but also reduces energy consumption and extends the lifespan of components, making it an invaluable choice for demanding engineering applications.
- High precision： Bearing steel is renowned for its precision manufacturing processes. Through stringent controls and meticulous procedures, it ensures that products adhere to exacting engineering standards in terms of dimensions and shapes. This precision guarantees precise bearing clearances and smooth operational performance after installation, making it indispensable for high-precision applications in automotive, aerospace, and industrial machinery sectors.
- Wide Range of Application： Bearing steel is valued for its high hardness, toughness, and low friction, making it essential in manufacturing bearings and rolling components. It ensures reliable operation in automotive engines, transmissions, and wheel bearings, and plays a crucial role in aerospace for aircraft engines, landing gear, and flight controls. It also meets complex engineering demands in industrial machinery, power equipment, and precision instruments.
