hardened bush is a precision-machined, wear-resistant cylindrical component used to reduce friction and wear between moving parts in mechanical systems. Typically made from hardened steel or alloy materials, these bushings are heat-treated to achieve superior hardness and durability, making them ideal for high-load and high-wear applications.
Key Features:
Manufactured from hardened and ground alloy or carbon steel
High wear resistance and long service life
Suitable for rotating, sliding, or oscillating motion
Available in flanged, straight, or custom forms
Can include inner/outer grinding for precision fits
Applications:
Automotive suspension and steering systems
Construction machinery and excavators
Press tools and dies
Agricultural equipment
Industrial machinery and jigs
Benefits:
Reduces metal-on-metal contact and extends component life
Maintains tight clearances in harsh operating conditions
Supports heavy radial loads
Easy to replace and maintain
Improves reliability and efficiency of mechanical systems

Additional Information
hardened bush (or hardened steel bushing) is a high-strength, cylindrical component used in mechanical assemblies to absorb wear, reduce friction, and guide or locate moving parts. It is commonly used in die sets, automotive linkages, heavy-duty machinery, and pivot points where frequent motion or heavy loads are present.
These bushings are heat-treated to achieve high surface hardness while maintaining a tough, ductile core, ensuring excellent resistance to wear, impact, and fatigue.
⚙️ Material & Hardening Process
Base Materials:
High-carbon steel (e.g., 20MnCr5, 52100, or equivalent)
Alloy steels or tool steels (for heavy-duty industrial applications)
Optional: Stainless steel for corrosion resistance
Heat Treatment:
Induction or through-hardening for uniform hardness
Typical surface hardness: HRC 58–64
Case depth: Customizable based on application (typically 0.8–2.5 mm)
Surface Finish:
Ground and polished inner diameter for tight tolerances
Outer diameter may be ground or precision turned
Coatings (optional): Black oxide, phosphate, or anti-rust oil
