Steel Hardened Bushings

Premium Case Hardened Steel Bearings: Engineered for Maximum Durability

Maximize the lifespan and performance of your heavy-duty equipment with our precision-engineered Case Hardened Steel Bearings. In extreme environments characterized by high impact and abrasive grit, standard soft-steel bushings often fail due to surface deformation or rapid wear. Our case-hardening process solves this by creating an ultra-hard outer shell while maintaining a tough, resilient core, ensuring your machinery stays operational longer.

Why Choose Case Hardened Bearings?

The primary purpose of case hardening (also known as surface hardening) is Wear Resistance and Structural Integrity. By chemically and thermally transforming the steel's surface, our bearings:

Resist Surface Wear: The high-carbon exterior (typically HRC 58-62) stands up to constant friction and abrasion.

Absorb Impact: The ductile inner core prevents the bearing from shattering or cracking under heavy shock loads.

Optimize Tolerance: Precision grinding after heat treatment ensures a perfect fit, reducing vibration and noise.

Strategic Hardening Processes & Their Applications

We offer a comprehensive range of industry-standard materials and heat-treatment depths to suit your specific operational dynamics:

Typical Applications

Our case hardened steel bearings are the backbone of heavy-duty industrial equipment, including:

Construction & Earthmoving: Bucket pins, links, and boom pivots for excavators and loaders.

Mining & Quarrying: Crusher components and conveyor system rollers

Forestry & Agriculture: Heavy-duty grapples, harvesters, and tilling equipment.

Material Handling: Forklift mast rollers and heavy-load palletizing systems.

Hardening Type	Best For	Functional Benefit
Carburizing	Deep wear protection	Creates a thick, hard layer for the most abrasive environments.
Nitriding	Corrosion resistance	Enhances surface hardness while adding a layer of chemical protection.
Induction Hardening	Large diameter parts	Targeted hardening of specific wear areas for heavy-duty pins.
Carbonitriding	Precision small parts	Improves wear resistance for smaller, complex-shaped bushings.
Through Hardened	Uniform high-strength	Consistent hardness throughout the part for specialized high-stress parts.
