Professional Manufacturer Hardened Steel Bushings 30X40X40mm

Description

Our Professional Manufacturer Hardened Steel Bushings are engineered to deliver unmatched strength and wear resistance in heavy-duty industrial, automotive, and construction applications. Crafted from through-hardened steel alloys (SAE 4140/4340), these bushings undergo precision heat treatment to achieve a Rockwell C hardness of 50-55 HRC. As a factory-direct supplier, we offer customizable dimensions, rapid prototyping, and competitive pricing without compromising quality.

Key Features & Benefits

1.Through-Hardened Steel Construction

• Heat-treated to 50-55 HRC for superior surface hardness and core toughness.
• Resists deformation under shock loads and vibrations.

2.High Load & Wear Resistance

• Withstands radial loads up to 70 MPa and axial loads in compact designs.
• Ideal for heavy machinery, gearboxes, and construction equipment.

3.Precision Customization

• Machined to your exact specifications (ID, OD, length, flange details).
• Supports complex geometries, including stepped sleeves and dual-radius profiles.

4.Corrosion & Temperature Resistance

• Black oxide or zinc-plated finishes for enhanced durability.
• Operates in temperatures from -30°C to 300°C (-22°F to 572°F).

5.Factory-Direct Advantages

• Cost Efficiency: 25–35% lower pricing vs. distributors.
• Quality Control: ISO 9001-certified production with material traceability.
• Rapid Delivery: Lead times as short as 7 days for prototypes.

Applications

• Heavy Machinery: Excavator pins, crane mechanisms, loader arms.
• Automotive: Transmission gears, differential assemblies, suspension systems.
• Industrial: Gearboxes, hydraulic presses, mining equipment.
• Construction: Concrete pump trucks, piling rigs, material handlers.
• Agricultural: Tractor steering mechanisms, harvester components.
