Manufacturing Process

Our steel bushings are produced using advanced manufacturing and finishing techniques:

1. CNC Turning & CNC Machining
   Produces precise outer and inner diameters, roundness, and surface smoothness.

2. CNC Milling
   For grooves, notches, flats, or any special geometric features.

3. Forging
   For high-strength forged steel bushings requiring maximum durability.

4. Heat Treatment
   Increases hardness, fatigue strength, and resistance to wear.

5. Grinding & Polishing
   Achieves ultra-fine tolerance and extremely smooth surface finish.

6. Surface Conditioning & Coating
   For corrosion resistance and extended service life.

Material Selection

We provide multiple material options to meet your performance requirements:

Carbon Steel Bushings

These treatments improve corrosion resistance, reduce friction, and extend service life.

Precision & Quality Control

All metal bushings undergo strict quality inspection:

• Digital caliper, micrometer, gauge block measurements

• Roundness and concentricity testing

• Hardness testing

• Tensile strength and fatigue resistance checks

• Surface roughness inspection (Ra requirement available upon request)

We provide tolerance options down to ±0.005mm depending on design requirements.

As a precision steel bushing factory in China, we ensure consistent quality for each batch.

Applications

Our steel bushings are widely used in:

• Automotive components (suspension, steering, transmission systems)

• Industrial machinery (motors, pumps, gear systems)

• Construction equipment (excavators, loaders, cranes)

• Agricultural machinery

• Aerospace equipment

• Marine & offshore machinery

• Robotics and automation systems

• Heavy equipment and mining machinery

Whether for OEM production or custom replacement parts, we deliver reliable performance across industries.
