Precision Forged Bronze Bushing

Precision forged bronze bushing is a high-density, high-strength and highly wear-resistant bronze sleeve manufactured by precision forging followed by precision machining. It is mainly used in heavy-duty, wear-resistant and high-precision mechanical parts.

Production Process of Precision Forged Bronze Bushing
1. Select suitable materials and heat them.
2. Form under high pressure in a die using precision forging equipment.
3. Conduct precision machining to ensure product dimensions.
4. Carry out surface treatment for better corrosion resistance and appearance.
Perform quality inspection.

First of all, bronze is not a cheap material. It is more expensive than iron, aluminum and brass. Alloys containing precious metals like tin will further increase the cost. In addition, bronze is quite wear-resistant, which also leads to higher processing costs.
However, some of its advantages are irreplaceable. In applications that require high strength, wear resistance, seawater corrosion resistance and long service life, bronze can provide greater value and offer a better overall cost-performance ratio.

1. Engineering Machinery: Excavator bushings, bucket shaft sleeves, pin shaft sleeves
2. Hydraulic Equipment: Hydraulic motor bushings, hydraulic pump bushings
3. Ship/Marine: Stern shaft sleeves, steering gear bushings, seawater pump sleeves
4. Valves & Molds: Guide sleeves, support sleeves
5. Automotive & Reducers: Worm wheel supporting bushings, low-speed heavy-duty shaft sleeves

1． Heat Treatment: Annealing is a mandatory process to relieve forging stress and avoid deformation and cracking. Solution and aging treatment is often applied to aluminum bronze to further enhance hardness, strength and wear resistance.
2． Fine Machining: An essential process for high-end and high-precision products.
3． Surface Treatment: Common treatments include phosphating, oxidation and anti-rust treatment, selected according to product requirements and application environment.
4． Oil Groove & Oil Hole Machining: Standard configuration for wear-resistant components.
5． Strengthening Treatment: Processes such as rolling and shot peening are adopted for high-end heavy-duty products to improve performance.
