Bronze Bushing for Mining & Heavy Equipment

Bronze bushings are among the most heavily loaded wear parts in crushers, conveyors, pumps and construction machinery. When a bushing wears out or seizes, the whole machine stops. Xinxiang Haishan Machinery casts and machines custom bronze bushings to your drawing or worn sample, matching the original alloy grade so the replacement fits and performs as intended.

Design & materials

We cast bushings in a range of standard copper alloys, and can also pour to a specified grade. Typical choices include C93200 (SAE 660) tin bronze for medium-load bearings, C93700 for dusty or dirty service, C95400 and C95800 aluminum bronze for high impact and abrasion, and C86300 manganese bronze where high strength is needed. Graphite-plugged self-lubricating bushings are available for locations where grease access is difficult. Wall thickness, oil grooves, flange profiles and tolerances are produced to your drawing.

Typical applications

• Crusher eccentric and frame bushings, plus socket liners
• Conveyor and bulk material handling bearing positions
• Pump, valve and hydraulic wear rings and sleeves
• Construction machinery pivot and boom bushings
• General replacement bushings for mining and quarrying equipment

Manufacturing & inspection

We combine casting and machining in one workshop. Centrifugal casting is used where a denser structure is preferred, while sand casting and metal mold casting suit larger or more complex shapes. Each batch is checked with spectrometer composition analysis and hardness testing before CNC machining to drawing. If you only have a worn part, our team can reverse-engineer it and match the original material.
