Flanged Bronze Bushings for Mining & Heavy Equipment

A flanged bronze bushing combines a plain bearing sleeve with an integral flange, so the part carries radial load while the flange locates the assembly axially and resists end-float. In mining and heavy equipment this is often the difference between a joint that stays put under vibration and one that creeps out of its housing. At Xinxiang Haishan Machinery we cast and machine flanged bushings to your drawing or a worn sample, matching the original alloy where a replacement is needed.

Design & materials

Flanged bushings are usually specified in tin bronze or aluminium bronze, depending on load, speed and lubrication. Common grades include C93200 (SAE 660) for medium-load, general-purpose service, C93700 where dirt or grit is present, C95400 and C95800 aluminium bronze for higher impact and wear resistance, and C86300 manganese bronze for high-strength applications. The flange diameter, thickness and fillet are machined to suit your housing and retaining method. See the full range of bronze bushing options on our bushing category page.

Typical applications

• Crusher and screen shaft pivots where axial location matters
• Conveyor and bulk material handling idler and pulley hubs
• Pump, valve and hydraulic linkage bushings
• Construction machinery pins and boom joints
• Cement plant and aggregate equipment wear points

Manufacturing & inspection

We produce flanged bushings by centrifugal casting, sand casting or metal mold casting, then finish them with in-house CNC machining to drawing. Centrifugal casting gives a denser wall than static sand casting, which suits bushing stock that will be bored and loaded. Each batch is checked by spectrometer composition analysis and hardness testing in our own laboratory before dispatch. If you are replacing an OEM part, we can reverse-engineer from a worn sample and match the original material. More detail on our processes is available on the manufacturing page.
