Double Flanged Bronze Bushing for Heavy Equipment

A double flanged bronze bushing carries two integral flanges, one at each end of the sleeve. This lets a single component locate the shaft axially in both directions while still carrying radial load, which is useful where space is tight and separate thrust washers are difficult to fit. DASHAN casts and machines these bushings to drawing or to a worn sample, matching the alloy and dimensions of the original part.

Design and materials

Flange diameter, flange thickness, bore, length and lubrication grooves are all made to the customer's drawing. Common alloys for this type of bushing include C93200 (SAE 660) tin bronze for general medium-load service, C93700 where dirt or grit is present, and C95400 aluminium bronze where higher strength and impact resistance are needed. C86300 manganese bronze is also used for heavily loaded, slow-moving joints. The alloy is selected against the actual load, speed and lubrication conditions rather than by a single fixed rule.

• Two integral flanges for axial location and thrust support
• Bore, length and flange sizes machined to drawing
• Oil grooves, grease holes and chamfers as required
• Alloy matched to the original part or specified by the customer

Typical applications

Double flanged bushings are usually found in pivot points, linkage joints, crusher and screen mechanisms, conveyor and bulk handling equipment, and pump or valve assemblies where axial movement must be limited. They are common in mining and quarrying equipment and in aggregates and crushing plants.

Manufacturing and inspection

We use centrifugal casting, sand casting and metal mold casting depending on part size and quantity, followed by in-house CNC machining. Each batch is checked with spectrometer composition analysis and hardness testing before shipment. Castings range from 20 mm to 6000 mm in diameter and 0.1 to 15000 kg, with each part made to order.
