Flanged Bronze Pipe Bushing for Shaft Guidance
Cast bronze flanged pipe bushing for shaft guidance, support and friction reduction. Custom made to drawing or sample in tin bronze, aluminum bronze and manganese bronze.
A flanged bronze pipe bushing combines a cylindrical bronze sleeve with an integral flange at one end. The flange locates the bushing axially and provides a bolt-down face, while the bore guides a shaft, rod or piston in straight-line motion. Because the body is cast bronze rather than a thin-walled insert, it carries load, absorbs shock and reduces metal-to-metal contact in the joint.
Design and materials
Bushing geometry is normally defined by bore diameter, outside diameter, flange thickness and bolt-hole pattern. Wall thickness and flange size are matched to the load and to the housing that receives the part. Common alloy choices include C93200 (SAE 660) tin bronze for medium-load guidance, C93700 where dirt or grit is present, C95400 aluminum bronze for higher strength and impact, and C86300 manganese bronze for heavy static loads. The flange face can be machined flat and drilled to the drawing, and oil grooves or lubrication holes can be added where the application calls for them.
Typical applications
- Hydraulic and pneumatic cylinders, where the flange mounts to the cylinder end cap
- Press tools and stamping dies, guiding punches and ejector pins
- Machine tool slides, guide columns and automation linear components
- Pump and valve linkages, and general heavy equipment pivot points
Manufacturing and inspection
Haishan casts these parts by centrifugal, sand or metal mold casting depending on size and quantity, then machines them in-house to the supplied drawing. Centrifugal casting produces a denser wall than sand casting, which suits bushing sections that see continuous sliding contact. Each batch is checked for chemical composition on a spectrometer and for hardness in our own laboratory before shipment. We also reverse-engineer worn bushings from a sample when no drawing is available, matching the original alloy where possible. For related parts, see our bronze bushings and custom casting ranges.
