Flanged Bronze Guide Bushing for Shaft Guidance

A flanged guide bushing combines a plain bronze sleeve with an integral shoulder, so the part can be seated against a housing face and held against axial movement without a separate collar. In mining and heavy equipment, this style is often chosen where a rod, piston or shaft needs a defined locating point as well as a low-friction running surface. The flange also gives maintenance teams a clear reference for installation depth during rebuilds.

Design and materials

Bronze is selected for its bearing behaviour rather than its strength alone: it tolerates edge loading, runs quietly against steel and resists corrosion in wet or dusty service. Common choices include C93200 (SAE 660) tin bronze for general medium-load guidance, C95400 aluminium bronze where impact and abrasion are present, and C86300 manganese bronze for higher-strength applications. Where lubrication is difficult to maintain, a graphite-plugged variant can be cast instead. Flange diameter, bore, length and oil grooves are all produced to the customer's drawing or a worn sample.

Typical applications

• Hydraulic and pneumatic cylinder rod guidance
• Press tooling, punch and ejector pin guidance
• Machine tool slides and automated linear motion parts
• Pivot and linkage points on crushers and conveyors

Manufacturing and inspection

We cast in-house by centrifugal, sand or metal mould methods depending on size and quantity, then machine on CNC equipment to the drawing's tolerances. Each batch is checked for composition on a spectrometer and for hardness in our own laboratory. See our bronze bushing range and centrifugal casting process for related options.
