Custom Pilot Bronze Bushing

A pilot bushing locates and supports a shaft where alignment matters more than load capacity, so the fit, wall thickness and bore finish usually decide how well it performs. We produce custom pilot bronze bushings from your drawing, or reverse-engineer a worn sample when no drawing is available, matching the original alloy where the grade can be identified.

Design and materials

Bronze remains a common choice for pilot and guide bushings because it tolerates marginal lubrication and tends to wear in preference to the shaft. Typical options include C93200 (SAE 660) tin bronze for general duty, C93700 where dirt or grit is present, and C95400 aluminum bronze or C86300 manganese bronze where higher strength is needed. We also cast C90700 tin bronze, C51100 phosphor bronze and ZCuSn10P1, and can supply custom copper alloys to a specified composition. Bore, chamfer, oil groove and flange details are machined to your drawing.

Typical applications

• Pilot and guide bushings in crushers and vibrating screens
• Pump, valve and hydraulic cylinder guide components
• Pivot and linkage bushings on construction and mining equipment
• Replacement bushings for bulk material handling and conveyor drives

Manufacturing and inspection

We combine casting and machining in one workshop, using centrifugal casting, sand casting or metal mold casting depending on size and quantity. Centrifugal casting gives denser wall sections than sand casting in many round parts. Each batch is checked for composition on a spectrometer and for hardness in our own laboratory before machining, and finished parts are inspected against the drawing. See our centrifugal casting process and quality control steps for details.
