Cylindrical Bronze Bushings for Mining & Heavy Equipment
Custom cylindrical bronze bushings cast and machined in-house to your drawing or worn sample, in tin bronze, aluminum bronze and manganese bronze grades.
Cylindrical bronze bushings are the plain bearing workhorses of mining and heavy equipment, carrying radial loads on crusher shafts, pump drives, conveyor pulleys and hydraulic linkages. A straight (non-flanged) sleeve is often the simplest and most reliable answer where the housing already provides axial location. We cast and machine these sleeves to your drawing, or reverse-engineer them from a worn sample when drawings are no longer available.
Design & materials
Alloy choice drives performance more than any other single decision. Tin bronze such as C93200 (SAE 660) is a common general-purpose grade for moderate loads and steady lubrication. Where shock and abrasive dust dominate, aluminum bronze C95400 and manganese bronze C86300 are frequently specified for their higher strength. Phosphor bronze C51100 suits applications needing better fatigue resistance. We can also match an original OEM grade or cast to a customer-supplied specification.
- Straight sleeve design, machined to drawing tolerances
- Centrifugal, sand or metal mold casting selected per part geometry
- Solid or cored bores, oil grooves and lubrication holes as required
- Custom alloy formulation to match original material
Typical applications
Straight bronze bushings appear across our mining and aggregates equipment programs — crusher eccentric and frame positions, vibrating screen shafts, pump bearing housings, and pivot points on loaders and excavators. In dusty or poorly lubricated locations, a graphite-plugged variant may be worth discussing.
Manufacturing & inspection
Casting and machining are handled under one roof, which shortens the loop between foundry and final dimensions. Centrifugal casting is used where a denser wall structure is beneficial. Each batch is checked with spectrometer composition analysis and hardness testing in our own laboratory before machining, and finished parts are verified against the drawing.
