Bronze Bushing for Slag Remover Machines

Slag remover machines work in some of the harshest conditions in mining and metallurgy: heavy loads, abrasive dust, heat, and limited lubrication access. The bronze bushings in the boom, swing, and cylinder pivot points are wear parts that take continuous sliding contact. When they wear out, the whole machine loses precision and downtime climbs. We cast and machine replacement bushings to match your original dimensions and alloy, so the fit is right the first time.

Design & materials

We select the alloy based on load, speed, and lubrication conditions. Common choices for slag remover bushings include tin bronze such as C93200 (SAE 660) for medium-load sliding contact, and aluminum bronze such as C95400 where impact and abrasion are present. For high-strength pivot points, C86300 manganese bronze is often used. If you can supply the original grade or a worn sample, we match it.

• Cast to your drawing or reverse-engineered from a worn sample
• Centrifugal casting for higher density than sand casting
• In-house CNC machining to final bore and flange dimensions
• Spectrometer composition check and hardness testing on every batch

Typical applications

These bushings are used in slag remover boom pivots, swing bearings, hydraulic cylinder mounts, and conveyor drive points. The same design approach applies to other heavy equipment in mining and quarrying and bulk material handling. If your machine runs in dusty, high-load conditions, a bronze bushing with good embeddability and conformability is usually the right choice.

Manufacturing & inspection

We handle casting and machining in one facility, which keeps tolerances consistent from pour to final cut. Sand casting, centrifugal casting, and metal mold casting are all available depending on part size and quantity. Every bushing is checked for composition and hardness before shipment.
