Bronze Split Bearing Shells for Heavy Equipment

A split bearing shell is the replaceable half-cylinder that carries the shaft in a sliding bearing. Because it is split, it can be fitted around a shaft without dismantling the whole assembly, which is why it is common on crushers, mills, pumps and other heavy equipment where downtime matters. We cast and machine split bronze bearing shells to your drawing or to a worn sample, matching the original alloy where the grade is known.

Design & materials

Split shells are supplied in two halves, with or without oil grooves, and are normally a clearance fit on the journal. Alloy choice follows the duty: C93200 (SAE 660) tin bronze is a general-purpose bearing grade for medium loads, C93700 suits dirtier or poorly lubricated conditions, C95400 and C95800 aluminum bronze are chosen where impact and abrasion are present, and C86300 manganese bronze is used for high-strength applications. We melt our own heats, so if you can supply a grade we can cast it.

Typical applications

• Crusher and mill bearing shells
• Pump, valve and hydraulic bearing housings
• Construction and bulk material handling equipment
• Replacement of OEM split bearings

Manufacturing & inspection

We select the casting method to suit the part: centrifugal casting for dense, porosity-controlled cylindrical shells, sand casting for larger or complex shapes, and metal mold casting for repeatable smaller parts. Machining is done in-house to your drawing, followed by spectrometer composition checks and hardness testing in our own laboratory. Tell us the equipment, the shaft size and the working conditions, and we will recommend a grade and a casting route. Send your drawing or a worn sample for a free evaluation.
