Large Diameter Bronze Bushing for Heavy Equipment

Large diameter bronze bushings carry the highest loads in mining and heavy equipment, where shaft deflection, shock loading and limited lubrication all shorten service life. Xinxiang Haishan Machinery casts and machines these bushings in one workshop, so a single supplier controls wall thickness, concentricity and alloy quality from melt to finished bore.

Design and materials

We select the alloy to match load, speed and environment rather than forcing one grade onto every application. Tin bronzes such as C93200 (SAE 660) and C90700 offer good conformability for moderate loads, while aluminium bronzes like C95400 and C95800 and manganese bronze C86300 suit high-load, shock-prone positions. Large castings can also be poured to Chinese grades such as ZCuSn10P1 or to a customer-specified chemistry.

• Castings from 20 mm to 6000 mm diameter, 0.1-15000 kg
• Centrifugal casting for dense, sound walls on ring-shaped parts
• Sand and metal mold casting for complex or heavy sections
• OEM replacement, reverse-engineered from a worn sample
• Machining to drawing with controlled bore and flange tolerances

Typical applications

These bushings are used in crusher eccentric and frame positions, mill trunnions, pump and valve bearings, and pivot points on construction and bulk handling equipment. See our bronze bushing range and mining industry page for related parts and duty conditions.

Manufacturing and inspection

Melting is followed by spectrometer analysis before pouring, so the chemistry is confirmed while the metal is still in the furnace. Centrifugal casting improves density and mechanical properties compared with static sand casting. After casting, parts are CNC machined and checked with hardness testing and dimensional inspection in our own laboratory before packing.
