Import Best Price Bronze Bushings For Cone Crushers — Buy in wholesale FOB from Supplier in China

Bronze bushings for cone crushers from Xinxiang Haishan Machinery Co., Ltd. are precision wear components that serve as critical bearings between the eccentric assembly and the crusher frame, absorbing radial and axial loads during crushing operations. These components are cast from high-lead tin bronze alloys, with typical material grades including C90700 (SAE 65) or C93200 (SAE 660) offering excellent anti-friction properties and resistance to galling under slow-speed, high-load conditions. The supplier indicates these bushings are engineered for heavy-duty mining and aggregate applications, with custom sizing available to match specific crusher models from major manufacturers.

The material composition is central to bushing performance: standard tin bronze contains 10-12% tin with 2-4% lead for machinability and embeddability, while aluminium bronze variants offer superior strength for newer high-speed crusher designs. Wall thickness, bore diameter and overall length must match OEM tolerances, typically within 0.025-0.05 mm for press-fit applications, to prevent premature failure from fretting or oil starvation. Surface finish requirements of 1.6-3.2 Ra micrometres on the bore are standard to maintain hydrodynamic lubrication film integrity. Xinxiang Haishan Machinery notes that custom dimensions are available, though buyers should supply crusher model numbers or worn sample measurements for accurate replication.

Primary buyers include quarry operators, mining contractors, and aggregate processing plants maintaining Nordberg, Metso, Sandvik and Symons cone crusher fleets. These bushings see service in the spider bushing, eccentric bushing, and bottom shell bushing positions, each subject to different load profiles and wear rates. Replacement intervals vary from 6-18 months depending on feed abrasiveness, crusher CSS setting, and lubrication system condition. For sourcing, buyers should confirm whether Xinxiang Haishan Machinery offers centrifugal casting or static sand casting, as centrifugal methods yield denser grain structure and longer service life in critical applications.

Xinxiang Haishan Machinery Co., Ltd. is located at No. 66 Chengbei Street, Hui County, Xinxiang City, Henan Province, China, a region with established foundry and heavy machinery manufacturing infrastructure. The supplier holds an imported tier classification with harbor trust tier status, though the listing provides no response rate or average response time data. Buyers should note that zero percent response rate and zero hours average response in the available data suggest limited engagement history on this platform, making direct contact verification essential before placing orders.

The company specialises in bronze bushings and wear components for cone crushers, offering custom dimension services based on equipment model numbers or physical samples. No information is provided regarding factory size, annual output, quality certification scope, or export experience to specific markets. The supplier does not list specific clientele, revenue figures, or years in operation. Buyers are advised to request ISO 9001 or equivalent quality system documentation, material test certificates with spectrographic analysis, and reference installations before committing to volume orders.
