Import Eccentric Bushing For Metso Gp 300 — Buy in wholesale FOB from Supplier in China

The Eccentric Bushing for Metso GP 300 is a precision-machined component designed to interface with the main shaft and eccentric sleeve assembly in gyratory crushers. It is manufactured to exact dimensional tolerances matching the original Metso GP 300 specifications, with an outer diameter of 185 mm and an inner bore of 120 mm, as confirmed by the supplier's technical drawings. The bushing features a hardened surface layer to resist abrasion under continuous high-load operation in crushing circuits.

This component is typically forged from alloy steel with a carbon content between 0.45% and 0.55%, followed by induction hardening to achieve a surface hardness of 58 to 62 HRC, a standard practice for such bushings in the mining equipment sector. The internal geometry is precision-ground to maintain concentricity within 0.05 mm, ensuring smooth rotational alignment. While the listing does not specify the exact alloy grade, the material profile aligns with typical ASTM A29 4140 or equivalent European 42CrMo4 standards used in heavy-duty crusher bushings.

These bushings are primarily purchased by mining equipment maintenance departments, aggregate plant operators, and OEM service providers across Southeast Asia, Africa, and Latin America. They are supplied in single-unit quantities or bulk lots, with packaging in wooden crates lined with rust-inhibiting paper. Trade terms offered include FOB Xingang or CIF destination port, with lead times typically ranging from 25 to 40 days after order confirmation. Buyers should verify compatibility with their specific GP 300 model variant before ordering.

Xinxiang Haishan Machinery Co., Ltd. is a manufacturer based in Hui County, Henan Province, China, specialising in wear parts for crushing and screening equipment. The company is verified as a harbor-tier supplier on the platform, indicating active engagement in export documentation and logistics coordination. The listing confirms no direct affiliation with Metso or OEM production, but the supplier states technical alignment with original equipment dimensions and material profiles.

The supplier's facility has machining capacity for large forged components and performs heat treatment in-house. There is no public information on company size, annual revenue, or employee count. The supplier does not list certifications such as ISO 9001 or material test reports in the listing, and response rates are not available. Buyers should request documented material certificates and dimensional inspection reports prior to order placement.
