About Zhejiang Hengli Powder Metallurgy Co., Ltd.
Zhejiang Hengli Powder Metallurgy Co., Ltd. specializes in the R&D, manufacture, and marketing of alloy self-lubricating bearings (bushing blocks) for heavy construction machinery applications. Based in Jinhua, the company focuses on components designed for low-speed, heavy-load working conditions commonly found in excavators, loaders, and related equipment.
Guided by foreign experts, the R&D team has developed a series of alloy self-lubricating bearings positioned to replace imported components. Through extensive trials and repeated use by well-known domestic and international brands, these products have demonstrated performance comparable to imported parts.
The bearings are produced through a powder metallurgy route using metal powders such as Fe, Cu, C, and Mo. After sintering and subsequent processing, the porous structure is impregnated with lubricant under controlled temperature to support self-lubrication in service, helping reduce dry friction and protect critical assemblies such as arm bodies and hydraulic cylinders.
With ongoing improvement of its automatic production line, the company offers a broad specification range and the capacity to support big and mid-sized construction machinery manufacturers with stable supply and continuous innovation.
