At Liyuan Drive, we specialize in high-performance slewing bearings, offering single-row ball, double-row ball, and triple-row roller structures. Whether you require standard excavator replacements or fully customized engineering solutions, our factory is equipped to deliver within tight deadlines.
Quality is our baseline—our standard slewing bearings are manufactured to Grade 10 precision, with the flexibility to adjust tolerances for high-demand applications. We utilize premium materials such as 42CrMo and 50Mn, combined with advanced surface induction quenching to reach a raceway hardness of HRC 24-31, ensuring maximum durability and load capacity.
We maintain a permanent inventory of common slewing bearings for major excavator brands, ensuring immediate dispatch. For custom projects, our technical team provides full OEM/ODM support, from initial drawing analysis to final load-testing, ensuring every solution meets your specific project needs.
