We are a high-tech enterprise specializing in the R&D, manufacturing, and sales of slewing bearings (also known as rotary bearings). With years of experience in the industry, we are committed to providing global customers with high-load-bearing, high-precision, and long-life bearing solutions. As a leading slewing bearing manufacturer and supplier, we possess complete production lines and advanced heat treatment and grinding equipment, enabling us to mass-produce various standard and non-standard slewing bearings.
Our product series covers various structures including single-row four-point contact ball bearings, double-row eccentric ball bearings, three-row roller bearings, and cross-roller bearings, to meet the complex force requirements under different working conditions—simultaneously bearing axial force, radial force, and overturning moment. We select high-strength alloy steels such as 50Mn and 42CrMo as raw materials. The raceway surface undergoes medium-frequency quenching treatment, achieving a hardness of HRC55-62, with uniform hardened layer depth, ensuring excellent wear resistance and fatigue resistance. All products undergo precision grinding and rigorous online testing, including key indicators such as raceway runout, clearance, and starting torque, ensuring smooth rotation and high installation accuracy.
Our slewing bearings are widely used in construction machinery (such as excavators, cranes, and concrete pump trucks), wind power generation, port machinery, metallurgical equipment, medical equipment, and automated production lines. We also possess strong custom development capabilities, enabling us to quickly provide optimized design and manufacturing solutions based on customer-provided load parameters, installation dimensions, and special operating conditions, helping customers improve overall machine performance. As an ISO9001 certified manufacturer, we consistently adhere to the principle of "Quality First, Service Supreme," earning the long-term trust of domestic and international customers with reliable products and timely technical support.
We welcome inquiries and cooperation from all sectors. We will leverage our professional experience to provide you with the most suitable slewing bearing solutions.
