Gantry Crane Slewing Ring - High-Precision Industrial Bearing Solutions
When you need reliable lifting equipment, the Gantry Crane Slewing Ring becomes your most critical component. This specialized bearing supports heavy loads while enabling smooth rotational movement in your crane operations. At Luoyang Heng Guan Bearing Technology Co.,Ltd, we manufacture these essential components using premium 42CrMo alloy steel that meets strict EU standards. Our three-row roller design ensures superior performance across bridge cranes, gantry cranes, and tower cranes. You get exceptional structural rigidity, precise motion control, and long-lasting reliability for your industrial lifting applications.
What Makes Our Slewing Rings Special?
Your crane operations demand precision and durability. Our slewing rings deliver both through advanced engineering and quality materials.
Premium Construction Materials
We use high-strength 50Mn and 42CrMo alloy steels for ring construction. The rolling elements feature GCr15SiMn bearing steel for maximum durability. This combination provides excellent resistance to wear and fatigue under heavy loads.
Precision Engineering
Our three-row roller configuration distributes loads evenly across axial, radial, and moment forces. This design reduces stress concentrations and extends bearing life significantly.
Flexible Size Options
Standard dimensions of 862×730×145mm fit most applications. However, we process custom sizes from 50mm to 10,000mm diameter. Your specific requirements guide our manufacturing approach
