Single-Row Ball Slewing Ring

Single-Row Ball Slewing Ring features compact structure, light weight and small overall dimension. It can bear axial load, radial load and overturning moment simultaneously. With flexible rotation and high cost performance, it is the ideal economical choice for light to medium load conditions. Widely used in tower cranes, truck cranes, aerial work platforms, mini excavators and general industrial rotary equipment.

02.

Crossed Roller Slewing Ring

Crossed Roller Slewing Ring is arranged with cylindrical rollers in cross configuration. It achieves high rotational accuracy, ultra-high rigidity and precise positioning. The structure enables it to bear axial, radial and overturning loads in all directions with small mounting size. It features compact layout, zero clearance, smooth operation and strong anti-tilting capability. Widely used for CNC machine rotary tables, automation equipment, precision machinery and robotic arms.

03.

Three-Row Roller Slewing Ring

Three-Row Roller Slewing Ring is the heavy-duty type with three-row roller structure. It has ultra-large load capacity, supreme rigidity and strong impact resistance. Separately designed to bear axial load, radial load and overturning moment independently, it features rational force bearing structure and extremely high bearing capacity. It is specially customized for super heavy load working conditions, widely used in large excavators, mining machinery, wind power equipment and large port hoisting machinery.

04.

Double-Row Ball Slewing Ring

Double-Row Ball Slewing Ring adopts double-row ball structure design, with higher load capacity and better rigidity than single-row type. It features reasonable force distribution, stable rotation and excellent comprehensive bearing performance. This slewing ring can withstand larger axial and radial loads as well as overturning moment, suitable for medium to heavy load working conditions. It is widely applied in large cranes, port machinery, construction machinery and heavy-duty industrial rotary tables.

Giving Our New 3-Meter Grinder Its Final Look!
Another exciting update from our new factory! Our brand-new 3-meter grinding machine is taking its final shape—the team is currently installing its heavy-duty sheet metal enclosure (the protective outer shell). While the internal precision testing is complete, this sturdy outer shell is just as important. It keeps the workspace clean, ensures top safety for our team, and protects the machine's high-precision parts. Seeing this giant machine go from bare steel to a fully finished, professional workstation makes us incredibly proud of our nearly 20 years of growth. We are just a few steps away from pressing the "Start" button on this new production line. Stay tuned for more updates!
