In the cross roller bearing, the cylindrical rollers are arranged perpendicular to each other through the spacer on the 90° V-groove rolling surface. This design allows the cross roller bearing to withstand loads in all directions, such as radial loads, axial loads, and moment loads.
At the same time, the size of the inner and outer rings is minimized, especially the ultra-thin form is close to the limit of small size, and has high rigidity, so it is suitable for a wide range of uses such as the joints or rotating parts of industrial robots, the rotary table of the machining center, the rotating part of the robot, the precision rotary table, medical equipment, measuring instruments, IC manufacturing equipment, etc.
Thin‑wall ball bearing (also known as thin section ball bearing) is a specialized bearing designed for space‑limited, lightweight, and high‑precision applications. Featuring a fixed wall thickness, these bearings deliver low friction, quiet operation, and high rigidity. With contact styles such as radial, angular contact, and four‑point contact, thin‑section bearings support multiple load types while offering compact size, high performance, and design flexibility. Ideal for robotics, aerospace, medical devices, semiconductors, and precision instruments.
Slewing bearings are large rolling bearings with a strong comprehensive load carrying capacity, capable of withstanding radial loads, axial loads and tilting moments at the same time. Its structural features include hardened raceways, high rigidity cage design, internal or external tooth drive interface, and a complete sealing and lubrication system. This makes slewing bearings widely used in cranes, wind power generation, harbor equipment and other fields. Different types such as four-point contact ball type, crossed roller type, and three-row roller type each have the advantage of high precision, compactness or high dynamic load carrying capacity. In terms of installation and maintenance, the slewing bearing is equipped with mounting holes and lubrication holes, which can facilitate daily lubrication and maintenance and prolong service life.
