The raceway structure of the bearing is different from the common single raceway. It is a combination structure of multiple raceways. One set of bearings can meet the requirements of the turntable to bear the combined load. The bearing is arranged with mounting holes, which makes the installation extremely convenient, greatly simplifies the structure of the turntable, and reduces the design, installation, maintenance and cost. It is used in CNC turntables, five-axis machining centers, turning and milling composite machining centers, gear processing equipment, precision grinders, precision measurement and control equipment, etc.

Crossed roller bearings are also called cross-crossed roller bearings. The rolling elements are generally arranged crosswise on the raceway by cylindrical rollers or tapered rollers. This arrangement allows a single bearing to withstand axial loads, radial loads and overturning moments while ensuring the miniaturization of the bearing's overall dimensions. It is used in direct-drive motors, five-axis machining centers, robots, medical equipment, fourth-axis turntables, milling heads, high-speed vertical lathes, etc.

Robot bearings are divided into industrial robot bearings and humanoid robot bearings, mainly including cross roller bearings and flexible bearings for harmonic reducers; angular contact ball bearings and tapered roller bearings for RV reducers; thin-walled cross roller bearings for planetary reducers; and cross roller bearings for robot support and rotating parts.
