Product Details

　　Cross roller bearings, also known as crossed roller bearings or crossed roller slewing bearings, typically feature cylindrical or tapered rollers arranged in a cross pattern on a single raceway, with spacers or isolators between the rollers. They offer high rotational precision, large load capacity, compact dimensions, high rotational speed, and rigidity, making them suitable for a wide range of applications with superior advantages over other types of bearings.

　　The unique cross arrangement of rollers in these bearings allows them to withstand axial loads, radial loads, and overturning moments in all directions. Compared to traditional bearing structures, the rigidity is increased by 3-4 times. Moreover, the outer dimensions of this series of bearings are maximally minimized, especially the ultra-thin structure which approaches the limit of miniaturization, while maintaining high rigidity. Therefore, they are suitable for use in industrial robot joints or rotating parts, rotary worktables of machining centers, rotating parts of mechanical arms, precision rotary worktables, turntables, medical instruments, and other applications.

　　Cross tapered roller bearings utilize a large cone angle and tapered geometry to increase the effective span of the bearing assembly while saving space and material costs. Consequently, they have higher resistance to overturning moments, higher rotational precision, and maximum speed, making them the ideal choice for bearing turntables on high-speed vertical lathes, vertical gear hobbing machines, and vertical grinders.
