The intersected roller bearings are easy to operate when the intersected roller bearings are installed after the intersected inner or outer rings are loaded into the roller and spacer and are fixed with the intersected roller bearings to prevent separation from each other. As the rollers are intersected, only one set of intersecting roller shaft ring can bear the load in all directions. Compared with the traditional model, the rigidity is improved by 3~4 times. At the same time, because the inner ring or outer ring of the cross-roller bearing is a two-segment structure, the bearing clearance can be adjusted, and the high precision rotary motion can be obtained even when the preload is applied.

2.Product advantages



 (1)Excellent rotation accuracy
The internal structure of crossed roller bearings by roller are arranged 90 ° vertically cross each other,
A space retainer or isolation block is installed between the rollers to prevent the inclination of the rollers from grinding each other, effectively preventing the increase of rotary torque. In addition, the party will not have roller contact or lock phenomenon; At the same time, because the inner and outer rings are segmented, the clearance can be adjusted, and even if the preloading is applied, the high-precision rotary motion can be obtained.
(2)Simplified operation and installation
The outer or inner ring, which is divided into two parts, is fixed together after loading the roller and the retainer, so it is easy to operate during installation.
(3)Bear large axial and radial loads
Because of the roller in the 90 ° V groove rolling surface by interval retainer is perpendicular arrangement, this design makes cross roller bearings can bear larger radial load, axial load and torque load, etc. All the direction of the load.
(4)Significantly save installation space
Cross roller bearing inner and outer ring size is minimal miniaturization, especially ultra-thin structure is close to the limit of small size, and high rigidity, so the most suitable for the joints of the industrial robot parts or rotating parts, machinery processing center of the rotary worktable, mechanical rotary department, precision rotary worktable, medical instruments, measuring instruments, such as IC manufacturing equipment widely used.
(5) Reduce shaft length and processing cost, and the change of geometric size is limited due to thermal expansion
(6)Using nylon divider, low rotary inertia, low starting torque, easy to control Angle indexing
(7)Optimize the pre-tightening force, stiffness, high precision guide roller operation
(8)Simple but well lubricated
