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 rollers from tilting and grinding each other. 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)Ease of 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)Large axial and radial loads are applied
Because of the roller in the 90 ° V groove rolling surface by interval retainer is vertically to each other
(4)Large savings in 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.
