Crossed cylindrical roller bearing can be widely used in machine tool precision rotary indexing table, vertical and horizontal boring machine, vertical grinding machine, rotary surface grinding machine, large gear hobbing machine, guns and rotary table, large radio and optical telescopes, rotating camera, steering pivot and continuous casting machine, highly restricted pivot microscope platform, pole center axis, bogie, welding stents, turning assembly fixture, industrial robots, precision rotary worktable, medical apparatus and instruments, measuring instruments, IC manufacturing equipment and so on.
1. Excellent rotation accuracy
Crossed roller bearings
The internal structure of crossed roller bearings by roller are arranged 90 ° vertically cross each other, with intervals between roller device or isolation, can prevent roller friction between roller tilt goods, effectively prevent the rotation torque increases.In addition, there will be no roller side contact or locking phenomenon;
Non-standard cross roller bearings can also achieve high precision rotational motion even when preloaded because the inner and outer rings are segmented and the clearance can be adjusted.
2. Easy operation and installation
The outer ring or inner ring, which is divided into two parts, is fixed together after the rollers and retainers are loaded, so the installation operation is very simple.
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 crossed roller bearings can bear larger radial load, axial load and torque load, etc. All the direction of the load.
4. Greatly save installation space
Crossed roller bearings 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.
