The features of cross roller bearings
Cross roller bearing, by dividing the inner ring or outer ring, after loading roller and retainer interval, and cross roller bearing ring fixed together, in order to prevent the separation of each other, so the installation of cross roller bearing ring when the operation is simple.
Because of the roller for cross array, so only 1 set of cross roller bearing ring can bear the load of every direction, compared with the traditional model, rigid 3 ~ 4 times.
At the same time, because of the cross roller bearing inner ring or outer ring is two integral structure, bearing clearance can be adjusted, even if be preloading, also can get high precision rotary motion.
1. have excellent rotation accuracy
The internal structure of crossed roller bearings by roller are arranged 90 ° vertically cross each other,
Equipped with interval between roller holder or isolation block, can prevent tilt to friction between the roller of roller.
In addition, not happen roller side contact phenomenon or lock phenomenon;
For internal and external ring is integral structure at the same time, the gap can be adjusted, even if be exerted pressure, also can get high precision rotary motion.
2 .is a simple installation
Is divided into two parts of the outer or inner ring, after loading roller and retainer are fixed together, so the operation when installation is very simple.
3. bear the larger axial and radial load
Because of the roller in the 90 ° V groove rolling surface by interval retainer is vertically to each other.
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. High speed capability
6. Reduce the axial length and the processing cost, thermal expansion leads to the change of the geometry size is limited
7. Use nylon spacer, moment of inertia is low, low starting torque, easy to control the Angle degree
8. Optimization of preloaded force, stiffness big, high precision guide roller operations
9. Offer good resistance to impact and surface carburizing steel anti-wear ability
10. Simple but abundant lubrication
