Crossed Roller Bearings

Crossed Roller Bearings
Introduce
In cross roller bearing, cylindrical roller in the 90°V groove rolling through the interval on the surface of retainer are vertically arranged to each other, So it can bear radial load, axial load and torque load, etc in all the direction of the load. The dimension of the inner and outer rings is a minimum to miniaturization, especially extremely thin type is close to the limit of small size, and high rigidity, So it suitable for industrial robot joints department or rotary department, mechanical processing center of the rotary worktable, manipulator rotary department, precision rotary worktable, medical instrument, measuring instruments and IC manufacturing machines.
Features of Crossed Roller Bearings
01
Excellent Rotation Accuracy
The roller in vertically equipped with interval retainer, to prevent roller from skewing and rubbing against each other, to prevent rotation torque from increasing. In addition, compared with the previous use iron plate type of retainer, it does not cause contact of roller or locked. At the same time, the inner and outer rings are designed to be separable, the bearing clearance can be adjusted, even if the preload can be applied, it also can obtain stable rotation motion.
02
Easy Operating
The inner ring and outer rings separated, are fixed together after being installed with rollers and spacers. Therefore, when installing the cross roller bearing, the operation is simple.
03
Prevent Roller Tilt
Due to separation retainer, roller loads are kept in the correct position, to prevent roller from skewing and rubbing against each other, to prevent rotation torque from increasing, which could obtain stable rotating performance.
04
Big Load Capacity
Compared with the previously take keep shape type, because of the roller effective contact length is longer, so the load resistant capacity were greatly improved. At the same time, the previous retainer compared with interval retainer, which is easy to cause the roller tilt or rotate structure is not smooth.
05
Greatly Improves the Rigidity (3~4 times)
For roller are vertially arranged together, and use the double column thin compared with the form of angular contact ball bearing, only use one bearing can bear the load of all directions, and rigidness were increased to 3~4 times.
