Product Description

Main features:
have excellent rotating accuracy, cross roller bearing internal structure of the roller is 90 ° perpendicular cross array (which is also cross roller bearing the name of the origin), with intervals between roller holder or the isolation piece, can prevent roller friction between roller tilt goods, effectively prevent the rotation torque increases. This cross cylindrical roller bearing has been included in the fast and easy optimization, in addition, there will be no roller side contact or lock phenomenon; At the same time, because the standard type of cross roller bearing inner and outer rings are split structure, clearance can be adjusted, even if the pressure is applied, can also obtain high precision rotation movement.





Main features:

1, have excellent rotating accuracy, cross roller bearing internal structure of the roller is 90 ° perpendicular cross array (which is also cross roller bearing the name of the origin), with intervals between roller holder or the isolation piece, can prevent roller friction between roller tilt goods, effectively prevent the rotation torque increases. This cross cylindrical roller bearing has been included in the fast and easy optimization, in addition, there will be no roller side contact or lock phenomenon; At the same time, because the standard type of cross roller bearing inner and outer rings are split structure, clearance can be adjusted, even if the pressure is applied, can also obtain high precision rotation movement.

2, operation and installation of simplified standard type cross roller bearing is divided into two parts of the outer ring or the inner ring, after loading the roller and the holder, is fixed together, the installation can be fine tuning connection bolts and fixed flange to achieve the ideal load state, so the installation operation is very simple.

3, bear a large axial and radial load 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 appropriate and joints of the industrial robot parts or rotating parts, machinery processing center of the rotary worktable, manipulator rotary department, precision rotary worktable, medical instruments, measuring instruments, such as IC manufacturing equipment widely used.
