cylindrical rollers are commonly used in joint bearings where the load capacity and wear resistance of the bearing are critical factors. The cylindrical rollers can be arranged in a variety of configurations, such as parallel or crossed, to suit the application and the desired load-bearing capacity.
we are professional manufacture of bearing rollers and cylindrical needle rollers. we produce rollers of diameter 0.5 mm to 60 mm. the rollers could satisfy the request of DIN 5402 G2 rollers.

crossed roller bearing is one of the commonly used robot bearings, it is a special type of bearing with outer ring rotation and inner ring division. due to its special structure, it can bear radial load, axial load and moment load and other multi-directional load. the size of crossed roller bearings can be miniaturized according to the requirements of the equipment, and the extremely thin form of bearings is close to the limit of the small size, it has high rigidity, and the accuracy can reach P5, P4, P2 level. crossed roller bearings are often used in joints and rotating parts of industrial robots, rotary tables of machining centers, hospital equipment, military, etc. they are available in RA, RB, RU, CRBH, SX, etc
