Product Description
Cross Roller Bearing , 20x70x12mm Rated Load C : 7.35KN , C0 : 8.35KN
Product description:
Cross roller bearing is a type of bearing where cylindrical rollers are vertically arranged in a cross pattern between the inner and outer rings of the bearing. The rollers are in line contact with the raceway and have good rigidity. The elastic deformation of the bearing under load is very small, and it can withstand both radial load, axial load, and torque load. It is particularly suitable for situations that require high rigidity and high rotational accuracy.
The size of the inner and outer rings is minimized, especially the extremely thin type, which is a small size that is close to the limit and has high rigidity. Using this type of bearing can simplify the structural design of the shaft system. So it is most suitable for the joint or rotating parts of industrial robots, rotating workbenches of machining centers, robotic arm rotating parts, precision rotating workbenches, medical devices, measuring instruments, IC manufacturing and loading fields, and has been well applied.
