Product Short Description

Cylindrical roller bearings are rolling bearings composed of a disc-shaped roller and a cylinder, which are mainly used to bear radial loads, but can also bear axial loads and torsional loads. The rollers of cylindrical roller bearings are arranged in parallel, and there is a spacer between the rollers, which can effectively avoid the inclination of the rollers or the friction between the rollers, and reduce the increase of rotating torque. Among them, the double row cylindrical roller bearing has two structures: cylindrical inner hole and conical inner hole (bearing post code plus). This kind of bearing has the advantages of compact structure, large rigidity, large bearing capacity, small deformation after load, etc., especially suitable for machine tool support. The conical inner hole can also play a role in micro-adjusting the clearance, and can simplify the structure of the positioning device, convenient installation and disassembly.
