Product Description

Double row cylindrical roller bearings have two structures: cylindrical inner hole and conical inner hole (bearing post code plus K). Column cylindrical roller bearing has the advantages of compact structure, high rigidity, large bearing capacity and small deformation after loading. The conical inner hole can also slightly adjust the clearance, simplify the structure of the positioning device and facilitate installation and disassembly.
