Double Row Cylindrical Roller Bearings

Spherical Roller Bearings

Cylindrical roller bearings are separable bearings. The inner ring, outer ring and rollers are in line contact, offering a low friction coefficient and high limiting speed. Double row cylindrical roller bearings feature a compact structure, high rigidity, strong load-carrying capacity and low deformation under load, making them suitable for machine tool spindle supports. Cylindrical roller bearings are widely used in heavy-duty machinery such as cold and hot rolling mills. The basic radial clearance of single row cylindrical roller bearings is normal clearance, and other clearance grades such as C3 and C4 can be selected according to actual requirements.
