XR series of cross-tapered roller bearings designed

XR series of cross-tapered roller bearings designed to provide high accuracy and rigidity of rotation in a smaller space, dramatically saving material costs. These bearings are the two rotary table bearing raceways and rollers are mounted together cross at right angles, adjacent roller in the opposite direction, is mounted between the roller and roller isolation block, the roller is also equipped with support pads this allows the rollers to fit into the two half-columns in the same space. Angle and taper bearing geometry makes bearings effective span than the actual width of the bearing itself several times.
XR series Four-Row Cylindrical Roller Bearing for high-speed machine tool applications such as vertical boring and vertical grinders. Many are also particularly suitable for the limited space, high precision rotating equipment.
