XU080430 XU Series Crossed Roller Bearings Size 380x480x26mm

Description With the Crossed roller bearing, cylindrical rollers are arranged crosswise, with each roller perpendicular to the adjacent roller, in a 90°V groove, separated from each other by a spacer retainer.  This design allows just one bearing to receive loads in all directions including, radial, axial and moment loads. Since the Crossed Roller bearingachieves high rigidity and the precision can reach up to P4.P2,despite the minimum possible dimensions of the inner and outer rings,it is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, rotary units of manipulators, precision rotary tables, medical equipment, measuring instruments and IC manufacturing machines Rotation accuracy The spacer retainer fitting among cross-arrayed rollers prevents rollers from skewing and the rotation torque from increasing due to friction between rollers. Unlike conventional types using steel sheet retainers, the crossed roller bearingdoes not cause displacement or locking of rollers and provides a stable rotation torque. Since the inner and outer rings are designed to be separable, the bearing clearance can be adjusted. In addition, highly accurate rotary motion is ensured through adjusting the bearing clearance to provide a preload.   Model number Main dimensions (mm) Weight (kg) Inner ring(d) Outer ring (D) Width XU050077 40 112 22 1.4 XU060094 57 140 26 2.4 XU060111 76.2 145.79 15.87 1.2 XU080120 69 170 30 4 XU080149 101.6 196.85 22.22 3.6 XU120179 124.5 234 35 7 XU120222 140 300 36 12 XU160260 191 329 46 16 XU080264 215.9 311 25.4 6.9 XU160405 336 474 46 25 XU080430 380 480 26 12 XU300515 384 646 86 115
