Timken® XR820060-903A5 Precision Level 3 TXR Style Crossed Roller Bearing, 22.8346 in Dia Bore, 29.9213 in OD, 3.15 in W, 48400 lb Radial/52500 lb Axial Load
Precision crossed roller bearings (TXR) are designed to offer the highest levels of rotational accuracy and rigidity while conserving space and saving material costs. The bearing features two sets of races and rollers brought together at right angles with alternate rollers facing in opposite directions. This allows two half-rows of rollers to fit into the space of one. The steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself. Able to withstand high overturning moments, the crossed roller bearing is ideal for the table bearing of machine tools, including vertical boring and grinding machines. It is uniquely suited to many other pivot and pedestal applications where space is limited or the lowest possible center of gravity of a rotating mass is required.
