XR882055 Tapered Cross Roller Bearing 901.7x1117.6x82.55mm 

A double outer race and two inner rings, with rollers spaced by nylon separators,it Designed to offer the highest levels of rotation accuracy and rigidity while conserving space and saving material costs.

Timken Standard XR/JXR serie The bearing features two sets of races and rollers brought together at right angles with alternate rollers facing in opposite directions. The height of the cross section is more or less sam with the single row bearing,so it can save space and bearing housing material.this series bearings with high precision,high rigidity and able to withstand higher overturning moments, is ideal for the table bearing of machine tools, including vertical boring and grinding machines etc.
