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.
