In order to meet different needs of acustomers,Luoyang Jiayu design and manufacture Precision crossed roller bearings to offer the highest levels of rotational accuracy and rigidity while conserving space and saving material costs. <\/p>\n\n\n\n

The bearing has the thfeatures that two sets of races and rollers are 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.<\/p>\n\n\n\n

The steep-angle, tapered geometry results in a total effective bearing spread much greater than the width of the bearing itself. The special structure help it to withstand high overturning moments, so crossed roller bearing is ideal for the table bearing of machine tools, including vertical boring and grinding machines.<\/p>\n\n\n\n

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. <\/p>\n\n\n\n
