Linear bearing and guides for smooth motion system performance

Cross-roller bearings are good for high-precision appliions. Unlike the balls in ballscrews, cross-rollers do not recirculate. This property reduces fluctuations in frictional resistance. Static and dynamic frictional resistance are nearly the same. The drawback is that crossed roller bearings are limited in travel to the region with the

The Basics of Crossed Roller Bearings | Nippon Bearing

Jan 17, 2018· A crossed roller bearing, also called a crossed roller slideway, is effectively two sets of bearings and races coined at right angles to each other. Cylindrical bearings or rollers mount along the length of a rail in a carriage. The rollers are held in place with a cage, preventing roller-to-roller contact, which increases friction and wear.
