Crossed roller bearings feature a two-piece outer ring, bolted together to prevent separation during transport and installation. Shaft diameters range from 30 to 250 mm. ... CRB and CRBC are available with shaft diameters as large as 800 mm.

crossed roller slides (also referred to as crossed roller bearings) are linear bearings that use cylindrical rollers—as opposed to balls—to carry a load. The rollers ride between parallel guides in which v-shaped grooves have been ground

 In contrast, crossed-roller bearings that use cylinder-shaped rollers are more accurate and rigid mechanical linear components.
