Linear roller bearing assembly

摘要

The arrangement has two parts (10, 20) longitudinally movable with respect to each other via at least one series of roller bearings, a positive controller for the roller bodies (5) containing a gearwheel type element (32) for engaging in a rack type region (22) on at least one of the parts and surface roughness in at least recesses of the rack type region with a roughness coefficient of less than 0.4 microns, especially less than 0.3 microns.
