Roller Support Bearings are designed for guides of rectilinear movement with a large stroke length of the moving units at speeds of up to 10 m/min. Guides with roller bearings have high stiness, low resistance to movement (demonstrated friction coe cient 0.002-0.004), high positioning accuracy in the absence of jumps at low feeds, high durability with intensive work at high speeds. The support structure is a rigid thin guide around which rolling bodies (rollers) are run around in a closed path. Rollers are kept from falling out by clips and springs.
