SRB Bearings combined needle and roller bearings for ball screw support.
Advanced technology allows to reach very high speeds while securing the precision level requested for each application. UNITEC SRB combined bearings enhance static and dynamic stiffness of your ball screws.
SRB Bearings are needle roller bearings with an outer ring with raceways for two axial cages and an extended inner ring, where the axial cages are centered. SRB Bearings can provide high precision and stiffness within a small envelope dimension. SRB Bearings have been developed to be a radial/axial support for precision ball screws of machine tools but also useful in other fields as packaging and automation. In order to obtain the maximum stiffness, SRB Bearings are preloaded by means of a locknut.
