Combined axial/radial bearing UNITEC

SRB - Needle and roller bearings for screw drives


SRB series bearings consist of a needle roller radial bearing with solid outer ring and an extended inner ring. The side surfaces of the outer ring act as tracks for the two axial cages.The two axial cages are centered on the inner ring.
Thanks to this design it is possible to realize a precision journal, having little overall dimen sions and high stiffness.

All SRB bearing designs have been developed in order to be a radial/axial support for precision ball screws of machine tools. In order to obtain max stiffness, these bearings are preloaded by means of a locknut.
