Abstract:  
An assembly for improving the qualites, such as hardening, smoothness, etc. of cylindrical surfaces. The assembly includes a plurality of roller bodies circumferentially and uniformly distributed about a predetermined axis. A cage means supports the rotary bodies for free rotary movement. An elongated tapered cam means whose axis coincides with the predetermined has a plurality of pressure surfaces engaging the roller bodies for urging them against the surface which is to be rolled, while between these pressure surfaces the cam means has a plurality of relief surfaces alternating with the pressure surfaces and providing relief of the pressure between the roller bodies and cylindrical surface. A drive means is operatively connected with the cam means for rotating the latter as well as for axially feeding the cam yielding in opposition to the feed of the cam means when the pressure surfaces engage the roller bodies, while when the relief surfaces are respectively in alignment with the roller bodies the spring means brings about feeding of the cage means together with the roller bodies.
