Abstract

A roller casing for a pulley is comprised of coaxial ring halves mounted one over the other. The diameter of the running surface can be varied without varying the bearing size by employing corrugations in the circumferential direction, or by providing lateral radially outwardly directed rims on the inner ring part. Alternatively the iner ring may be comprised of two ring halves having their central parts directed toward one another.
