Abstract
Abstract An arrangement for adjustment of a rolling bearing which is radially and axially movable inside a sleeve. A helical spring is arranged with prestress between the base of the sleeve and a side surface of the outer ring of the rolling bearing. The terminal windings of the spring are radially restrained by form-locking with projections on the base and the side surface.

Claim 1
Independent Claim
133 words
An arrangement for adjustment of a rolling bearing having an outer ring with a side surface, said arrangement including a sleeve in which said outer ring is radially and axially movably arranged, said sleeve having a base connected thereto, a helical spring arranged with prestress between said base and said side surface of said outer ring, wherein first projection means connected to said base and second projection means connected to said outer ring, whereby said first and second projection means are radially displaceable relative to each other, said helical spring being arranged to radially form-lock with said first and second projections means by means of terminal windings at respective ends of said helical spring, wherein said first projection means comprises a plurality of circumferentially distributed, axially extending, radially stamped depressions in said sleeve.
Claim 2
Dependent Claim
