Abstract
More specifically during manufacture of hydraulic cylinders for the crane industry, tubular bodies must be rolled on their inner and/or outer surfaces, in order to be able to ensure a sufficient durability of the hydraulic cylinders. Tools with a rolling body guide are used for this. The disadvantage of the prior art is that the replacement of a rolling body guide leads to immobilization times. The present invention therefore proposes an improvement to the prior art with a rolling body guide for receiving and feeding rolling bodies which are used for finish rolling or roller compression of an inner or outer surface of a tubular body and where the rolling body guide has at least two defined detachable receiving sections, so that a modular assembly of the rolling body guide is realizable.
