Spacer device for a grinding roller

Abstract

A spacer device for a grinding roller, in particular of a grinding machine, including a main body to which at least two rolling bodies are rotatably mounted and wherein the spacer device can be supported by way of the at least two rolling bodies against a surface to be ground during a grinding process. At least one fixing device is arranged, preferably centrally, between the at least two rolling bodies and with which the grinding roller can be preferably releasably fixed to the spacer device. Furthermore, an adjusting device allows the grinding roller in a state of being fixed to the spacer device to be adjustable relative to the main body and/or at least one of the at least two rolling bodies.
