We manufacture chain rings especially for rotary chains according to DIN 8182 / DIN 8188 / ANSI 29.10 / RO3140 / RO3160, which can be screwed or welded directly on a drum. The chain rings are CNC milled and powder or inductive hardened on request. All chain rings are pre-fitted according to a special procedure so that they fit 100% on installation. It goes without saying that we also supply the matching, ready-to-mount pinion. We generally manufacture rotary sprocket wheels to all graduations.
