All bearings are over-dimensioned to maximise reliability. Antifriction coating eliminates stick-slip effect. Fast and accurate setting-up is ensured by the face-plate system with integrated four-way adjustment. Variable 30° and 72° indexing with +/- 1° fine adjustment is standard. Maintenance free hardened ballscrews and nuts ensure backlash free stroke setting in seconds - The Benefits of Precision. Setting-up System Integrated 4-way adjustment allows easy, accurate and fast operations. Variable 30° and 72° indexing. Dynamic balance ensured by reading the headstock manometer. Bearings The double tapered SKF bearings in the head- and tailstocks are greased and sealed for life, ensuring trouble free operation for life. Heavy-duty Set-up In-process measuring gauge, heavy-duty steady rest, extra counterweights and belt polisher. The complete heavy-duty set-up for the largest crankshafts.
