The 500mm to 2000mm clamping capacity ranges on heavy duty lathe chucks implies it has oversized jaws which enable powerful clamping of gear driven jaw mechanisms. The jaws alone can provide a high radius of 200kN clamping force. The entire structure is made out of heavy duty materials and is intended for severe working conditions. The dual row angular contact bearings amde out of cast iron are meant to endure loded thrust and rotation and the whole lathe chuch is built as a gentle power tool for sensitive operation. These are used in energy and ship building industries for rotor shafts and pipe flanges machining as per API 6A standards oilfield equipment.
