The shaft and hub are connected simply by tightening a few clamping bolts on the flange surface. Our proprietary hydraulic system uses friction to secure the connection, thereby overcoming the drawbacks of keyed connections. The design is simple, making installation and removal easy, while enabling precise positioning and indexing. This significantly reduces the time required for assembly and adjustment. The system uses hex bolts.
