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, allowing for easy installation and removal, as well as precise positioning and indexing. This significantly reduces the time required for assembly and adjustment. The product features an electroless nickel plating finish.

  • Dimensions L1 and L2 apply when the <ETP-CLASSIC> is installed. These dimensions may vary slightly depending on the fit tolerances of the shaft diameter and hub bore.
  • The price of Clamping Bolt M is calculated as: quantity × thread size × nominal length.
