Our proprietary hydraulic system enables a single-bolt connection. By using friction rather than a keyway to join the shaft and hub, we have overcome the drawbacks of keyway connections. The design is simple, making installation and removal easy, while allowing for precise positioning and alignment. This significantly reduces the time required for assembly and adjustment. The body is made of stainless steel for enhanced corrosion resistance.

  • We only support shaft tolerances of h7 (g6·h6).
  • The allowable torque is the value when the thrust force is zero, and the allowable thrust force is the value when the torque is zero.
  • The allowable torque, allowable thrust load, axial side load, and hub side load are values at 20°C.

  • The ΦD2 dimension is the measurement taken before tightening the <ETP-E Plus>.
  • The designation for Pressure Screw M is based on the quantity and thread size.
