  Clamping Bushes E-N

  MAEDLER

  Material: Stainless steel 1.405 (AISI 431).
  The clamping bush consists of a double-walled steel sleeve filled with a pressure medium, and a flange part. Inside the flange there is a screw and a piston with seal to build up compression.
  Function: When the thrust screw is tightened, the sleeve expands uniformly against shaft and hub, creating a rigid connection through frictional force. When the thrust screw is loosened, the bush returns to its initial position and can be easily disassembled.
  Concentricity: 0.02 mm.
  Tolerances: Shaft h7 for d = 15 mm.
  Shaft k6-h7 for d = 19, 22, 24, 28 and 38 mm.
  Shaft h8 for the other diameters d.
  Hub H7.
  Temperature range: -30 oC to 85 oC.
