ETP Classic Design

ETP-CLASSIC consists of a double-walled hardened steel sleeve filled with a specially designed pressure medium, sealing ring, piston, pressure flange and clamping screws.

Operation of ETP Classic Keyless Shaft Bushings

When tightening the screws, the sleeve expands uniformly against hub and shaft and creates a rigid joint. When loosening the screws the sleeve returns to its original measurements and can easily be dismantled.

  • Highest radial load
  • Mounting and dismantling is fast.
  • Precision adjustment of the hub can be made during mounting.
  • Low tightening torque and small number of screws makes mounting easy.
  • Good concentricity even after many mountings.
  • Hexhead screws can also be used.
