ETP Bushes

ETP Bushes consists of a thin walled cylinder filled by a 'medium'. When this medium is pressurised, they tend to expand the thin walled cylinders and grip both the shaft and the component at the same time.

To mount any product onto a shaft – Position the ETP Bush on the shaft/product, & just tighten the screw. This tightening increases the pressure on the medium which expands the inner/outer walls of the Bush to grip the shaft and the component

ETP-Classic is available as standard for shafts, also imperial and a short version, (type S). Also available in stainless steel ( type R). The small number of clamping screws with low tightening torque, makes the mounting/ dismantling procedure fast and easy


  • ETP-Classic is a hydraulic connection which consists of a double-walled hardened steel sleeve, filled with a specially developed pressure medium, sealing ring, piston, pressure flange and cap head clamping screws. ETP-Classic type R is made of stainless steel and has hex head stainless steel clamping screws. This in order to facilitate easy cleaning, essential within food processing.

  • 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. ETP-Classic type R has a few more clamping screws, as the tightening torque is lower for stainless steel screws.


  • Easy and accurate positioning
  • Short lengths and outside diameters - making them compact
  • Quick mounting
  • Good run out (both axial and radial)
  • Speedy assembly/Dismantling
  • Mounting and dismantling is fast
  • Service and maintenance are also quick

Benefits and Features:
  • Small built-in dimensions
  • Mounting and dismantling is fast
  • Fine adjustment of the hub can be made during mounting
  • Low tightening torque and a small number of screws makes the mounting easy
  • Good concentricity, also after several mountings
  • Hex head screws available as accessories.

We are offering ETP Keyless Bushings to our clients.

  • These products replace keys and keyways, for connection of a shaft to a hub. Keyway transmission increases the cost due to various operations involved including downtime, machining time, lateral shifting of key-ways in the process, etc.
  • There are ETP keyless locking device models designed to solve specific requirements such as high transmittable torque and special applications.
  • They are the best solution where keyways and tapers can weaken due to excessive usage or when high torque and a good runout are required.
  • ETP Classic and Express models are also available in stainless steel for corrosion protection.
