The built-in piston consists of a piston and a threaded bushing and it includes all seals.

The built-in piston is a subassembly, which has to be integrated directly into the housing body. The housing body has the features of the cylinder housing. The advantage of this design is the minimized space requirement of the clamping or operating cylinders.

The threaded bushing is equipped as standard with a metal wiper as well as a soft wiper. The hydraulic oil is fed through drilled channels.


Special features:
  • space-saving installation options

  • installation directly into the housing body

  • with soft wiper and metal wiper as standard

  • oil supply through drilled channels

  • standard pistons and special designs available

Operating conditions:

The built-in piston operates hydraulically double-acting. This enables retraction forces as well as extraction forces to be generated. Use appropiate seals according to the temperature conditions. The dimensions for manufacturing and the tolerances for surface and dimensions must be complied according to the HYDROKOMP drawings.

After tightening the threaded bushing, it is necessary to secure it by using the supplied threaded pin. For this, a small thread must be fitted into the threaded bore of the bushing into which the threaded pin is screwed.
