Hydraulic Nut PG 10
The distinguishing feature of the Hydraulic Nuts of product group 10 is that the axial pretensioning force is produced by a ring piston and maintained by a mechanical lock ring and that the hydraulic pressure may be released.

Main Features


  • single-stage
  • also used to generate axial displacement forces
  • mechanical locking
  • annular piston

Advantages of PG
  • integrated mechanical locking
  • pre-tensioning force is maintained without pressure
  • otherwise, like PG 9

Examples of Applications
  • rolling mill construction
  • shears, cutters
  • heavy engineering
  • general engineering
