Enerpac Workholding Cylinder Accessories

Enerpac Workholding Cylinder Accessories
Workholding cylinder accessories are provided so that you can effectively position, mount and actuate Enerpac hydraulic cylinders according to your specific fixturing or production applications.


Enerpac Collet-Lok
Enerpac Collet-Lok products combine the automation of hydraulic actuation with the security of an internal locking mechanism. After actuation and locking, these products maintain their clamping or supporting capacity without maintaining hydraulic pressure in the circuit. Available in Swing, Push and Work Supports models, Enerpac Collet-Lok products are also available in numerous special configurations and modifications.

Pumps and Power Sources

Palletized Fixture Components

Enerpac Palletized Fixture Components
Enerpac provides a variety of solutions for use in palletized fixtures:

  • Manual and Automated Coupler Systems for connecting/disconnecting to the fixture
  • Rotary couplers for use with continuous connection systems
  • Pressure intensifiers to provide increased pressure for clamping when used with machine hydraulics
  • Safe Link for remote wireless monitoring of fixture pressure or clamp position

Safe Link Pressure and Position Monitoring

Enerpac Safe Link Pressure and Position Monitoring
SafeLink provides wireless communication between the fixture mounted SEND unit and the machine control interfaced RECEIVE unit. A pressure switch is used on the fixture to monitor the circuit pressure. If the pressure switch on the fixture goes open, the RECIEVE unit communicates the changed status to the machine control through either 24 VDC, Modbus RTU RS485 or Ethernet IP protocol or Modbus TCP/IP. The machine control would interrupt the machining process. The SEND unit can also be used with limit switch based position sensing clamps to verify clamped or unclamped status for robotically loaded systems.
