Servo-hydraulic testing actuators

Zwick's servohydraulic testing actuators feature sturdy, durable construction and are used both inservo-hydraulic testing machines and as single actuators, for example on a clamping plate. When used in conjunction with a servo valve they enable complex loading sequences to be implemented with great accuracy.

  • Available in various versions with test loads from 5 to 2500 kN.
  • Standard testing actuator stroke is 50, 100, 150, 250 or 400 mm.
  • Designed for systemn pressure of 210 or 280 bar.
  • Double-rod cylinder with equal piston surface area for tension and compression.
  • Hydrostatic piston-rod bearings guarantee quasi-frictionless operation and high transverse force absorption.
  • Hydraulic end-cushioning allows high piston speeds.
  • Fitted with integrated displacement transducer.
  • Top or bottom-mounting
