SERVO-HYDRAULIC ACTUATORS

BISS double ended - double acting servo hydraulic actuators are designed for static and dynamic testing with robust side load tolerances to provide unmatched strength and durability. These heavy duty force generators apply equal axial forces in tension and compression with excellent dynamic characteristics. The design incorporates low friction, wear resistant seals for smooth and leak free operations. BISS actuators incorporate a monolithic piston design with inbuilt digital encoder of 0.1 µ resolution to track displacements, these features make our actuators more reliable with precise control to meet most of the demanding applications of testing.

Available in wide range of force capacities and stroke, these actuators are easily interfaced with various transducers, swivels, swivel bases, pedestal mounts, servovalves, manifolds and hydraulic power sources to ensure consistence test results.

Features

  • Superior and reliable force ratings staring from +/-5 to 3000kN with stroke lengths from +/-25 to +/-500 mm
  • Hydrostatic actuator configuration available up to 500 kN capacity
  • Double ended double acting monolithic piston design to apply equal axial forces in tension and compression
  • Linearity: 0.10% to 0.25% of full scale measuring range
  • Heat treated and hard chrome plated precisely machined piston rods for smooth operations
  • Metric threading on rod end to interface with various adapters and force transducers
  • Coaxially mounted encoders with 0.1 micron resolution for precise control of displacements
  • Non-metallic, low friction and wear resistant seals improves life and side load bearing capabilities
  • Hydraulic cushions at either ends provide accidental damages to end caps
  • Servo valve manifolds with oversize ports and provisions for interfac­ing to a variety of servo valves and service manifolds

Applications
