Structural Test Actuators

Swivel mounted actuators suitable for structural testing: BiSS double ended - double acting contamination-insensitive servo hydraulic actuators are designed for static and dynamic testing. They generate equal axial forces in tension and compression with excellent dynamic characteristics. Controlled displacements, loads and velocities are achieved with the use of appropriate servo valves, digital servo control, gauges, transducers and a high pressure hydraulic supply system. BiSS servo-actuator rod assembly is provided with internal threading to accommodate industry standard metric threaded adapters. The servo-actuator assembly is front-flange mounted directly onto load frame platen

Note: Assembly dimensions are subjected to minor variations depending on specific ratings.
        • Metric threading
      • Length (L) for total stroke of 50 mm
      • Length (L) – with retracted piston position
      • Length (L) = A + B + S + C + D + E + F
      • D = 50 mm
      • C = B – 40 mm
      • A = 220 mm
      • C = B–60 mm for 500 &100 kN
      • D = 200 mm for 500 &1000 kN
      • Custom manifolds available
