According to Olsen Engineering,
roller screw actuators are winning
market share from ball screw,
pneumatic and hydraulic actuators
because they offer benefits in terms
of life, accuracy, robustness, load
capacity and compactness.

Olsen Engineering’s roller screw
servo linear actuators are said to take
up much less space for a given load
rating and provide up to 15 x travel
life. The new Tritex II series of servo
linear actuators incorporates a
brushless servo motor, servo
amplifier and position controller in a
single industrial grade enclosure.
Simply connect 1 phase 240V and
give a control signal.

Products range in frame sizes from
40 to 215mm, with force ratings up
to 288kN and linear velocities up to
1.5m/sec, stroke lengths up to 8m
and 3µm accuracy. Zero backlash
options and ATEX versions are also
available. Stand D3402
