The MTS cylinder provides superior non-rotating accuracy and linear
stability in a compact package. Traditional non-rotating cylinders
typically can only hold position to within 0.5° and have inherent
sealing problems. Integrating a ball spline as the rod bearing, this
cylinder approximates the non-rotational accuracy of a guided cylinder
without the added space requirements of external guide rods. In
addition, a special rod seal design limits leakage to the equivalent of
a round piston rod seal. An optional end lock retains the rod in the
retracted position even in the event of loss of air pressure for added
safety. Mounting can be done from four precisely machined faces with
parallelism of less than 0.1mm.
