Biomch-l listers,

I am presently using a Hurst SLS linear actuator (stepping, not synchronous)
which moves a rod bi-directionally through the centre of itself. I would
like to know of a manufacturer who makes a more powerful motor of this
design (max thrust of Hurst rated at 25 lbs.). The speed of advancement
must be about 5 mm/sec. I will post a list of responses.
