Power Supplies
Screw Pumps, Threaded Body or Block Body
Simple, inexpensive power supply for small systems. Ideally suited to powering work supports when used on manual clamping fixtures. Heavy duty threaded screw can be driven by a precision “nut runner” for fast and precise actuation (maximum RPM = 500). Block style bolts down, threaded body can be mounted through a bulkhead with the two retaining collars provided. Use of impact drivers on device voids warranty.
