About This Product

CST9191 is a single-acting, spring return workholding cylinder from the Enerpac CST series, featuring a 1.000-12 UNF externally threaded body. The threaded body allows it to be screwed directly into a fixture or clamping device for fine positioning. At a maximum operating pressure of 345 bar (5,000 psi) it delivers 8.7 kN (1950 lbf) of push force. Stroke is 19.3 mm (0.76 in), effective area 2.52 cm², advance oil capacity 4.8 cm³, overall length 98.3 mm and weight approx. 0.36 kg. The body is steel with a solid plunger. It is used as a push cylinder in workholding applications such as CNC machining fixtures, welding and assembly jigs where high clamping force is required in limited space.
