About This Product

Enerpac CST471 is a single-acting, spring-return, threaded-body hydraulic workholding cylinder from the CST series. Its .750-16 UNF threaded body screws directly into the fixture, allowing fine positioning and easy installation. The cylinder delivers 4.4 kN (980 lbs) push capacity at a maximum operating pressure of 345 bar (5,000 psi). Stroke is 6.9 mm (0.27 in), effective area 1.29 cm² (0.2 in²), advance oil capacity approx. 0.82 cm³ (0.05 in³) and weight approx. 0.18 kg (0.4 lbs). The solid steel plunger is center-tapped with a #8-32 UNC thread. Its compact design suits space-constrained machining fixtures, CNC workholding and high-cycle clamping applications in series production.
