HYDRAULIC, SINGLE ACTION HOLLOW PISTON CYLINDERS – 705 SERIES
These hydraulic cylinders are single acting with spring retraction. A typical application for hydraulic hollow piston cylinders is when pulling and/or pushing forces are needed for clamping. The piston inserts, which can be mounted in the thread on the top end of the piston, are used to secure threaded bolts or screws. The piston inserts are available with the internal thread (type A) or with the through-hole (type B).
