** Cylinder capacities are listed at 5,000 psi maximum operating pressure. The output force is adjustable by varying hydraulic pressure. To determine approximate output force, use the following formula: Effective Piston Area X Input Pressure = Clamping Force (Actual force may vary slightly due to friction and/or return springs.)

Features

Block Pull Cylinders

Single Acting

No mounting hardware required, just bolt in place to secure these "draw" action cylinders
Adjustable force ranging from "negligible" to maximum cylinder capacity, just adjust the input pressure
Normally extended piston provides a simple device for actuating clamping mechanisms, device manipulation or disappearing spring crowders

Threaded plunger ends allow the attachment of custom end treatments or the use of bolts to pull "C" washers.

Hardened chrome alloy steel pistons won’t "mushroom" or wear unevenly.

Vent port with bronze filter gives the cylinder a place to "breathe" and helps keep chips from drawing past wipers.

Specially designed springs run longer, require less maintenance.
