Threaded-Body Hydraulic Cylinders
Small yet powerful, these cylinders thread into a system for workholding applications. Hydraulic pressure extends the piston rod and an internal spring retracts it. UN/UNF (SAE Straight) thread connections have straight threads and are also known as O-ring Boss fittings.
When using a mounting block, a mounting nut is required.

Round Body Hydraulic Cylinders
More compact than hydraulic cylinders with external tie rods, these cylinders have a round body that fits better into tight spaces and have a more streamlined appearance. To further minimize their footprint, they operate without an air cushion. These cylinders are double acting, meaning they both push and pull loads. They use two hydraulic ports, one to extend the piston and one to retract it. Because the piston is magnetic, these can be used with sensors to indicate piston position.
