19.2 ydraulic Systems Series 1 ydraulic Threaded ody ylinders Product Overview The single-action, spring-return hydraulic power cylinders are small pistons that can be used singly or combined. They offer tremendous force in a small, easily mounted package that can be used in any attitude and requires only a single inlet port. They are often used grouped together by a common manifold to provide as much force as needed for the operation. For a relatively small volume of oil, they provide exceptional exerting force, and are generally the best choice if stroke lengths can be kept short. Threaded body for easy mounting Small size permits low profile workholding ccessories available for easy mounting vailable in metric or inch sizes (Metric on special request) ardened piston and rod Single-acting for simple plumbing Wide variety of sizes and strokes Pressure capacity up to 5, PSI, provided piston does not bottom out Technical Information Model no.
