Supplying you with quality, reliable single acting hydraulic cylinders…
“I’d like to say that your service was first class from enquiry to dispatch and we would have no problem in using Hydraulics Online in the future.”
Searching for a quality, efficient single acting cylinder? Look no further. With over 60 years’ combined experience in hydraulic system design and component supply, specifying the right single acting cylinder is like falling off a log to the team here at Hydraulics Online. And with the backing of our ISO 9001 Quality Management accreditation, you can rest assured that your brand is in safe hands… we can give you as much or as little guidance and advice as you need to help you choose the best single acting cylinder for your application.
Single acting cylinders are the most popular type of hydraulic cylinder. They are simple and cost-effective and also easy to use and install; making them useful when the application involves lifting and the weight on the cylinder is sufficient to bring the cylinder back down.
They have one operative area, situated on the bottom side, which applies force in one direction only. In most hydraulic systems, these are designed as plunger cylinders (that can only be used as a pushing cylinder) and an external force is applied to return the piston to its starting position: e.g. lifting devices, upstroke presses, etc. If there’s no power to return the piston to its starting position, it is necessary for springs to be applied. This can only happen with small cylinders due to the restricted force and stroke length of the return springs. Assembly tools and installation work are both examples of applications that would use a spring return single acting cylinder.
So how does a single acting cylinder work? With a single acting cylinder when fluid flow is applied to a port in the closed end, the shaft extends until the collar or piston reaches the shaft end. When an external weight or load is placed on the shaft, the shaft will withdraw into the chamber until the piston or collar reaches the closed end. The cylinder will create an output force at the shaft end in proportion to its internal closed end area multiplied times the pressure potential of the fluid power system.
Our catalogue shows our standard range of single acting cylinders offering: a 25mm – 100mm bore range, a rod length ranging between 16mm – 50mm, stroke sizes ranging from 50mm – 1000mm and a 200 bar rated maximum working pressure.
But if you are looking for a particular model or brand of single acting cylinder we can help there too. Our extensive, competitive access to both leading and lesser known hydraulic equipment manufacturers means that many of our customers choose to us us as their single source of supply.
To bring some of this to life a little, and to give an example a single acting cylinder we’ve provided, a leading manufacturer of concrete products tasked Hydraulics Online with designing a complete hydraulic system that would meet the customer’s exact requirements.
A full system was designed and provided including single-acting, telescopic lift cylinders and complete power pack. It was successfully fitted and commissioned and is now used in their daily manufacturing process.
But don’t just take our word for it. If you want to see more of what our customers say about us, take a look at our testimonials and case studies. If you need any more information on single acting cylinders (or any other type of hydraulic equipment come to that) then take the “plunge” and get in touch with our fabulous technical team.
