What you need to know about Piston Seals

Dec 20, 2018 2:16:59 PM LEAVE A COMMENT

Piston sealing is critical to proper cylinder function.  Piston seals keep fluid from bypassing the piston which would otherwise reduce the pressure differential across the piston and in turn reduce the available force for the cylinder to perform work.

Single or Double Rod End Cylinder

Dec 4, 2018 1:13:34 PM LEAVE A COMMENT

One of the very basic elements in designing a cylinder to meet the needs of a machine is the determination of whether or not the cylinder should be a single or double rod cylinder.  Each type has its own distinct advantages and disadvantages, and is an important early step in the cylinder design.

Cylinder Bore Sizing

Oct 30, 2018 2:17:22 PM LEAVE A COMMENT


A critical decision to make when designing a cylinder is the size of the bore. The bore is the inner diameter of the cylinder tube, which can also be known as the barrel. The bore size, along with the known operating pressure of the cylinder determines the force output of the cylinder. Many hydraulic systems are designed to run at 3000 psi hydraulic pressure, while most pneumatic systems are designed to run at roughly 100 psi.

How Hot is too Hot for your Cylinder Application??

Jul 31, 2018 10:15:00 AM LEAVE A COMMENT

There are many applications where cylinders are exposed to extreme heat due to environmental conditions. Whether your cylinder is near a bakery oven or hanging above a crucible of molten metal knowing which options are available to handle the heat becomes top priority.

Pneumatics: Ideal for the Sawmill Industry

Mar 19, 2018 8:35:13 AM LEAVE A COMMENT

   Keeping up with production demands is a proven challenge in the lumber industry. To stay competitive, operations demand higher performance and lower cost for automated equipment. Lumber processing end-users want solutions to the problems encountered in the rough environment of the mills where temperatures fluctuate, dust produced from the processes damages your equipment, and grate machinery.

How to Calculate Hydraulic and Pneumatic Cylinder Buckling

May 18, 2016 7:00:00 AM LEAVE A COMMENT

Much the same way that you want the columns on your front porch to have the strength to support the roof --avoiding any and all Tim the Tool Man Taylor incidents -- column strength is a critical piece when addressing cylinder design as well.  So many of us don’t understand what it is and how important it is; let's investigate some of the factors associated with it to help gain a better understanding.

Enhancing N.F.P.A. Fixed Non-Centerline Cylinder Mounts

Jan 27, 2016 8:00:00 AM LEAVE A COMMENT

                  As mentioned in an earlier article, one of the three N.F.P.A. cylinder mounting classes is fixed non-centerline mounts. These mounts include side lug (MS2), end lug (MS7), side flush (MS4), and foot bracket (MS1). In applications where a fixed non-centerline mount is required, Sheffer strongly recommends employing a thrust key plate or dowel pinning the cylinder depending upon the specific mount. This is done to minimize shear loads on the mounting bolts as well as providing a means of cylinder alignment.

Seek Help Choosing Fluid Power Cylinder Seals and Materials

Nov 24, 2015 7:00:00 AM LEAVE A COMMENT

In 1962, E.F. Houghton Co. published A Handbook On Hydraulic and Pneumatic Packings for the fluid power industry. In the opening chapter there is an illustration of a “typical animal hide” which depicted the best parts of the hide that could be fabricated into leather “U” cups, “V” rings, and gaskets to seal fluid power cylinders.
