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.

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.

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.

Let's take it back to the Basics! Like... what is a Cylinder??? What do all these words mean?! How do I know what to order?? Let me help you with some specifics to cylinders and to our Sheffer line!

We all know the name Steve Jobs very well. Jobs was fired from his own company in 1985. Jobs easily could have felt sorry for himself, felt defeated, and played victim after being fired. He chose otherwise. After he was fired, he saw the problem or crisis and took authority over the situation, seeing opportunity where others doubted. He went on to start a small animation company and turned it into the giant that is now Pixar. Once The Walt Disney Company bought Pixar out in 2006, Steve Jobs became the largest shareholder in Disney. Point being unwanted change happens; look beyond it and embrace the discomfort it brings. Every Problem presents an Opportunity.
