Tips: Tips for Choosing Cylinder Size

The diameter of the cylinder piston rod is very important. A more common mistake in cylinder design can be an undersized piston rod, making the cylinder more susceptible to stress, wear and failure. Piston rod diameters can range from 0.5 inches to over 20 inches, but they must be sized for the available load. In pushing applications, it is important to correctly size the rod diameter according to Euler calculations to avoid rod buckling or bending. When designing a cylinder to generate the required force, the size of the cylinder rod is always the primary consideration.

Prevent the rod from bending. In a long-stroke cylinder, a fully extended rod can bend under its own weight. Excessive bending can cause wear and damage to seals and bearings. It can even cause the piston to cock up in the hole, scratching and damaging the inner surface of the cylinder. Rod deflection must not exceed 1 to 2 mm.

When choosing the right size, we also need to pay attention to the impact load of the cylinder. Stroke length, the distance required to push or pull a load, can range from less than an inch to several feet or more. But when the cylinder is extended or retracted, make sure the piston doesn't bottom out and create a shock load at the end of the stroke. Engineers have several options: add an internal cushion to slow the load near the end of the stroke; add an external mechanical stop to prevent the cylinder from bottoming out; or use proportional valve technology to precisely meter flow and safely slow the load.
