Composite Pneumatic & Hydraulic Cylinders & Tubing Material Composition

The PolySlide® and PolySight® products are supplied as a cylinder tube ready for assembly, or as a complete cylinder designed for your application. The cylinder tubing is available in standard sizes or can be designed to your requirements.PolySlide® FeaturesThe bore surface of the PolySlide® cylinder improves seal wear by reducing friction. There are two types of friction that oppose each other in the bore surface: adhesion and interlocking friction. Adhesion Friction is the physical attraction of two smooth surfaces brought into close contact with each other. As the contact area increases, so does the adhesion between the surfaces. A smooth surface reduces the gap between the surfaces resulting in higher adhesion. Adhesion acts as a frictional force when the one object slides against the other. The friction between O-ring seals and bore surfaces increases significantly as the surface finish of the bore is reduced from 16 Ra to 6 Ra. A higher Ra bore surface finish will reduce the seal adhesion friction and extend seal life. Interlocking Friction is the result of shear forces encountered from irregularities between contacting surfaces during sliding motion. Machined surfaces created by boring or honing produce microscopic rough edges that penetrate and shear the softer seal material and reduce seal life..
