Polygon announces composite tubing for pneumatic, hydraulic cylinders

Polygon Composites Technology Has Launched Poly Slide Composite Tubing For Pneumatic And Hydraulic CylindersPolygon Composites Technology has launched PolySlide composite tubing for pneumatic and hydraulic cylinders. PolySlide tubing replaces metallic material in a variety of cylinder applications, the company says.

Supplied as a cylinder tube ready for customer assembly or as fully engineered cylinder assemblies for equipment manufacturer applications, the tubing is made of continuous filament-wound glass fiber and polymer resins. The fiberglass filament and resin materials combine together to form a high strength component that exhibits dimensional stability, is non-corroding, impingement resistant and is non-conductive, the company says.

Polygon says PolySlide is the solution for service in harsh environments — the cylinder tubing performs in high and low temperatures, grease, grit, salt, chemicals and other extreme conditions.

PolySlide cylinder tubing sizes range from as low as 0.25-in. inner diameter (ID) up to industrial-sized 24-in. IDs. The features of the tubing allow the seal to slide over the bore surface contour, minimizing interlocking friction. The inside diameter of the tubing has a smooth finish. Contact with the non-metallic rod guide bearing prevents galling and provides for a low coefficient of friction. A wear resistant material incorporated into the bore surface further increases the lifespan of the composite cylinder tubing, the company says.

Commonly found in pneumatic and low-pressure hydraulic applications, such as fifth-wheel actuation, gate valve actuators, water treatment flow control mechanisms, tie rod cylinders and more, a translucent version of the composite cylinder tubing also is available.
