Polygon 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.
