Composite tubing replaces metallic material

by Today's Trucking

Polygon Composites Technology’s PolySlide Composite Tubing for pneumatic and hydraulic cylinders will replace metallic material in a variety of applications.

PolySlide – made from continuous filament-wound glass fiber and polymer resins — comes as a cylinder tube ready for assembly, or as fully engineered assemblies that would be used by equipment manufacturers.

The fiberglass filament and resin form a high-strength component that exhibits dimensional stability, is non-corroding, resists impingement, and is non-conductive, the company says. The cylinder tubing holds up in the face of extrene temperatures, grease, grit, salt, and chemicals.

Tubing sizes range from a 0.25-inch inner diameter up to an industrial-sized 24 inches. And the seal is able to slide over the bore surface contour, minimizing friction. The inside diameter also has a smooth finish.

Contact with the non-metallic rod guide bearing prevents galling and provides for a low coefficient of friction, Polygon adds. A wear resistant material incorporated into the bore surface further increases the lifespan of the composite cylinder tubing.

It’s used in pneumatic and low-pressure hydraulic applications like fifth-wheel actuators, gate valve actuators, tie rod cylinders, and more.
