Composite tubing for pneumatic and hydraulic cylinders

Polygon Composites Technology (Walkerton, Ind., U.S.), manufacturer of composite tubing solutions for bearings, dielectric
applications, surgical devices and more, has launched PolySlide
composite tubing for pneumatic and hydraulic cylinders.
PolySlide tubing can reportedly replace metallic material in a
variety of cylinder applications.
Supplied as a cylinder tube 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 and is non-corroding, impingement-resistant and non-conductive. The tubing is said to perform
in high and low temperatures, and withstands grease, grit, salt,
chemicals and other extreme conditions.
PolySlide tubing sizes range from as small as 0.25-inch inner
diameter (ID) up to industrial-sized 24-inch 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 increases the lifespan of the composite cylinder tubing.
According to Polygon, common applications of this product
include use with 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 tubing is also available.
