Designing with PolySlide®
PolySlide® product can be supplied in various forms ranging from a cylinder tube ready for assembly to a completed cylinder designed for a specific application. It is available in standard sizes or can be custom designed to customer's requirements.

* These values are intended as an initial design guide. It is the customer's responsibility to test and approve the actual values.
* For sizes other than listed or for assistance, contact Polygon's Sales Engineers.
* Good assembly practices to be employed in applying torque to the tie rods so as not to unequally stress cylinder.

Polygon's internal design capability goes beyond evaluation of the cylinder tubing material itself. Within our business portfolio is included a number of complete cylinder designs ranging from critical care respirator systems for paraplegics to rigid cylinders designed to be consistently exposed to road salt and wide temperature ranges.
The ability to design with PolySlide® has also allowed various food processing companies to explore composite tubing into caustic environments where sodium hypochlorite washdowns made any metal cylinder, even stainless steel, an unreliable solution.
End Cap Designs
End caps can be designed in various ways to meet specified requirements. The simplest means of attaching the ends to the cylinder is by the use of tie rods; however, Polygon has experience with other end cap attachment techniques.
For common cylinder sizes using tie rods see the table above for design details. Pre-load torque values are given here.
PolySlide® cylinders offer smoother walls, excellent impingement resistance, a wide temperature range, are resistant to corrosion and are lighter weight than their metal counterparts. The perfect combination for your next cylinder design project.
PolySlide® Lubrication Guidelines
For normal application the same lubrication and methods of application used for metallic cylinders can be used with PolySlide® cylinders. Normal pre-lubrication procedures are also recommended. In line or in service lubrication is acceptable but often not required.
For assistance in new application or questions relating to lubrication related to PolySlide® cylinders contact a Polygon Sales Engineer.
