PolySlide® Comparison
This new product, PolySlide® composite cylinder tubing, eliminates known problems with gel-coated composite cylinder tubing. Advantages over gel-coated cylinder tubing include:
- Inherently self-lubricating composite wear surface
- Lower coefficient of friction during cycling
- Longer seal life during operation
- Eliminates manufacturing concerns related to EPA regulations
- No delamination of gel-coated liner is possible
- Impact and fatigue resistance of liner is improved
- Higher degree of embeddability of wear surface
The uniqueness of the PolySlide® bore surface provides advantages over the gelcoated cylinders. These advantages include the elimination of delamination concerns of the gelcoat with the backing material. The adhesion friction is normally greater with gelcoated surfaces. The following case study compares the performance of PolySlide® and a gelcoated composite cylinder.
Case Study: Endurance Test of Legacy-Era Gel-Coated Vs. PolySlide®
In this study, three 4"x10" stroke cylinders of a gelcoat and PolySlide® cylinder were mounted vertically with a 10 lb. weight attached to the rod end. The test pressure was set at 42 psig and the cylinders were allowed to cycle freely through a 7" stroke for 5,000,000 cycles. The cycle rate was primarily governed by the seal resistance due to friction between seals and bore surfaces. The chart above shows how the average cycle rates changed throughout the tests between the two types of cylinders.
