Excellent in actuation systems and valves

Polygon produces several products for the fluid power industry.

Guide Rod Bearings

PolyLube® Guide Rod Bearings are designed as replacements for traditional metallic guide rod bearing materials. Replacing conventional metallic guide rod bearings with a PolyLube guide rod bearing is a straight-forward change out.

PolySlide® Composite Cylinders

For decades Polygon has satisfied customers in the fluid power industry. With strengths well beyond conventional materials such as thermoplastics and acrylics, maximum resistance to corrosion and weight reduction (especially in comparison to metals) and resistance to denting; Polygon composite cylinders have a proven record.

Case Study – Valves

Rusty valve 99273141Municipal water valves often have infrequent actuation. They may have only one actuation per year or longer, and are prone to rust seizing. Unexpected maintenance delays can be costly in such a time-sensitive application.

Solution – Composite Bushings and Cylinders

Polygon's composite cylinders often serve alongside our PolyLube bushings. They are also non-metallic, and feature a smooth bore surface for a positive seal with metallic valve components. The durable yet low friction bore not only prevents rust seizing, it also reduces required force, a benefit for remote valve actuation solutions. Composite cylinder actuation and valve stem bushings are a real "rust busting" duo.
