POLY STAR offers a wide variety of designs and sizes of pneumatic seals to suit different operating conditions.
A pneumatic seal prevents compressed air from leaking as the piston and rod of a pneumatic cylinder move back and forth. It works on the same self-energizing principle as a hydraulic seal, but is designed with low-friction materials and a thinner profile for a lower maximum pressure rating (typically up to 16 bar), favoring lightweight, high-speed operation.
Piston seals for pneumatic cylinders, optimized for low-friction, low-pressure environments.
Seals and protects the rod section of pneumatic cylinders from contaminants.
Low-friction, low-pressure (typically up to 16 bar) design suited to lightweight, high-speed motion.
Material choice — PU, NBR, or PTFE — matched to wear and friction requirements.
Piston and rod seals combine to form a complete pneumatic cylinder seal set.
Stable durability under the repeated cycling of automated equipment.
Detailed technical data and specifications are available on request.
