What is a Pneumatic Seal?

A Pneumatic Seal is a precision sealing ring engineered specifically for compressed air actuators and pneumatic cylinders. It prevents compressed air leakage between piston chambers or along the rod, maintaining fast-cycling pneumatic force and stroke repeatability.

Engineered from abrasion-resistant polyurethane (PU) and specialized low-friction NBR compounds, pneumatic seals excel in high-speed, low-lubrication operating environments common in automated packaging, assembly lines, and bottling plants.

Frequently Asked Questions (FAQ) - Pneumatic Seals

What is a Pneumatic Seal and where is it used?
A pneumatic seal is engineered specifically for compressed air actuators, automation cylinders, and pneumatic valves. It prevents air leakage under reciprocating motions, featuring high velocity tolerance and self-lubricating lip profiles.
How do pneumatic seals differ from hydraulic seals?
Pneumatic seals operate under lower pressures (typically up to 10-16 bar) compared to hydraulics (up to 400 bar), but at significantly higher linear speeds and under minimal fluid lubrication conditions.
What is the function of a Cushion Seal in pneumatic cylinders?
Cushion seals decelerate the piston smoothly at the extreme end of stroke, preventing metal-to-metal impact, reducing operational noise, and extending cylinder lifespan.
