Pneumatic Piston Seal Type KDN | Low-Friction & Long-Life Sealing
Solution Designed for High-Speed Pneumatic Cylinders | Significantly Reduces
Breakaway Friction | Improves Cycling Efficiency and Reliability
Product Overview
The Type KDN Pneumatic Piston Seal is a high-performance sealing
component engineered with innovative low-friction materials and a unique lip design. Optimized to address challenges such as dry friction, high-speed
motion, and high cycling frequency in pneumatic systems, it
effectively reduces energy consumption, ensures smooth operation,
and significantly extends the service life of cylinders.

Key Features & Benefits
Ultra-Low Friction: Made from modified PTFE or specialized polyurethane materials, it
minimizes breakaway friction, ensuring smooth cylinder movement
even at low speeds without "stick-slip" phenomena.
Zero-Leakage Performance: The precision-designed sealing lip delivers excellent sealing
even at low air pressures, minimizing internal leakage and ensuring
consistent output force.
Extended Service Life: Exceptional wear resistance provides a lifespan several times
longer than traditional seals, drastically reducing maintenance
frequency and total cost of ownership (TCO).
Broad Temperature Compatibility: Maintains stable performance within a temperature range of -20°C to +110°C, suitable for most industrial environments.
Easy Installation: Symmetrical or asymmetrical design (depending on the specific
model) with simple groove design for straightforward installation,
reducing errors.
Industry Applications
This seal is ideal for:
Factory Automation: Robot drive cylinders, gripping units, linear drive modules.
Food & Beverage Industry: Equipment compliant with relevant regulations (specific material
certifications available upon request).
Semiconductor & Electronics Manufacturing: High-precision pneumatic equipment in cleanroom environments.
Medical Devices: Respirators, analyzers, and other applications requiring quiet
and smooth operation.
