Product Description
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.
  • Packaging & Handling Equipment: Sorting machines, labeling machines, filling machine cylinders.
  • 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.
