Solve Miniaturization Challenges: Achieve smooth, quiet, and reliable cushioning in miniature and dual-axis cylinders where traditional stepped buffers cannot fit.
Product Overview: Precision Buffering, Suitable for Compact Design
Our high-hardness NBR/TPU material stepless buffer gasket is a cleverly conceived, simple yet crucial component, specifically designed for micro and dual-axis cylinders with extremely limited internal space. Unlike bulky traditional stepped buffers, this flat, high-performance gasket can directly provide effective deceleration and impact absorption at the end cap, ensuring smooth operation and significantly extending the service life of compact pneumatic actuators.
Ideal Applications: Mini cylinders, dual-axis cylinders, guided cylinders, and other compact pneumatic actuators where internal space is precious.
- True Step-Free Design: Ultra-thin, flat profile installs easily in cylinders with no room for conventional stepped buffers.
- Exceptional Wear Resistance: Made from high-grade NBR (Standard) or TPU (High-Performance), offering outstanding abrasion resistance for millions of cycles.
- High Hardness for Effective Damping: Specially formulated compounds provide the optimal hardness to absorb impact energy without compromising sealing.
- Reduced Noise & Vibration: Effectively dampens the metallic "clang" at end-of-stroke, creating quieter machinery.
- Easy Installation: A simple drop-in component that requires no modification to your cylinder.

- Choose NBR (Standard): For most general industrial applications. Excellent balance of cost and performance, with good resistance to lubricants and wear.
- Choose TPU (Premium): For high-cycle applications, higher speeds, or where maximum service life is critical. Superior abrasion resistance and mechanical strength.
This buffer gasket is essential in precision automation equipment using compact pneumatic actuators:
- Electronics Assembly: PCB handling, component insertion, mini pick-and-place units.
- Medical & Laboratory Automation: Diagnostic equipment, sample handling, precision fluid dispensing.
- Robotics: Small robotic grippers and end-effectors.
- Packaging Machinery: Small product sorting and positioning.
- Precision Instrumentation: Optical lens adjustment, sensor actuation.
