Diaphragm Rod Seal – Low-Friction Membrane Seal for High-Sensitivity Pneumatic and Light Hydraulic Applications.
Diaphragm rod seal with flexible membrane design for low-friction, high-sensitivity applications. Minimal breakout, misalignment-tolerant. NBR/FKM/Silicone, –40°C~120°C, ≤10 MPa.
Diaphragm Rod Seal – A precision-engineered low-friction membrane seal designed for rod applications requiring minimal breakout friction and high sensitivity. This flexible diaphragm seal features an elastomeric membrane that provides uniform sealing contact with exceptionally low drag, ensuring smooth response even at low pressures. The resilient construction accommodates minor rod misalignment and eccentricity without compromising sealing integrity, while the high-elasticity compound delivers excellent resistance to media permeation and pressure cycling. This high-sensitivity rod seal is ideal for pneumatic cylinders, instrumentation, medical devices, and low-pressure hydraulic systems where friction sensitivity and precision motion control are critical. Material: high-elasticity NBR, FKM, or silicone compound. Temp: –40°C to +120°C. Pressure: up to 10 MPa. Speed: up to 1 m/s.
