Technical Specifications

Description & Advantages

The NS-19 GGDA captive slide and o-ring seal for outside sealing is a compact element for sealing cylinder pistons. It can be used with mineral oils and in modified form with water base fluids, fire resistant fluids, and compressed air. The GGDA seal consists of 4 parts, a sharp egded sealing ring of PTFE- Bronze compound, 2 L-shaped support ring of POM and an O-ring as energiser. The L-shaped rings firmly support and guide the slide ring to ensure a tight seal at all times. The slide ring provides the sealing function, being pressed against the cylinder wall by the O-ring energiser. Due to its excellent sliding characteristics, measurable wear cannot be detected even after millions of stroke cycles.
