Technical Specifications

Description & Advantages

 

The NS-77 GGDI captive slide and o-ring seal for ouside sealing is a compact element for sealing piston rods .It can be used with mineral oils, water base fluids, and in modified form with other fluids.The GGDI seal consists of 4 parts, a sharp egded sealing ring of PTFE compound, 2 L-shaped support ring ofPOM 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. ring provides the sealing function, being pressed against the piston rod by the O-ring energiser.Due to its excellent sliding characteristics, measurable wear cannot be detected even after millions of stroke cycles.
