UN profile flange rings
Flange rings with negative lip are the most widely used, as a rod or piston seal, in alternating movements:
- Operating pressures: < 400 bar
- Temperatures: from -40 to +80ºC.
- Displacement speed: < 0.4 m/sec.
Flange rings with negative lip are the most widely used, as a rod or piston seal, in alternating movements:
This flange ring brushes the smooth, clean walls of the rods in alternating or rotating movements, and is designed to prevent dirt from entering the interior of the hydraulic equipment, keeping the shafts that protrude to the exterior clean at all times.
These are flange rings derived from U or UN types, but with the outer lip larger than the inner lip. Assembly is the same as for UN flange rings.
These are flange rings derived from U or UN types, but with the inner lip larger than the outer lip. The assembly mounting, located in the interior and larger than the closure mounting, ensures a water-tight, fixed position in the piston housing.
