The VAD-Type Universal Rod and Bore Seal is a symmetrical seal for both bore and shaft applications. It is a further development of the lip seal. The star ring acts as a radial force and compensates for seal lip wear. System pressure is transmitted to the sealing lip through the compressed and deformed star ring, resulting in excellent sealing performance at both high and low pressures. It is primarily used for sealing plungers, piston rods, forging machines, and hydraulic equipment used in mobile equipment. Materials: Polyurethane (PU) + Nitrile-butadiene rubber (NBR).
1. Insensitive to vibration loads and pressure spikes
2. Excellent extrusion resistance
3. Improved sealing performance under no-load conditions and at low temperatures
4. Suitable for harsh operating conditions
5. Long service life.
