Description

The High-Pressure Seal 65x85x7 BAHDSN NBR is a specialist shaft seal used in hydraulic engines. These engines are often used in hydrokinetic drives, where the reliability and durability of the seal are key. This seal is characterized by an open metal insert on the front side, which forms a stable contact surface. This makes it resistant to deformation under pressure, which is particularly important when operating under high pressure. The product is made of NBR, or nitrile rubber. This material is known for its durability and resistance to various external factors. The 65x85x7 BAHDSN NBR seal can withstand a maximum working pressure of 150 bars. The average working pressure at which this product can operate is 100 bars. The maximum linear speed it can achieve is 2 m/s. It's worth noting that seals marked with the symbols BAHD, BAHDSN, and BAKHDSN are interchangeable and can be used interchangeably in the same applications. This means that regardless of the specific model, each will be able to perform its task under similar conditions. This product is designed to work in difficult conditions, where high reliability and durability of the seal are required. Thanks to its properties, the 65x85x7 BAHDSN NBR seal can meet even the most demanding tasks.

Material

NBR (nitrile butadiene rubber)

  • Operating temperature-30 °C to +100 °C

Good with oils, fuels, water and compressed air. Not for brake fluid, solvents, strong acids or sunlight.

Chemical resistance
Can be usedDo not use
Mineral oil, grease and hydraulic oil (H, H-L, H-LP)Brake fluid (DOT 3, DOT 4, DOT 5.1): the ring swells quickly
Diesel, fuel oil, keroseneSunlight and open air (ozone): the rubber cracks
Petrol (gasoline), propane, butaneAcetone, MEK, ethyl acetate and similar solvents
Water and water-based liquids, up to +80 °CBenzene, toluene, trichloroethylene (aromatic and chlorinated solvents)
Compressed air, also with oil mistSynthetic ester oils and fire-resistant fluid HFD-R
Water-based fire-resistant hydraulic fluids (HFA, HFB, HFC)Strong (concentrated) acids, e.g. nitric and sulfuric, and strong oxidizers
Oil-and-water emulsionsSteam and hot water above +100 °C
Weak acids, alkalis and salt solutions, at room temperature
Use with cautionPetrol with a lot of bioethanol (E10, E85): better use FKM (Viton)
