Description

The High-Pressure Simmering 49.21x68.22x9.53 BAHD NBR TTO is a specialist shaft seal used in hydraulic engines. These engines are often used in hydrokinetic drives, where exceptional durability and resistance to high pressure are required. This simmering is characterized by an open metal insert on the front side, providing a stable contact surface. As a result, the seal is protected from deformation under pressure, which is crucial when operating under high-pressure conditions. The product is made of NBR, or nitrile rubber, a material highly resistant to various external factors. The maximum working pressure of the simmering is 150 bar, while the average working pressure is 100 bar. The maximum linear speed that this seal can achieve is 2 m/s. It's worth noting that simmerings 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 provide the appropriate reliability and durability of the seal, even under the most demanding conditions. Purchasing the High-Pressure Simmering 49.21x68.22x9.53 BAHD NBR TTO is an investment in the reliability and durability of your hydraulic engine.

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)

Shows low compression set within the recommended temperature range.
