Description
The High-Pressure Simmering 64.8x85x7 BAKHDSN NBR is a specialist shaft seal used in hydraulic engines. These engines are often used in hydrokinetic drives, where reliability and precision are key. This simmering is characterized by an open metal insert on the front side. This creates a stable contact surface that protects against deformation under pressure. This solution ensures optimal sealing performance, even under difficult working conditions. The product is made of NBR, or nitrile rubber. This material is resistant to oils and greases, making it ideal for use in hydraulic engines. The Simmering 64.8x85x7 BAKHDSN NBR can withstand a maximum working pressure of up to 150 bars. The average working pressure is 100 bars, and the maximum linear speed is 2 m/s. It's worth noting that simmerings marked with the symbols BAHD, BAHDSN, and BAKHDSN are interchangeable. This means they can be used interchangeably in the same applications. This product is designed to work under difficult conditions, where high reliability and durability of the seal are required. Therefore, the Simmering 64.8x85x7 BAKHDSN NBR is a choice that will meet the expectations of even the most demanding users.
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.
| Can be used | Do 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, kerosene | Sunlight and open air (ozone): the rubber cracks |
| Petrol (gasoline), propane, butane | Acetone, MEK, ethyl acetate and similar solvents |
| Water and water-based liquids, up to +80 °C | Benzene, toluene, trichloroethylene (aromatic and chlorinated solvents) |
| Compressed air, also with oil mist | Synthetic 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 emulsions | Steam 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.
