Description
The High-Pressure Seal 28.56x42x5.5 BAKHDSN NBR is a specialized sealing element used in hydraulic engines. Thanks to its design, this seal can withstand high working pressure, making it an ideal solution for hydrokinetic drives. This seal is characterized by an open metal insert on the front side, providing a stable contact surface. This design protects the seal from deformation under pressure, which is crucial for maintaining its full functionality. The seal is made of NBR, or nitrile rubber, a material highly resistant to various external factors. The maximum working pressure of this seal is 150 bar, while the average working pressure is 100 bar. The maximum linear speed it can withstand 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 if you're looking for a seal with similar parameters but from a different brand, these models will be suitable for you. This product is designed to work under tough conditions where high reliability and durability of the seal are required. Therefore, this seal is the perfect solution for those looking for reliable and durable sealing elements for their machines.
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.
