Description
The 28.56x39x5 BAHD NBR Shaft Seal is a product that finds application in hydraulic engines used in hydrokinetic drives. Its construction includes an open metal insert on the front side, providing a stable contact surface and protecting against deformation under pressure. The seal is made of NBR, or nitrile rubber. This is a material highly resistant to oils and greases, making it ideal for use in hydraulic engines. The maximum working pressure is 150 bar, and the average working pressure is 100 bar. The maximum linear speed is 2 m/s, which means that the seal can withstand rapid shaft movements. 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 need to replace the seal in your hydraulic engine, you can choose any of these models. The product is designed to work in difficult conditions where high reliability and durability of the seal are required. Thanks to its properties, the 28.56x39x5 BAHD NBR shaft seal is an excellent choice for anyone looking for a reliable and durable solution for their 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.
| 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.
