Description

The Shaft Seal 28.56x48x6 BAHDSN NBR [633B3209] is a product available in our online store lemming.shop. It is a high-pressure oil seal, which is used in hydraulic engines, used in hydrokinetic drives. Its construction is based on an open metal insert from the front side, which creates a stable contact surface. Thanks to this, the seal is protected from deformation under pressure. The seal is made of NBR, or nitrile rubber. The maximum working pressure is 150 bar, while the average working pressure is 100 bar. The maximum linear speed is 2 m/s. It is worth noting that oil seals marked with the symbols BAHD, BAHDSN and BAKHDSN are interchangeable and can be used interchangeably in the same applications. This product is designed to work in difficult conditions that require high reliability and durability of the seal. We invite you to purchase in our online store.

Material

NBR (nitrile butadiene rubber)

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

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.
