Description

The 28,56x48x6 BAHDSN NBR shaft seal is a high-pressure oil seal designed for hydraulic motors used in hydrokinetic drives. It has an open metal insert on the front face, which provides a stable contact surface and protects the seal from deformation under pressure. Made of NBR (nitrile rubber), it is resistant to oils and greases. Dimensions: 28,56 x 48 x 6 mm (d1 x D x b) 1.125" x 1.890" x 0.236" Technical data: Material: NBR (nitrile rubber) Type: BAHDSN Maximum working pressure: 150 bar Average working pressure: 100 bar Maximum linear speed: 2 m/s Replacements: BAHD, BAHDSN, BAKHDSN Applications: Shaft sealing in hydraulic motors Hydrokinetic drives

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.
