Description

The NOK BD2694E oil seal is a high-quality oil seal intended for sealing rotating shafts in gearboxes, motors and other mechanisms, preventing oil/grease leaks and protecting against contamination. Seals of this type are widely used in the automotive industry, industrial machinery and mechanical equipment. Technical specification: Part number: BD2694E Inner diameter: 17 mm Outer diameter: 31 mm Width/thickness: 7 mm Materials: Rubber sealing lip - provides flexibility and resistance to oils and greases Metal support ring - stabilises the seal in the housing Garter spring - maintains constant pressure of the sealing lip on the shaft Applications: sealing of crankshafts, drive shafts and auxiliary shafts combustion and electric motors mechanical gearboxes and transmissions pumps and industrial machinery agricultural and construction equipment Features and benefits: Effective retention of oil and other lubricating fluids Reduced ingress of contamination and moisture Minimised friction between the seal and the shaft Durability and resistance to standard operating conditions (oils)

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.
