Description

The 28.6x39x4.9 BAKHDSN 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, which provides a stable contact surface and protects against 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 simmerings 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, where high reliability and durability of the seal are required. We invite you to purchase the 28.6x39x4.9 BAKHDSN NBR shaft seal in our online store at lemming.shop. We guarantee quick order processing and professional service.

Material

NBR (nitrile butadiene rubber)

Operating temperature-30 °C to +100 °C

Chemical resistance
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)
