Description

The RWDR Kassette 178×205×17 NBR cassette oil seal by Suptex (Turkey) is a complete modular seal with a steel running surface and a sealing lip with a spring. An integrated grease-filled labyrinth protects against the ingress of contamination and mechanical damage. The cassette design eliminates the need to harden or grind the shaft, which makes installation easier and reduces maintenance costs. Intended for work in demanding conditions in hubs, gearboxes and reducers used in agricultural and construction machinery. Dimensions (mm / inch): Inner diameter (d1): 178 mm / 7.01'' Outer diameter (D): 205 mm / 8.07'' Height (B): 17 mm / 0.67'' Technical parameters: Material: NBR (acrylonitrile-butadiene rubber) + steel Design: RWDR cassette seal Permissible peripheral speed: ≤ 4 m/s Working pressure: ≤ 0,05 MPa

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.
