Description

The RTAB 85×97×8,5 NBR rotary ring is intended for slow-rotation applications, in particular as a replacement for the Parker C1-type seal. Used in slew columns, bearings, gearboxes and other components requiring a radial dynamic seal. Made of NBR elastomer, it provides basic resistance to mineral oils and greases. Technical properties Material: NBR Type: RTAB rotary ring Replacement for: C1-type seal (Parker) Application: slow-rotation radial seals Installation in housings designed for the C1 profile Dimensions Inner diameter (d): 85 mm Outer diameter (D): 97 mm Height (H): 8,5 mm Dimensions in inches (d×D×H): 3.35" × 3.82" × 0.33"

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.
