Description

The Simmering 125x180x13/16x51 BDOFSLFSFX7 NBR gearbox shaft seal is an essential component for any concrete mixer. It has been designed to ensure tightness within the drive shaft of the planetary gearbox, even under the most challenging working conditions. Product features: Material: NBR Application: Compatible with gearboxes used in concrete mixers Resistance: High resistance to wear and aggressive working environment Type of seal: Lip oil seal made of oil and temperature resistant elastomer Function: Prevents oil leaks and the ingress of contaminants into the gearbox The seal is compatible with gearboxes from manufacturers such as: Bonfiglioli, ZF, Rexroth, RR Holland (Reggiana Riduttori). The gearbox shaft seal is a key element in maintaining the durability and trouble-free operation of the drive gearbox that drives the rotation of the mixing tank.

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.
