Oil Seal NBR 85x110x13 AO - Double Lip Rotary Shaft Seal for Agriculture

Applications in Agriculture and Industrial Machinery

The NBR 85x110x13 AO oil seal is a professional rotary shaft seal designed for effective shaft sealing in agricultural machinery and selected industrial applications. It is commonly used in gearboxes, drive axles, hubs, working shafts, and hydraulic assemblies operating in harsh environments with dust, moisture, and variable loads.

Thanks to its double lip design, this oil seal is well suited for tractors, harvesters, tillage machines, presses, and other agricultural equipment where reliable oil retention and contamination protection are essential.

NBR Material and AO Design - High Durability

The seal is manufactured from NBR (nitrile butadiene rubber), a widely used material in oil seals due to its excellent resistance to oils and grease, fuels, and hydraulic fluids. NBR provides good elasticity, dimensional stability, and long service life under typical agricultural operating temperatures.

The AO design indicates a double lip oil seal, where:

• the primary sealing lip ensures effective oil retention,

• the secondary lip provides additional protection against dirt and contaminants.

This construction significantly improves technical sealing performance and extends the service life of the sealing system.
