Oil Seal NBR 65x85x10 TC - Double Lip Rotary Shaft Seal GRN

Applications in Agricultural and Industrial Machinery

The 65x85x10 NBR AO/TC oil seal by GRN is a professional rotary shaft seal designed for reliable shaft sealing in agricultural machinery and industrial equipment. It is commonly used in gearboxes, axles, hydraulic systems, and drive units where effective oil retention and contamination protection are essential.

This double lip oil seal is particularly suitable for machines operating in dusty, muddy, and variable outdoor conditions, making it a proven choice for tractors, harvesters, and other agricultural applications.

NBR Material and AO/TC Design - High Durability

The seal is manufactured from NBR (nitrile butadiene rubber), a material known for its excellent resistance to oils and grease, hydraulic fluids, and common lubricants. NBR provides good elasticity, dimensional stability, and long service life under standard operating temperatures.

The AO/TC design indicates a double lip shaft seal:

• the primary sealing lip with a garter spring ensures reliable oil sealing,

• the secondary lip acts as a protective barrier against dust and dirt.

This construction significantly improves technical sealing performance and reduces the risk of premature wear.
