Oil Seal 80x100x13 NBR TC/BASL - Shaft Seal GRN®

Application and Sealing Function

The 80x100x13 NBR TC/BASL GRN® oil seal is a high-quality radial shaft seal designed for reliable rotary sealing in industrial, automotive, and agricultural applications. The double lip design with an additional dust lip (BASL) provides effective protection against lubricant leakage and external contamination.

This shaft oil seal is commonly used in machines, gearboxes, engines, pumps, and hydraulic systems where durability, tightness, and operational stability are required under continuous rotation.

NBR Material and BASL Design - High Durability

The seal is manufactured from NBR (nitrile butadiene rubber), offering excellent resistance to oils and greases, mineral lubricants, and typical operating fluids. NBR is a proven material for oil seals used in demanding industrial environments.

The AO/BASL construction includes:

• a primary sealing lip with a garter spring, ensuring constant radial pressure on the shaft,

• a secondary dust lip, protecting the sealing zone from dirt and moisture,

• a metal-reinforced outer case, providing dimensional stability and secure seating in the housing.

This combination ensures long service life and consistent sealing performance.

Main Description

The 80x100x13 NBR AO/BASL GRN® oil seal is a professional technical sealing solution designed for long-term operation in rotating shaft applications. As a double lip oil seal, it effectively prevents oil leakage while shielding the sealing area from dust, moisture, and other contaminants.

Thanks to its NBR compound, the seal maintains stable performance when exposed to oils and greases commonly used in industrial and automotive systems. The integrated garter spring and metal reinforcement ensure reliable shaft contact and secure installation, even under variable operating conditions.

This product is intended for B2B customers, maintenance departments, and service workshops that require dimensional accuracy, consistent quality, and fast availability of shaft seals.

FAQ - Frequently Asked Questions

What is the difference between a double lip and single lip oil seal?
A double lip oil seal includes an additional dust lip that protects against external contamination.

Is NBR suitable for oil and grease applications?
Yes, NBR offers very good resistance to mineral oils and greases.

How do I select the correct oil seal size?
The inner diameter must match the shaft diameter - in this case, 80 mm.

Is this seal suitable for rotary shaft applications?
Yes, it is designed specifically for rotary sealing.
