GRN® Rotary Shaft Seal 55x80x10 NBR TC Double Lip Oil Seal

Product Overview

The GRN® Rotary Shaft Seal 55x80x10 NBR AO TC is a premium radial shaft seal engineered for reliable sealing of rotating shafts operating in oil and grease lubricated systems. Manufactured from high-quality NBR (Nitrile Butadiene Rubber), it provides excellent resistance to mineral oils, hydraulic fluids, lubricating greases and mechanical wear. The AO TC profile features a primary sealing lip with an integrated garter spring and an additional dust lip, ensuring reliable lubricant retention and effective protection against dust, dirt and moisture.

Designed for industrial and OEM applications, the seal provides long service life and dependable performance in demanding operating environments.

Applications

The GRN® Rotary Shaft Seal is suitable for:

• Industrial gearboxes
• Gear reducers
• Hydraulic pumps
• Oil pumps
• Electric motors
• Compressors

• Maintenance and repair operations

Its double lip construction is ideal for applications exposed to contamination and harsh operating conditions.

Construction and Design

The AO TC profile incorporates a spring-loaded primary sealing lip and an additional dust lip. The integrated garter spring maintains constant radial pressure against the shaft, ensuring effective lubricant retention, while the secondary lip prevents dust, mud, moisture and other contaminants from entering the sealing area.

This design significantly extends the service life of both the seal and the rotating shaft.

Material Properties

The seal is manufactured from premium NBR (Nitrile Butadiene Rubber).

NBR provides excellent resistance to:

• Mineral oils
• Hydraulic fluids
• Gear oils
• Lubricating greases
• Petroleum-based fuels
• Mechanical wear
• Abrasion
• Aging under normal operating conditions

Its durability and flexibility make NBR one of the most widely used elastomers for rotary shaft sealing applications.
