GRN Rotary Shaft Seal 80x100x12 NBR AO/TC Double Lip Oil Seal

Product Overview

The GRN Rotary Shaft Seal 80x100x12 NBR AO/TC is a premium radial shaft seal designed to provide reliable sealing for rotating shafts operating in industrial and automotive equipment. Manufactured from high-quality NBR (Nitrile Butadiene Rubber), it offers excellent resistance to lubricating oils, greases and mechanical wear. The AO/TC profile features a spring-loaded primary sealing lip and an additional dust lip, ensuring dependable lubricant retention while protecting the sealing area from dust, dirt and moisture.

Application in Industrial Systems

The GRN Rotary Shaft Seal is suitable for:

• Industrial gearboxes
• Gear reducers
• Hydraulic pumps
• Oil pumps
• Electric motors
• Compressors
• Industrial drive systems
• Agricultural machinery
• Construction equipment

The AO/TC profile is specifically designed for rotating equipment operating in dusty or contaminated environments where enhanced shaft protection is required.

Construction and Design

The AO/TC profile incorporates a rubber-covered outer diameter, a primary sealing lip with an integrated garter spring and a secondary dust lip. This double lip configuration effectively retains lubricants while preventing dust, moisture and abrasive particles from entering the sealing interface. The garter spring maintains constant radial pressure for consistent sealing performance throughout the service life.

Material Properties

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

NBR provides excellent resistance to:

• Mineral oils
• Gear oils
• Hydraulic fluids
• Lubricating greases
• Petroleum-based fuels
