Rotary Shaft Seal 25x62x8 NBR AO Double Lip Oil Seal

Product Overview

The Rotary Shaft Seal 25x62x8 NBR AO is a high-performance radial shaft seal designed for reliable sealing of rotating shafts operating with lubricating oils and greases. The AO profile features a primary sealing lip with an integrated garter spring and a secondary dust lip, providing effective lubricant retention while protecting the sealing area from dust, dirt and moisture. Manufactured from premium NBR (Nitrile Butadiene Rubber), this seal delivers long service life and dependable performance in industrial machinery, automotive systems and OEM equipment.

Application in Industrial Systems

The Rotary Shaft Seal 25x62x8 NBR AO is suitable for:

• Industrial gearboxes
• Gear reducers
• Hydraulic pumps
• Water pumps
• Electric motors
• Compressors
• Industrial drive systems
• Agricultural machinery
• Construction equipment
• Manufacturing machinery
• OEM equipment
• Industrial maintenance operations

The AO profile is particularly suitable for applications exposed to dust, moisture and other environmental contaminants.

Construction and Design

The AO profile incorporates a primary sealing lip with an integrated garter spring and an additional dust lip. The spring maintains constant radial pressure on the shaft, while the dust lip prevents contaminants from entering the sealing area. The rubber-covered outer diameter ensures secure housing installation and reliable static sealing.

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
• Mechanical wear
• Abrasion
• Aging under normal operating conditions

Its excellent balance of flexibility, durability and cost efficiency makes NBR the preferred material for general industrial rotary shaft sealing applications.
