Rotary Shaft Seal 40x56x10 NBR AO/TC Double Lip Oil Seal

Overview

The Rotary Shaft Seal 40x56x10 NBR AO/TC is a high-quality radial shaft seal manufactured from durable NBR (Nitrile Butadiene Rubber). Designed for reliable sealing of rotating shafts, the AO/TC double lip design features a primary sealing lip with an integrated garter spring and an additional dust lip. This construction effectively retains lubricants while preventing dust, dirt and moisture from entering the sealing system. It provides dependable sealing performance and extended service life in industrial, automotive and OEM applications.

Industrial Applications

The Rotary Shaft Seal 40x56x10 NBR AO/TC is commonly used in:

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

It is designed for sealing rotating shafts operating with lubricating oils, greases and hydraulic fluids.

Construction

The AO/TC design incorporates a rubber-covered outer diameter, a primary sealing lip with an integrated garter spring and a secondary dust lip. This double lip construction improves sealing efficiency by preventing lubricant leakage while protecting the shaft and internal components against contaminants, moisture and abrasive particles.

Material

NBR (Nitrile Butadiene Rubber) is one of the most widely used elastomers for rotary shaft seals. It provides excellent resistance to:

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

Its excellent flexibility and durability make NBR an ideal material for general industrial sealing applications.
