Oil Seal 52x72x10 NBR AO/TC - Shaft Seal GRN®

Application and Sealing Function

The 52x72x10 NBR AO/TC GRN® oil seal is a high-quality radial shaft seal designed for reliable rotary sealing in industrial, automotive, and agricultural applications. The double lip AO/TC design ensures effective oil retention while protecting the sealing area against external contaminants such as dust and moisture.

This shaft seal is commonly used in machines, engines, gearboxes, and drive systems where stable sealing performance and long service life are required under continuous rotational movement.

NBR Material and AO/TC 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 one of the most widely used materials for oil seals due to its durability and reliable performance in standard industrial conditions.

The AO/TC construction includes:

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

• a secondary protective lip that limits the ingress of contaminants,

• a rigid structure ensuring secure seating in the housing.

This design provides stable sealing and reduced wear over extended operating periods.

Main Description

The 52x72x10 NBR AO/TC GRN® oil seal is a professional technical sealing solution developed for long-term operation in rotating shaft applications. As a double lip oil seal, it effectively prevents oil leakage while protecting the internal sealing zone from external contamination.

Thanks to its NBR compound, the seal maintains consistent performance when exposed to oils and greases commonly used in industrial and automotive systems. The integrated garter spring ensures continuous contact with the shaft, supporting reliable sealing even under variable operating conditions.

This product is intended for B2B customers, maintenance departments, and service workshops that require dimensional accuracy, repeatable 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 protective lip that helps prevent contamination from entering the sealing area.

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, 52 mm.

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