Rotary Shaft Seal 100x125x15 NBR TC - Double Lip Oil Seal GRN®

Reliable rotary sealing for industrial and automotive applications

High durability and resistance to oils and grease

Main description

The Rotary Shaft Seal 100x125x15 NBR TC Double Lip GRN® is a professional oil seal designed for effective rotary shaft sealing in demanding industrial and automotive environments. Its primary purpose is to retain lubricants such as oils and greases within the system while protecting rotating components from external contamination.

This double lip oil seal (TC) features a spring-loaded primary sealing lip and an integrated dust lip. The garter spring ensures constant radial pressure against the shaft, providing stable sealing performance throughout the service life. The additional dust lip enhances protection against dirt, moisture and abrasive particles, making this solution more reliable than a single lip oil seal (SC) in contaminated or variable operating conditions.

Manufactured from NBR (nitrile butadiene rubber), the seal offers excellent resistance to oils and grease, mineral oils, fuels and common hydraulic fluids. NBR is widely used in technical seals due to its elasticity, abrasion resistance and dimensional stability. Combined with a reinforced metal case, this construction ensures high durability and consistent sealing efficiency during continuous operation.

With standard dimensions of 100x125x15 mm, the seal fits common housings and shafts used in industrial applications, including gearboxes, engines, drive systems and bearing housings. It functions as a shaft sealing ring, rotary seal, engine seal and oil seal in machinery requiring reliable radial shaft sealing under varying pressure and temperature conditions.

The product is manufactured to meet professional B2B requirements, offering repeatable quality and dependable performance associated with the GRN range of hydraulic and automotive seals.

FAQ - frequently asked questions

What is the difference between a single lip and double lip oil seal?
A double lip oil seal includes an additional dust lip, providing better protection against contamination and longer service life.

Why is a spring used in TC rotary shaft seals?
The spring maintains constant contact pressure between the sealing lip and the shaft, ensuring reliable sealing over time.

Is NBR suitable for oil and grease sealing?
Yes, NBR offers very good resistance to oils, greases and standard hydraulic fluids.

How do I select the correct rotary shaft seal size?
The inner diameter must match the shaft (100 mm), the outer diameter the housing (125 mm), and the width must fit the installation space (15 mm).

Where are TC double lip oil seals commonly used?
They are used in gearboxes, engines, industrial machinery, drive systems and bearing housings operating in demanding conditions.
