Rotary Shaft Seal 115x160x15 NBR TC - Double Lip Oil Seal

Reliable sealing for industrial rotary applications

High durability and resistance to oils and grease

Main description

The Rotary Shaft Seal 115x160x15 NBR TC Double Lip is a professional oil seal engineered for dependable rotary shaft sealing in demanding industrial applications and automotive systems. Its primary role is to retain lubricants such as oils and greases within the system while preventing external contaminants from entering the sealing zone.

This double lip oil seal (TC) features a spring-loaded primary sealing lip that maintains constant radial pressure against the shaft, ensuring stable sealing performance over time. A secondary dust lip provides additional protection against dirt, moisture, and abrasive particles. Compared to a single lip oil seal (SC), the TC configuration offers enhanced contamination protection and longer service life, especially in harsh operating environments.

Manufactured from NBR (nitrile butadiene rubber), the seal delivers excellent resistance to oils and grease, fuels, and standard hydraulic fluids. NBR is widely used in technical seals due to its elasticity, wear resistance, and dimensional stability. The reinforced construction with a metal case ensures secure press-fit mounting, vibration damping, and high durability during continuous operation.

With dimensions of 115x160x15 mm, this shaft sealing ring is compatible with standard housings and shafts used in gearboxes, pumps, electric motors, and heavy machinery. It functions effectively as a rotary seal, engine seal, and shaft seal in systems exposed to variable pressures and temperatures. The design supports reliable performance in both industrial machinery and hydraulic and automotive seals applications.

Quality, consistency, and repeatable performance are associated with the GRN product range, trusted by B2B customers for robust sealing solutions.

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 extending service life.

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

Is NBR suitable for oil and grease sealing?
Yes, NBR offers very good resistance to mineral oils, greases, fuels, and common technical fluids.

How do I select the correct rotary shaft seal size?
The inner diameter must match the shaft (115 mm), the outer diameter the housing (160 mm), and the width must fit the installation space (15 mm).

Where are 115x160x15 TC oil seals commonly used?
They are widely used in gearboxes, pumps, engines, industrial machinery, and heavy-duty drive systems.
