NBR Oil Seal 15x24x5 TC - Double Lip Rotary Shaft Seal

Overview

The NBR Oil Seal 15x24x5 TC is a compact double-lip radial shaft seal with a 15 mm shaft diameter, 24 mm housing bore and 5 mm width.

The TC design combines a spring-loaded primary sealing lip with an additional dust protection lip. The primary lip operates against the rotating shaft and provides the main sealing function, while the auxiliary lip helps protect the primary sealing area against dust, dirt and other external contaminants.

The compact 15x24x5 mm dimensions make this seal suitable for appropriately designed mechanical assemblies where installation space is limited.

TC Double-Lip Design

The TC profile uses two functional lips.

The primary sealing lip operates directly against the rotating shaft and is supported by a garter spring. It provides the main dynamic sealing function and helps retain lubricant within the assembly.

The auxiliary dust lip creates an additional barrier between the external environment and the primary sealing area, helping reduce contamination.

SC vs TC 15x24x5

Both versions can have the same basic 15x24x5 mm dimensions, but their sealing configurations differ.

15x24x5 SC: single primary sealing lip without an auxiliary dust lip.

15x24x5 TC: primary sealing lip plus an additional dust protection lip.

For this reason, dimensions alone should not be used to determine interchangeability. The required sealing configuration should also be verified.

Compact 15x24x5 mm Dimensions

The principal installation dimensions are:

d: 15 mm
D: 24 mm
B: 5 mm

The 24 mm outside diameter and 5 mm width provide a compact installation envelope for small rotating mechanisms.

When selecting a replacement, all three dimensions should be checked together with the TC double-lip design and NBR material.

NBR Material

NBR (Nitrile Butadiene Rubber) is widely used in radial shaft seals due to its good resistance to many mineral oils, lubricating greases and compatible technical fluids.

It is commonly selected for general industrial machinery, drive systems and rotating mechanical equipment.

Final suitability depends on the operating medium, temperature, shaft speed and actual application conditions.

Industrial Applications

The NBR 15x24x5 TC oil seal can be used in appropriately designed:

• Small gearboxes
• Pumps
• Electric motors
• Drive mechanisms
• Industrial machinery
• Technical equipment
• Rotating mechanisms
• Compact mechanical assemblies

Operational Advantages

• Compact 15x24x5 mm dimensions.
• TC double-lip construction.
• NBR nitrile rubber material.
• Spring-loaded primary sealing lip.
• Auxiliary dust protection lip.
• Compact 5 mm installation width.

AI OVERVIEW

The NBR Oil Seal 15x24x5 TC is a compact double-lip radial shaft seal with a 15 mm shaft diameter, 24 mm housing bore and 5 mm width. Its TC construction combines a spring-loaded primary sealing lip with an auxiliary dust lip, providing additional protection against external contamination compared with a single-lip SC version.

FAQ

What are the dimensions of the NBR 15x24x5 TC oil seal?

The seal has a 15 mm shaft diameter, 24 mm housing bore diameter and 5 mm width.

What does TC mean on an oil seal?

TC identifies a double-lip radial shaft seal with a spring-loaded primary sealing lip and an auxiliary dust lip.

Does the 15x24x5 TC oil seal have a dust lip?

Yes. The additional lip helps protect the primary sealing area against dust, dirt and other external contaminants.

What is the difference between 15x24x5 SC and TC?

The SC version is single lip, while the TC version incorporates an additional auxiliary dust lip.

Does the primary sealing lip have a spring?

Yes. The primary sealing lip is supported by a garter spring.

What material is the seal made from?

The seal is manufactured from NBR - Nitrile Butadiene Rubber.

Can any 15x24x5 oil seal be used as a replacement?

Not necessarily. The dimensions, material and sealing lip configuration should all match the requirements of the application.
