NBR Oil Seal 15x24x5 SC - Single Lip Rotary Shaft Seal

Overview

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

The SC design features a single primary sealing lip supported by a garter spring. The sealing lip operates directly against the rotating shaft and helps retain lubricant within the assembly. Unlike a double-lip TC seal, the SC configuration does not incorporate an additional auxiliary dust lip.

Its compact 15x24x5 mm dimensions make it suitable for appropriately designed mechanisms where radial and axial installation space is limited.

SC Single-Lip Design

The SC profile is a single-lip radial shaft seal configuration.

Its primary sealing lip operates against the rotating shaft and is supported by a garter spring to maintain sealing contact during operation.

The SC design does not have an additional dust protection lip. This distinguishes it from the TC double-lip configuration, which incorporates a secondary auxiliary lip.

Compact 15x24x5 mm Dimensions

The principal installation dimensions are:

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

The combination of a 24 mm outside diameter and 5 mm width provides a compact installation envelope for small rotating assemblies.

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

NBR Material

NBR (Nitrile Butadiene Rubber) is one of the most widely used elastomers for radial shaft seals.

It provides good resistance to many mineral oils, lubricating greases and compatible technical fluids. NBR seals are commonly used in general industrial machinery and mechanical drive systems.

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

Industrial Applications

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

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

Operational Advantages

• Compact 15x24x5 mm dimensions.
• SC single-lip construction.
• NBR nitrile rubber material.
• Spring-loaded primary sealing lip.
• Compact 5 mm installation width.
• Designed for a 15 mm shaft.

FAQ

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

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

What does SC mean on an oil seal?

SC identifies a single-lip radial shaft seal with a spring-loaded primary sealing lip.

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

No. The SC configuration does not incorporate 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?
