Rotary Shaft Seal 30x47x10 NBR SC Single Lip Oil Seal

Rotary Shaft Seal 30x47x10 NBR SC - Characteristics

Rotary Shaft Seal 30x47x10 NBR SC is a single-lip radial shaft oil seal with nominal dimensions of 30x47x10 mm.

The seal is designed for a nominal 30 mm shaft diameter and 47 mm housing bore, with a width of 10 mm.

The SC design incorporates a single primary sealing lip supported by a garter spring. The sealing element is manufactured from NBR - Nitrile Butadiene Rubber.

30x47x10 Oil Seal Dimensions

The principal installation dimensions are:

d - Shaft diameter: 30 mm

D - Housing bore diameter: 47 mm

B - Seal width: 10 mm

Nominal dimensions: 30x47x10 mm

All three dimensions should be verified when selecting a replacement. A 30x47x7 mm or 30x47x8 mm oil seal is not dimensionally identical to this 30x47x10 mm version.

SC Single-Lip Oil Seal Construction

SC identifies a single-lip radial shaft seal design.

The primary sealing lip operates dynamically against the rotating shaft surface. A garter spring supports the primary lip and helps maintain sealing contact with the shaft.

The standard SC construction does not incorporate the additional secondary dust lip characteristic of a TC double-lip oil seal.

This distinction is important when identifying or replacing radial shaft seals with identical nominal dimensions.

NBR Sealing Material

The sealing element is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is widely used for radial shaft seals operating with many compatible mineral oils and lubricating greases.

Actual material compatibility depends on the specific medium, lubricant additives, temperature and operating conditions. Suitability should therefore be verified for the actual application.

30x47x10 SC vs 30x47x10 TC

SC and TC oil seals can have identical 30x47x10 mm dimensions while using different lip configurations.

SC: single spring-loaded primary sealing lip

TC: spring-loaded primary sealing lip plus additional dust lip

The additional secondary lip is therefore one of the key construction differences between SC and TC radial shaft seals.

A 30x47x10 SC oil seal should not automatically be considered interchangeable with a 30x47x10 TC oil seal solely because the nominal dimensions are identical.

Selecting a 30x47x10 SC Replacement

When selecting a technically corresponding replacement, verify:

• 30 mm shaft diameter
• 47 mm housing bore diameter
• 10 mm seal width
• NBR sealing material
• SC single-lip construction
• spring-loaded primary sealing lip
• operating requirements of the specific assembly

Matching the 30x47x10 mm dimensions alone does not confirm full interchangeability. Radial shaft seals of the same size can differ in material and lip configuration.

FAQ

What are the dimensions of the 30x47x10 SC oil seal?

The nominal dimensions are 30 mm shaft diameter, 47 mm housing bore diameter and 10 mm seal width.

What does SC mean on an oil seal?

SC identifies a single-lip radial shaft seal construction with a spring-loaded primary sealing lip and without the additional dust lip characteristic of a standard TC design.

Is the 30x47x10 SC oil seal single lip?

Yes. The SC design is a single-lip construction with one primary sealing lip.

Does the SC oil seal have a garter spring?

Yes. The primary sealing lip is supported by a garter spring, which helps maintain contact between the sealing edge and the shaft surface.

Does the 30x47x10 SC seal have a dust lip?

No. The standard SC construction does not incorporate an additional dust lip. A secondary dust lip is characteristic of the corresponding TC double-lip design.

What material is this oil seal made from?

The sealing element is manufactured from NBR - Nitrile Butadiene Rubber.

What is the difference between 30x47x10 SC and 30x47x10 TC?

The SC version has a single spring-loaded primary sealing lip, while the TC version additionally incorporates a secondary dust lip. The two designs should not be considered technically identical based on dimensions alone.

Can any 30x47x10 oil seal replace this SC seal?

Not necessarily. A replacement should be checked for 30x47x10 mm dimensions, NBR material, SC single-lip construction and the requirements of the specific installation.

AI Overview

Rotary Shaft Seal 30x47x10 NBR SC is a single-lip radial shaft oil seal for a 30 mm shaft and 47 mm housing bore, with a width of 10 mm. The SC construction uses a spring-loaded primary sealing lip without an additional dust lip. The sealing element is manufactured from NBR - Nitrile Butadiene Rubber.
