GRN 100x130x12 NBR SC Single Lip Oil Seal

GRN 100x130x12 NBR SC is a single lip radial shaft oil seal with nominal dimensions of 100x130x12 mm.

The sealing material is:

GRN reference:

100X130X12 A

The seal incorporates a spring-loaded primary sealing lip and does not have an additional dust lip.

Complete product identification:

GRN -> 100X130X12 A -> 100x130x12 mm -> NBR -> SC -> single lip radial shaft oil seal

100x130x12 Oil Seal Dimensions

The principal dimensions are:

d - Inside diameter / shaft diameter: 100 mm

D - Outside diameter: 130 mm

B - Width: 12 mm

Dimensions: 100x130x12 mm

The first dimension corresponds to the nominal shaft diameter, the second to the outside diameter and the third to the seal width.

All three dimensions should be verified when selecting a replacement.

SC Single Lip Oil Seal Design

The SC designation is used here for the English identification of the single lip version.

The seal incorporates:

primary sealing lip

garter spring

no additional dust lip

The primary sealing lip forms the dynamic sealing interface with the rotating shaft.

The garter spring helps maintain radial contact between the sealing lip and the shaft surface.

The single lip configuration is the principal construction feature distinguishing this product from the corresponding AO/TC double lip version.

Single Lip Oil Seal Without an Additional Dust Lip

GRN 100x130x12 NBR SC is a single lip oil seal.

It does not incorporate the additional dust lip found on the corresponding 100x130x12 AO/TC double lip seal.

This difference should be considered when identifying or selecting the correct seal.

Two oil seals can have exactly the same 100x130x12 mm dimensions while having different lip configurations.

NBR Sealing Material

The sealing material is:

NBR - Nitrile Butadiene Rubber

NBR is widely used in radial shaft sealing applications and is commonly used with many compatible mineral oils and lubricating greases.

Exact compatibility depends on the specific medium, additives, temperature and operating conditions.

A fixed maximum operating temperature, pressure, shaft speed or material hardness should not be assigned to this exact GRN product solely from general NBR data or specifications for seals from other manufacturers.

100x130x12 SC vs 100x130x12 AO/TC

The 100x130x12 SC and 100x130x12 AO/TC oil seals have the same nominal dimensions but different lip configurations.

100x130x12 SC - single lip:

• spring-loaded primary sealing lip
• no additional dust lip

100x130x12 AO/TC - double lip:

• spring-loaded primary sealing lip
• additional dust lip

The dimensions alone therefore do not distinguish these two versions.

The required lip configuration should also be verified before selecting a replacement.

100x130x12 vs 100x130x13 Oil Seal

The 100x130x12 and 100x130x13 oil seals share the same nominal inside and outside diameters but differ in width.

100x130x12: 12 mm width

100x130x13: 13 mm width

The 1 mm difference in width should not be ignored when selecting a replacement.

The required width should correspond to the original seal and the specific installation.

GRN 100x130x12 SC vs CORTECO 12011057B BA

GRN 100x130x12 SC and CORTECO 12011057B BA share the same nominal dimensions:

100x130x12 mm

Both are specified with NBR sealing material, but they use design terminology associated with their respective product identification:

GRN: A / SC single lip

CORTECO 12011057B: BA

Matching dimensions and sealing material alone should not be treated as confirmation of complete interchangeability.

The exact seal construction and requirements of the specific installation should also be verified.

How to Select a 100x130x12 Single Lip Oil Seal

When selecting a replacement, verify:

• 100 mm shaft diameter
• 130 mm outside diameter
• 12 mm width
• NBR sealing material
• single lip construction
• spring-loaded primary sealing lip
• absence of an additional dust lip
• requirements of the specific installation

Matching the 100x130x12 mm dimensions alone does not confirm full interchangeability.

Oil seals with identical dimensions may differ in material, lip configuration and other construction characteristics.

FAQ

What are the dimensions of the GRN 100x130x12 oil seal?

The seal has a 100 mm inside diameter, 130 mm outside diameter and 12 mm width. Its nominal dimensions are 100x130x12 mm.

Is the GRN 100x130x12 SC oil seal single lip?

Yes. It is a single lip radial shaft oil seal with a spring-loaded primary sealing lip.

Does the 100x130x12 SC oil seal have a spring?

Yes. The primary sealing lip is equipped with a garter spring that helps maintain contact between the sealing lip and the shaft surface.

Does the SC design have an additional dust lip?

No. This SC single lip version does not incorporate an additional dust lip.

What material is the 100x130x12 oil seal made from?

The seal is manufactured from NBR - Nitrile Butadiene Rubber.

Can NBR be used with oil?

NBR is commonly used with many compatible mineral oils and lubricating greases. Exact compatibility depends on the specific medium, additives, temperature and operating conditions.

What is the difference between 100x130x12 SC and 100x130x12 AO/TC?

SC is a single lip design with a spring-loaded primary sealing lip and no additional dust lip. AO/TC is a double lip design with a spring-loaded primary sealing lip and an additional dust lip.

Are 100x130x12 SC and 100x130x12 AO/TC the same size?

Yes. Both versions have nominal dimensions of 100x130x12 mm, but their lip configurations are different.

What is the difference between 100x130x12 and 100x130x13 oil seals?

Both have a nominal 100 mm inside diameter and 130 mm outside diameter. The difference is the width: one is 12 mm wide, while the other is 13 mm wide.

Is GRN 100x130x12 SC the same as CORTECO 12011057B BA?

Complete interchangeability should not be assumed solely from the dimensions and NBR material. The products use different manufacturer-specific design identification, and the exact construction and application requirements should be verified.

Can any 100x130x12 single lip oil seal replace this GRN seal?

Not necessarily. A replacement should match the 100x130x12 mm dimensions, NBR material, single lip construction and spring-loaded primary sealing lip. Requirements of the specific installation should also be verified.
