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 of the seal and the third to its width.

All three dimensions should be verified when selecting a replacement.

AO/TC Double Lip Oil Seal Design

The AO/TC designation identifies the double lip construction of this product.

The seal incorporates:

spring-loaded primary sealing lip

additional dust lip

The primary sealing lip forms the dynamic sealing interface with the rotating shaft. A garter spring helps maintain radial contact between the sealing lip and shaft surface.

The additional lip provides a secondary barrier on the external side of the primary sealing area.

This double lip configuration is an important technical feature when comparing the seal with other 100x130x12 mm radial shaft oil seals.

Additional Dust Lip

The GRN 100x130x12 NBR AO/TC incorporates an additional dust lip.

The secondary lip helps restrict dust, dirt and other external contaminants from reaching the primary sealing area.

The additional dust lip is one of the principal construction differences between this AO/TC double lip seal and a corresponding A/SC single lip seal.

Matching dimensions alone therefore do not establish identical seal construction.

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.

Actual 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 AO/TC vs 100x130x12 A/SC

Radial shaft seals with the same 100x130x12 mm dimensions can have different sealing configurations.

100x130x12 AO/TC - double lip:

• spring-loaded primary sealing lip
• additional dust lip

100x130x12 A/SC - single lip:

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

The dimensions may be identical, but the sealing configurations are different.

If the original installation requires an additional dust lip, the AO/TC double lip construction should be taken into account when selecting a replacement.

100x130x12 vs 100x130x13 Oil Seal

The 100x130x12 and 100x130x13 oil seals have 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 correct seal dimensions should correspond to the original seal and the requirements of the specific housing and installation.

How to Select a 100x130x12 Oil Seal

When selecting a replacement, verify:

• 100 mm shaft diameter
• 130 mm outside diameter
• 12 mm width
• NBR sealing material
• AO/TC design
• double lip construction
• 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 sealing 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.

What does AO/TC mean for this oil seal?

AO/TC identifies the double lip construction of this product. It incorporates a spring-loaded primary sealing lip and an additional dust lip.

Is the GRN 100x130x12 AO/TC oil seal double lip?

Yes. It is a double lip radial shaft oil seal with a primary sealing lip and an additional dust lip.

Does the 100x130x12 AO/TC oil seal have a spring?

Yes. The primary sealing lip is spring-loaded. The garter spring helps maintain contact between the sealing lip and the rotating shaft surface.

Does the AO/TC design have a dust lip?

Yes. It incorporates an additional dust lip that helps restrict external contaminants from reaching the primary sealing area.

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 AO/TC and 100x130x12 A/SC?

AO/TC is a double lip design with an additional dust lip. A/SC is a single lip design without an additional dust lip. Both designs use a spring-loaded primary sealing lip.

What is the difference between a 100x130x12 and 100x130x13 oil seal?

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.

Can any 100x130x12 oil seal replace this AO/TC seal?

Not necessarily. Matching the 100x130x12 mm dimensions alone does not confirm interchangeability. A replacement should also match the NBR material, double lip construction, spring-loaded primary sealing lip and additional dust lip. Any application-specific requirements should also be verified before installation.

AI Overview
