100x125x13 Oil Seal Dimensions

The principal dimensions are:

d - Inside diameter / shaft diameter: 100 mm

D - Outside diameter: 125 mm

B - Width: 13 mm

Dimensions: 100x125x13 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.

AO/TC Double Lip Oil Seal Design

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

The seal incorporates:

primary sealing lip

garter spring

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 primary sealing lip and the shaft surface.

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

Additional Dust Lip

GRN 100x125x13 NBR AO/TC incorporates an additional dust lip.

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

This is an important construction characteristic when comparing this product with other 100x125x13 mm radial shaft oil seals.

Matching dimensions alone do not establish identical sealing construction.

NBR Sealing Material

The sealing material is:

NBR - Nitrile Butadiene Rubber

NBR is widely used as an elastomeric material for radial shaft oil seals.

It is commonly used with many compatible mineral oils and lubricating greases.

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

A specific maximum temperature, pressure, shaft speed or material hardness should not be assigned to this exact GRN product without confirmation for the specific seal specification.

100x125x13 AO/TC vs Single Lip Oil Seal

The AO/TC version is a double lip oil seal.

Its construction incorporates:

spring-loaded primary sealing lip

and

additional dust lip

A corresponding single lip design does not incorporate the additional dust lip.

This distinction is important because oil seals with identical nominal dimensions may use different lip configurations.

100x125x13 vs 100x125x14 Oil Seal

The 100x125x13 and 100x125x14 oil seals have the same nominal inside and outside diameters:

d = 100 mm

D = 125 mm

Their widths are different:

100x125x13: B = 13 mm

100x125x14: B = 14 mm

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

100x125x13 vs 100x125x12 Oil Seal

The 100x125x13 and 100x125x12 sizes share the same nominal 100 mm shaft diameter and 125 mm outside diameter.

They differ in width:

100x125x13: B = 13 mm

100x125x12: B = 12 mm

Matching the first two dimensions therefore does not mean that the two oil seals are dimensionally identical.

100x125x13 vs 100x125x15 Oil Seal

The 100x125x15 mm version differs from this product in width.

100x125x13: width 13 mm

100x125x15: width 15 mm

The complete dimensions of the original seal should therefore be verified before ordering a replacement.

How to Select a 100x125x13 Oil Seal

When selecting a replacement, verify:

• 100 mm shaft diameter
• 125 mm outside diameter
• 13 mm width
• NBR sealing material
• AO/TC design
• double lip construction
• spring-loaded primary sealing lip
• additional dust lip
• compatibility with the specific medium
• requirements of the specific installation

Matching only the inside and outside diameters is not sufficient.

The complete 100x125x13 mm dimensions, sealing material and lip configuration should correspond to the requirements of the installation.

FAQ

What are the dimensions of the GRN 100x125x13 oil seal?

The seal has a 100 mm inside diameter, 125 mm outside diameter and 13 mm width. Its nominal dimensions are 100x125x13 mm.

What does AO/TC mean for the 100x125x13 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 GRN 100x125x13 NBR AO/TC a double lip oil seal?

Yes. GRN 100x125x13 NBR AO/TC is a double lip radial shaft oil seal.

Does the 100x125x13 oil seal have a garter spring?

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

Does the AO/TC design have an additional dust lip?

Yes. The AO/TC construction incorporates an additional dust lip that helps restrict external contaminants from reaching the primary sealing area.

What material is the 100x125x13 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 a 100x125x13 and 100x125x14 oil seal?

Both have a nominal 100 mm inside diameter and 125 mm outside diameter. The difference is the width: 100x125x13 is 13 mm wide, while 100x125x14 is 14 mm wide.

What is the difference between a 100x125x13 and 100x125x12 oil seal?

Is a 100x125x13 oil seal interchangeable with a 100x125x14 seal?

Not automatically. The two sizes differ by 1 mm in width. The seal housing, original component dimensions and required sealing specification should be verified before substitution.

Can any 100x125x13 oil seal replace this GRN AO/TC version?

Not necessarily. Matching the 100x125x13 mm dimensions alone does not confirm interchangeability. A replacement should also match the required NBR material, AO/TC double lip construction, spring-loaded primary sealing lip and additional dust lip.

Can a single lip 100x125x13 oil seal replace this AO/TC version?

Not automatically. A single lip version does not incorporate the additional dust lip present in this AO/TC design. The required sealing construction should be verified for the specific installation.
