100x120x10 Oil Seal Dimensions

The principal dimensions are:

d - Inside diameter / shaft diameter: 100 mm

D - Outside diameter: 120 mm

B - Width: 10 mm

Dimensions: 100x120x10 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.

VMQ/MVQ Silicone Sealing Material

The sealing material of this oil seal is:

VMQ/MVQ - silicone rubber

The silicone material is one of the principal identifying characteristics of this particular 100x120x10 mm oil seal.

This distinction is important because oil seals with the same nominal dimensions are also available in other elastomer materials, including NBR.

The sealing material should therefore be verified together with the dimensions and lip design when selecting a replacement.

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.

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 100x120x10 VMQ/MVQ 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 the product with other 100x120x10 mm radial shaft oil seals.

Matching dimensions alone do not establish identical sealing construction.

Silicone 100x120x10 VMQ/MVQ vs NBR Oil Seal

Oil seals with the same 100x120x10 mm dimensions are available in different sealing materials.

The key material distinction is:

100x120x10 VMQ/MVQ - silicone rubber

100x120x10 NBR - Nitrile Butadiene Rubber

The two versions can therefore have identical nominal dimensions while using different elastomer materials.

They should not be treated as identical products based only on the 100x120x10 mm dimensions.

The required sealing material should correspond to the medium and operating conditions of the specific installation.

100x120x10 VMQ/MVQ AO/TC vs NBR AO/TC

A silicone VMQ/MVQ version and an NBR version may share the same:

100 mm shaft diameter

120 mm outside diameter

10 mm width

AO/TC double lip construction

The principal difference is the sealing material.

GRN 100x120x10 VMQ/MVQ AO/TC - silicone rubber

GRN 100x120x10 NBR AO/TC - NBR

They are therefore separate material variants of a 100x120x10 radial shaft oil seal.

What Does 100x120x10 Mean?

The designation 100x120x10 defines the three principal dimensions of the radial shaft seal:

100 mm - nominal shaft diameter

120 mm - nominal outside diameter

10 mm - seal width

All three values are important for correct product identification.

An oil seal should not be selected solely by its shaft diameter or outside diameter.

How to Select a 100x120x10 Silicone Oil Seal

When selecting a replacement, verify:

• 100 mm shaft diameter
• 120 mm outside diameter
• 10 mm width
• VMQ/MVQ silicone sealing material
• AO/TC design
• double lip construction
• spring-loaded primary sealing lip
• additional dust lip
• compatibility of the sealing material with the medium
• requirements of the specific installation

Matching the 100x120x10 mm dimensions alone does not confirm full interchangeability.

The sealing material and lip configuration should also correspond to the requirements of the installation.

FAQ

What are the dimensions of the GRN 100x120x10 silicone oil seal?

The seal has a 100 mm inside diameter, 120 mm outside diameter and 10 mm width. Its nominal dimensions are 100x120x10 mm.

What material is the 100x120x10 oil seal made from?

This version is manufactured from VMQ/MVQ silicone rubber.

What does VMQ mean on an oil seal?

VMQ is a technical designation used for silicone rubber elastomers. The product may also be encountered under the MVQ designation in commercial catalogs.

Is GRN 100x120x10 MVQ a silicone oil seal?

Yes. This version of the GRN 100x120x10 oil seal uses silicone rubber as its sealing material.

What does AO/TC mean for the 100x120x10 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 100x120x10 VMQ/MVQ AO/TC a double lip oil seal?

Yes. GRN 100x120x10 VMQ/MVQ AO/TC is a double lip radial shaft oil seal.

Does the 100x120x10 silicone 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 a dust lip?

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

What is the difference between 100x120x10 VMQ/MVQ and 100x120x10 NBR?

The principal difference is the sealing material. The VMQ/MVQ version uses silicone rubber, while the NBR version uses Nitrile Butadiene Rubber. Matching dimensions do not make the two material versions identical.

Are 100x120x10 VMQ/MVQ and 100x120x10 NBR the same oil seal?

No. They may have identical nominal dimensions, but they use different elastomer materials. They should be treated as separate material variants.

Can a 100x120x10 NBR oil seal replace this silicone version?

Not automatically. Matching dimensions and lip configuration do not establish material compatibility. The replacement material should be suitable for the medium and operating conditions of the specific installation.

Can any 100x120x10 oil seal replace this GRN silicone AO/TC version?

Not necessarily. Matching the 100x120x10 mm dimensions alone does not confirm interchangeability. A replacement should also match the required sealing material, AO/TC double lip construction, spring-loaded primary sealing lip and additional dust lip.
