GRN -> 35x56x12 mm -> NBR -> AO/TC -> double lip radial shaft oil seal

35x56x12 Oil Seal Dimensions

The principal dimensions are:

d - Inside diameter / shaft diameter: 35 mm

D - Outside diameter: 56 mm

B - Width: 12 mm

Dimensions: 35x56x12 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 35x56x12 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 the product with other 35x56x12 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.

35x56x12 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.

Oil seals with identical 35x56x12 mm dimensions can therefore differ in their sealing lip configuration.

What Does 35x56x12 Mean?

The designation 35x56x12 defines the three principal dimensions of the radial shaft seal:

35 mm - nominal shaft diameter

56 mm - nominal outside diameter

12 mm - seal width

All three values are important for correct product identification.

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

How to Select a 35x56x12 Oil Seal

When selecting a replacement, verify:

• 35 mm shaft diameter
• 56 mm outside diameter
• 12 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 the 35x56x12 mm dimensions alone does not confirm full interchangeability.

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

FAQ

What are the dimensions of the GRN 35x56x12 oil seal?

The seal has a 35 mm inside diameter, 56 mm outside diameter and 12 mm width. Its nominal dimensions are 35x56x12 mm.

What does 35x56x12 mean on an oil seal?

It means the seal has a 35 mm nominal shaft diameter, 56 mm outside diameter and 12 mm width.

What does AO/TC mean for the 35x56x12 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 35x56x12 NBR AO/TC a double lip oil seal?

Yes. GRN 35x56x12 NBR AO/TC is a double lip radial shaft oil seal.

Does the 35x56x12 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 GRN 35x56x12 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.
