What Does 80x100x13 Mean?

The designation 80x100x13 mm identifies the three principal installation dimensions:

80 mm - nominal shaft diameter

100 mm - nominal housing bore diameter

13 mm - seal width

All three dimensions should be verified when selecting a replacement radial shaft oil seal.

Matching the shaft diameter alone is not sufficient.

AO/BASL Double-Lip Design

The GRN® oil seal uses the:

AO/BASL

design.

For this product, AO/BASL identifies a double-lip configuration consisting of a primary dynamic sealing lip and an additional dust lip.

The primary lip operates against the rotating shaft and performs the main sealing function.

The secondary lip is positioned toward the external side of the seal and helps restrict contaminants from reaching the primary sealing area.

Spring-Loaded Primary Sealing Lip

The primary sealing lip is supported by a:

garter spring

The spring helps maintain radial contact between the elastomer sealing edge and the shaft counterface.

The condition of the shaft surface in the sealing zone is therefore an important installation parameter.

Wear grooves, corrosion or surface damage in the lip contact area can affect sealing performance even when a new oil seal is installed.

Additional Dust Lip

The AO/BASL construction incorporates an:

additional dust lip

Its function is to help restrict dust, dirt and other external contaminants from reaching the primary dynamic sealing interface.

This secondary lip is an important distinction between this AO/BASL product and a basic single-lip radial shaft oil seal.

When comparing alternatives, the lip configuration should therefore be checked together with the dimensions and material.

NBR Nitrile Butadiene Rubber

The sealing material is:

NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers for radial shaft oil seals.

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

Actual compatibility depends on the lubricant formulation, additives, temperature and operating conditions.

A fixed maximum temperature, pressure or shaft speed should not be assigned without technical data for the exact NBR compound and application.

AO/BASL vs Single-Lip Oil Seal

The principal difference is the lip configuration.

GRN® 80x100x13 NBR AO/BASL:

primary sealing lip

garter spring

additional dust lip

A basic single-lip radial shaft oil seal does not incorporate the additional external dust lip.

Therefore, two seals with identical 80x100x13 mm dimensions are not necessarily equivalent.

80x100x13 NBR vs FPM/FKM Oil Seal

Radial shaft oil seals measuring 80x100x13 mm can be manufactured from different elastomers.

This GRN® version is manufactured from:

NBR

It should not automatically be considered material-equivalent to:

80x100x13 FPM/FKM

NBR and FPM/FKM are different elastomer families with different resistance profiles.

The sealing material should be selected according to the lubricant, temperature and operating environment of the application.

Is Every 80x100x13 Oil Seal the Same?

No.

Identical nominal dimensions do not establish complete interchangeability.

Oil seals measuring 80x100x13 mm can differ in:

elastomer material

lip configuration

presence of a dust lip

outer diameter construction

sealing lip geometry

directional or non-directional design

The complete identification of this product is therefore:

GRN® 80x100x13 NBR AO/BASL

rather than simply:

80x100x13 oil seal

How to Select 80x100x13 NBR AO/BASL GRN®

Verify the following parameters:

Shaft Diameter: 80 mm
Housing Bore Diameter: 100 mm
Width: 13 mm
Material: NBR
Design: AO/BASL
Configuration: Double lip
Primary Lip: Spring-loaded
Dust Lip: Yes

If the original seal has additional characteristics such as directional hydrodynamic geometry or a special elastomer compound, these must also be considered.

Dimensions alone do not confirm full interchangeability.

FAQ

What are the dimensions of the GRN® 80x100x13 NBR AO/BASL oil seal?

The seal has an 80 mm shaft diameter, 100 mm housing bore diameter and 13 mm width.

What does AO/BASL mean?

For this GRN® product, AO/BASL identifies a double-lip radial shaft oil seal design with a primary sealing lip and an additional dust lip.

Does the 80x100x13 AO/BASL oil seal have a spring?

Yes. The primary sealing lip is supported by a garter spring.

Does the AO/BASL 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 this 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.

Can a standard 80x100x13 oil seal replace AO/BASL?

Interchangeability should not be assumed from dimensions alone. The NBR material, double-lip configuration, dust lip and any other application-specific requirements should also be verified.

What is the EAN for the GRN® 80x100x13 NBR AO/BASL oil seal?

The EAN is 5903641608138.
