95x130x13 NBR AO GRN Double Lip Radial Shaft Oil Seal

95x130x13 NBR AO GRN Double Lip Radial Shaft Oil Seal

95x130x13 NBR AO GRN® is a double-lip radial shaft oil seal designed for a 95 mm shaft and 130 mm housing bore, with a width of 13 mm.

The AO design combines a spring-loaded primary sealing lip with an additional dust lip. The primary lip provides the main sealing function against the rotating shaft, while the second lip helps protect the sealing area against external contamination.

What Does 95x130x13 Mean?

The designation 95x130x13 mm defines the three principal installation dimensions:

95 mm - nominal shaft diameter
130 mm - nominal housing bore diameter
13 mm - seal width

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

The material and sealing lip configuration should also match the requirements of the application.

AO Double-Lip Design

The AO design uses two lips with different functions.

The primary sealing lip operates directly against the rotating shaft and provides the main dynamic sealing function.

It is supported by a garter spring that helps maintain contact between the elastomer sealing edge and shaft surface.

The additional dust lip provides a secondary barrier on the external side of the seal and helps protect the primary sealing area against contamination.

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 lip and rotating shaft surface.

The principal dynamic sealing interface therefore consists of:

primary sealing lip + garter spring + shaft counterface

The condition of the shaft surface and correct installation are therefore important factors in sealing performance.

Additional Dust Lip

The second lip of the AO design performs a protective function.

It helps reduce the entry of:

dust,
dirt,
small particles,
external contamination

into the primary sealing area.

This additional protective barrier is the principal functional difference between the AO double-lip design and a corresponding single-lip radial shaft seal.

NBR Nitrile Rubber

The seal is manufactured from NBR - Nitrile Butadiene Rubber.

NBR is one of the most widely used elastomers for radial shaft oil seals and provides good compatibility with many:

mineral oils,
lubricating greases,
industrial lubricants.

Material compatibility should always be verified against the specific medium, additives, temperature and actual operating conditions.

NBR should not be considered universally resistant to every oil, chemical or fluid.

95x130x13 AO vs Single-Lip Oil Seal

Two radial shaft seals can have identical 95x130x13 mm dimensions but different sealing configurations.

AO double lip: spring-loaded primary sealing lip + additional dust lip

Single-lip design: primary sealing lip without the additional dust lip

For this reason, dimensions alone should not be used to determine full interchangeability.

If the original application requires an AO design, a single-lip seal should not automatically be considered an equivalent replacement.

What Is a 95x130x13 Oil Seal Used For?

A radial shaft oil seal operates between a rotating shaft and stationary housing.

Its principal functions are to:

retain oil or grease on the required side of the seal,
reduce lubricant leakage along the rotating shaft,
help protect the primary sealing area against external contamination.

Actual suitability depends on the operating medium, temperature, shaft speed, pressure, shaft surface condition and installation geometry.

Check the Shaft Counterface

The primary sealing lip operates directly against the shaft surface.

Before installing a new 95x130x13 radial shaft oil seal, inspect the sealing track for:

wear grooves,
scratches,
corrosion,
mechanical damage,
surface contamination.

A new oil seal installed on a worn or damaged shaft surface may still leak because the primary sealing lip requires a suitable counterface to operate correctly.

How to Select GRN 95x130x13 NBR AO

Complete product identification:

GRN® -> 95x130x13 mm -> NBR -> AO -> Double Lip

Verify:

Shaft diameter: 95 mm
Housing bore diameter: 130 mm
Width: 13 mm
Material: NBR
Design: AO
Configuration: Double lip

Matching 95x130x13 mm dimensions alone does not guarantee full interchangeability.

Radial shaft seals with identical dimensions can differ in elastomer material and sealing lip configuration.

FAQ

What are the dimensions of the GRN 95x130x13 oil seal?

The seal is designed for a 95 mm shaft and 130 mm housing bore, with a width of 13 mm.

Is 95x130x13 NBR AO a double-lip oil seal?

Yes. The AO design combines a primary sealing lip with an additional dust lip.

Does the 95x130x13 AO oil seal have a spring?

Yes. The primary sealing lip is supported by a garter spring that helps maintain sealing contact with the shaft.

What material is the seal made from?

The seal is manufactured from NBR - Nitrile Butadiene Rubber.

Is NBR suitable for oil?

NBR is widely used with many mineral oils and lubricating greases. Compatibility should always be verified for the specific medium and operating conditions.

What is the purpose of the additional lip?

The additional lip helps protect the primary sealing area against dust, dirt and other external contaminants.

Can a single-lip 95x130x13 seal replace an AO seal?

Not automatically. The AO design includes an additional dust lip, so the required sealing configuration should be verified before replacement.

Are all 95x130x13 oil seals interchangeable?

No. Seals with identical dimensions can differ in material, sealing lip configuration and design.
