GRN® 95x140x13 NBR AO/TC Double Lip Rotary Shaft Seal

GRN® 95x140x13 NBR AO/TC Double Lip Rotary Shaft Seal

GRN® 95x140x13 NBR AO/TC is a double lip radial shaft seal / rotary shaft seal with nominal dimensions of 95x140x13 mm, manufactured from NBR - Nitrile Butadiene Rubber. The AO/TC configuration combines a spring-loaded primary sealing lip with an additional auxiliary dust lip.

The principal dimensions of this exact variant are d: 95 mm, D: 140 mm and B: 13 mm. All three dimensions, the NBR material and the AO/TC configuration should be retained when identifying the product and selecting a replacement.

GRN® 95x140x13 Shaft Seal Dimensions

The nominal installation dimensions are:

d: 95 mm - nominal shaft diameter

D: 140 mm - nominal seal outside diameter / corresponding housing bore diameter

B: 13 mm - nominal axial seal width

Complete size:

95x140x13 mm

The first dimension, 95 mm, corresponds to the nominal shaft diameter on which the primary dynamic sealing lip operates.

The second dimension, 140 mm, defines the nominal outside diameter of the seal and the corresponding nominal housing bore.

The third dimension, 13 mm, specifies the nominal axial width.

All three dimensions form part of the exact dimensional identification.

AO/TC Double Lip Seal Design

The AO/TC designation identifies a double lip radial shaft seal configuration.

The construction comprises:

Primary sealing lip - operates dynamically against the rotating shaft.

Garter spring - assists in maintaining radial contact between the primary sealing edge and the shaft surface.

Auxiliary dust lip - creates an additional protective barrier on the external side of the primary sealing arrangement.

The spring-loaded primary lip performs the principal dynamic sealing function.

The auxiliary lip helps limit external contamination from reaching the primary sealing zone.

Profile terminology can vary between manufacturers. Therefore, the AO/TC designation should not automatically be treated as technically identical to every double lip shaft seal profile used by another manufacturer.

How GRN® 95x140x13 AO/TC Works

A radial shaft seal creates a dynamic sealing interface between a rotating shaft and a stationary housing.

For this variant:

Shaft diameter d: 95 mm

Outside diameter D: 140 mm

Width B: 13 mm

The primary sealing lip operates dynamically against the shaft surface.

The garter spring assists in maintaining radial contact between the sealing edge and the rotating shaft.

The additional auxiliary dust lip creates an extra protective barrier on the external side of the primary sealing arrangement.

The seal performs a sealing function and does not replace a bearing or another component responsible for supporting and guiding the shaft.

NBR - Nitrile Butadiene Rubber

The specified sealing material is:

NBR - Nitrile Butadiene Rubber

NBR identifies the elastomer family used for this shaft seal.

For the exact GRN® 95x140x13 NBR AO/TC product, the NBR designation alone does not identify the specific elastomer compound or its complete operating limits.

Without product-specific documentation for this exact variant, no specific value should be assigned for:

Shore A hardness

Minimum operating temperature

Maximum operating temperature

Maximum rotational speed

Maximum shaft surface speed

Maximum permissible pressure

Generic specifications published for NBR shaft seals from other manufacturers should not be presented as confirmed technical parameters for this exact GRN® product.

Meaning of 95x140x13 NBR AO/TC

The product designation can be interpreted as follows:

95 - nominal shaft diameter in mm

140 - nominal outside diameter in mm

13 - nominal axial width in mm

NBR - Nitrile Butadiene Rubber

AO/TC - double lip sealing configuration

GRN® - product brand

Complete identification:

GRN® + 95x140x13 + NBR + AO/TC

Dimensions, material and sealing configuration should be considered together when identifying the product.

Why the Exact 95x140x13 Size Matters

All three dimensions are important when selecting a radial shaft seal.

For this variant:

d: 95 mm

D: 140 mm

B: 13 mm

A 95x140x12 shaft seal has the same nominal shaft diameter and outside diameter but a different axial width.

Likewise, a 95x130x13 shaft seal may share the same shaft diameter and width but has a different outside diameter.

These are separate dimensional variants and should remain separate products in technical catalogues and e-commerce listings.

GRN® 95x140x13 vs 95x140x12

The two variants may share:

Shaft diameter: 95 mm

Outside diameter: 140 mm

Their widths differ:

95x140x13 - B: 13 mm

95x140x12 - B: 12 mm

The difference in nominal axial width is 1 mm.

They are therefore different dimensional variants, and direct interchangeability should not be assumed.

Keeping the exact 95x140x13 and 95x140x12 dimensions in separate product titles also helps search engines and AI systems distinguish between the two products.

Selection and Interchangeability

When selecting a replacement for GRN® 95x140x13 NBR AO/TC, verify at least:

• Brand / identification: GRN®
• Shaft diameter d: 95 mm
• Outside diameter D: 140 mm
• Width B: 13 mm
• Material: NBR
• Design: AO/TC
• Configuration: Double lip
• Primary sealing lip: Spring-loaded
• Additional lip: Auxiliary dust lip

Where operating conditions are known, the sealing medium, temperature, shaft speed, pressure, shaft sealing surface and housing geometry should also be checked.

Matching the nominal 95x140x13 mm dimensions alone does not establish complete technical interchangeability.

A shaft seal from another manufacturer may have identical nominal dimensions but differ in elastomer compound, lip geometry, construction or operating limits.

What type of seal is GRN® 95x140x13?

It is a double lip radial shaft seal, also described as a rotary shaft seal or oil seal.

What does AO/TC mean?

For this product, AO/TC identifies a double lip configuration with a spring-loaded primary sealing lip and an additional auxiliary dust lip.

What material is GRN® 95x140x13 made from?

The specified sealing material is NBR - Nitrile Butadiene Rubber.

Does GRN® 95x140x13 AO/TC have a spring?

Yes. The primary dynamic sealing lip is spring-loaded. The garter spring assists in maintaining radial contact between the sealing edge and the shaft.

What does 95 mean in 95x140x13?

The first dimension identifies the nominal 95 mm shaft diameter.

Can a 95x140x12 seal replace 95x140x13?

Direct interchangeability should not be assumed. Their nominal widths differ by 1 mm, with 13 mm for this product and 12 mm for the other dimensional variant.

Is every 95x140x13 oil seal interchangeable with GRN® AO/TC?

No. In addition to the dimensions, the material, lip configuration, design and relevant operating requirements should also be verified.
