GRN® 95x115x13 NBR AO - Technical Characteristics

The principal identification parameters are:

Brand: GRN®

Product type: Radial shaft seal / rotary shaft seal / oil seal

Design: AO

Configuration: Double lip

Material: NBR

Material name: Nitrile Butadiene Rubber

Dimensions: 95x115x13 mm

Shaft diameter d: 95 mm

Outside diameter D: 115 mm

Width B: 13 mm

The most precise product identification is:

GRN® + 95x115x13 + NBR + AO

GRN® 95x115x13 Dimensions

The nominal installation dimensions are:

d: 95 mm - nominal shaft diameter

D: 115 mm - nominal seal outside diameter

B: 13 mm - nominal axial width

Complete size:

95x115x13 mm

The first dimension, 95 mm, identifies the nominal shaft diameter.

The second dimension, 115 mm, identifies the nominal outside diameter of the seal and corresponding housing bore dimension.

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

All three dimensions should be retained when searching for the product or evaluating a technical replacement.

AO Double Lip Seal Design

The exact design designation of this product is:

AO

The product is identified as a double lip radial shaft seal.

The AO designation should be retained in the product title, description and technical specification because it forms part of the exact product identity.

It should not automatically be changed from:

AO

to:

AO/TC

These are different design notations. Without manufacturer-specific documentation confirming full equivalence, they should not be treated as identical profile designations.

Likewise, detailed lip geometry associated with a TC profile should not automatically be assigned to this AO product merely because both products may be described as double lip shaft seals.

How Does a Radial Shaft Seal Work?

A radial shaft seal operates at the interface between a rotating shaft and a stationary housing.

For this variant:

Shaft diameter d: 95 mm

Outside diameter D: 115 mm

Width B: 13 mm

The sealing element operates against the rotating shaft surface, creating a dynamic sealing interface where the shaft passes through the housing.

For the exact GRN® 95x115x13 NBR AO variant, its double lip AO design is an important product-specific identification characteristic.

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

NBR - Nitrile Butadiene Rubber

The specified sealing material is:

NBR - Nitrile Butadiene Rubber

NBR is a widely used elastomer family in sealing technology.

For GRN® 95x115x13 NBR AO, the NBR designation forms an integral part of the exact product specification.

However, the NBR designation alone does not identify the exact elastomer compound used for this seal.

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

Shore A hardness

Minimum operating temperature

Maximum operating temperature

Maximum rotational speed

Maximum shaft surface speed

Maximum operating pressure

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

What Does 95x115x13 NBR AO Mean?

The designation can be interpreted as follows:

95 - nominal shaft diameter in mm

115 - nominal outside diameter in mm

13 - nominal axial width in mm

NBR - Nitrile Butadiene Rubber

AO - seal design designation

GRN® - product brand

Complete identification:

GRN® + 95x115x13 + NBR + AO

Each element should be retained when identifying the exact product.

GRN® 95x115x13 AO vs 95x120x13 AO

These two products share the same nominal shaft diameter, width, material and AO design designation.

However, their outside diameters are different.

The key difference is:

95x115x13 - D: 115 mm

95x120x13 - D: 120 mm

The nominal outside diameter differs by 5 mm.

These variants therefore require different nominal housing bore dimensions and should not be treated as direct replacements.

GRN® 95x115x13 vs 95x120x12

The 95x115x13 variant should also be distinguished from 95x120x12.

95x115x13 AO

d: 95 mm

D: 115 mm

B: 13 mm

95x120x12 AO

d: 95 mm

D: 120 mm

B: 12 mm

The products differ in both outside diameter and axial width.

Sharing the same nominal 95 mm shaft diameter does not establish interchangeability.

Selection and Interchangeability

When selecting a replacement for GRN® 95x115x13 NBR AO, verify at least:

• Shaft diameter d: 95 mm
• Outside diameter D: 115 mm
• Width B: 13 mm
• Material: NBR
• Design: AO
• Configuration: Double lip

Matching the nominal 95 mm shaft diameter alone is not sufficient.

Particular attention should be paid to 95x120x13 seals because they share the same shaft diameter and width but have an outside diameter that is 5 mm larger.

When evaluating a replacement from another manufacturer, the seal design, elastomer material and requirements of the specific application should also be verified.

Technical Specification

FAQ

What are the dimensions of GRN® 95x115x13 NBR AO?

The nominal dimensions are 95x115x13 mm, with a 95 mm shaft diameter, 115 mm outside diameter and 13 mm axial width.

What material is GRN® 95x115x13 AO made from?

The specified sealing material is NBR - Nitrile Butadiene Rubber.

Is GRN® 95x115x13 AO a double lip seal?

Yes. This variant is identified as a double lip radial shaft seal.

What does AO mean?

AO is the design designation of this shaft seal variant and should be retained when identifying or selecting the product.

Are AO and AO/TC the same design?

This should not be assumed. The exact designation of this product is AO, and it should not automatically be replaced with AO/TC.

What is the difference between 95x115x13 and 95x120x13?

Both variants have a 95 mm shaft diameter and 13 mm width. Their outside diameters differ: 115 mm and 120 mm.

Can a 95x120x13 seal replace a 95x115x13 seal?

No. The nominal outside diameter differs by 5 mm, so the two seals require different housing bore dimensions.

Is every 95x115x13 NBR seal interchangeable with GRN® AO?

No. In addition to the dimensions and NBR material, the seal design and requirements of the specific application should also be verified.
