GRN® 95x120x13 NBR AO is a double lip radial shaft seal / rotary shaft seal with nominal dimensions of 95x120x13 mm, manufactured from NBR - Nitrile Butadiene Rubber. The exact design designation of this variant is AO.

The principal dimensions are d: 95 mm, D: 120 mm and B: 13 mm. The dimensions, NBR material and AO design should be considered together when identifying the product or selecting a replacement.

Complete identification:

GRN® + 95x120x13 mm + NBR + AO

GRN® 95x120x13 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: 95x120x13 mm

Shaft diameter d: 95 mm

Outside diameter D: 120 mm

Width B: 13 mm

The most precise product identification is:

GRN® + 95x120x13 + NBR + AO

GRN® 95x120x13 Dimensions

The nominal dimensions are:

d: 95 mm - nominal shaft diameter

D: 120 mm - nominal seal outside diameter

B: 13 mm - nominal axial width

Complete size:

95x120x13 mm

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

The second dimension, 120 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, and without manufacturer-specific documentation they should not be treated as identical technical designations.

Likewise, detailed construction characteristics associated with a TC profile should not automatically be assigned to this AO product merely because both products may be described as double lip 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 product, the nominal shaft diameter is 95 mm, while the nominal outside diameter is 120 mm.

The sealing element operates against the shaft surface, creating the dynamic sealing interface.

For this exact variant, the important product-specific identification is its double lip AO design.

Without detailed manufacturer documentation for this exact GRN® variant, more specific functions or geometry should not be assigned to the individual lips as confirmed product characteristics.

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® 95x120x13 NBR AO, the material designation forms an integral part of the exact product specification.

However, the NBR designation alone does not establish the exact elastomer compound used in this product.

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

Shore A hardness

Minimum operating temperature

Maximum operating temperature

Maximum shaft speed

Maximum shaft surface speed

Maximum operating pressure

These parameters depend on the specific elastomer compound, seal construction and operating conditions.

What Does 95x120x13 NBR AO Mean?

The designation can be interpreted as follows:

95 - nominal shaft diameter in mm

120 - 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® + 95x120x13 + NBR + AO

Each element should be retained when identifying the exact product.

GRN® 95x120x13 AO vs 95x140x13 AO/TC

This product should be clearly distinguished from:

GRN® 95x140x13 NBR AO/TC

The main differences are:

Both variants share the same nominal shaft diameter and axial width, but the outside diameter differs by 20 mm and the design designation is different.

They are therefore separate technical variants.

GRN® 95x120x13 AO vs CORTECO 95x140x13 ACM B1SL

This product should also be distinguished from CORTECO 12001465B 95x140x13 ACM B1SL.

The CORTECO variant has:

d: 95 mm

D: 140 mm

B: 13 mm

Material: ACM

Design: B1SL

This GRN® variant has:

d: 95 mm

D: 120 mm

B: 13 mm

Material: NBR

Design: AO

The products therefore differ in outside diameter, sealing material and design.

They should not be treated as equivalent products merely because they share the same 95 mm nominal shaft diameter.

Selection and Interchangeability

When selecting a replacement for GRN® 95x120x13 NBR AO, verify at least:

• Shaft diameter d: 95 mm
• Outside diameter D: 120 mm
• Width B: 13 mm
• Material: NBR
• Design: AO
• Configuration: Double lip

Matching the shaft diameter alone is not sufficient.

For example, a 95x140x13 seal cannot be considered a dimensional replacement for 95x120x13 simply because both are designed for a nominal 95 mm shaft.

Their outside diameters differ by 20 mm.

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

Technical Specification

FAQ

What are the dimensions of GRN® 95x120x13 NBR AO?

The nominal dimensions are 95x120x13 mm, with a 95 mm shaft diameter, 120 mm outside diameter and 13 mm axial width.

What material is GRN® 95x120x13 AO made from?

The specified sealing material is NBR - Nitrile Butadiene Rubber.

Is GRN® 95x120x13 AO a double lip seal?

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

Are AO and AO/TC exactly the same design?

This should not be assumed. The exact designation of this product is AO, and this designation should be retained when identifying or selecting the product.

What does 95 mean in 95x120x13?

The first dimension identifies the nominal 95 mm shaft diameter.

What does 120 mean in 95x120x13?

The second dimension identifies the nominal 120 mm outside diameter of the shaft seal.

Can a 95x140x13 seal replace a 95x120x13 seal?

No. Their outside diameters differ by 20 mm, so they represent different installation dimensions.

Is every 95x120x13 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 be verified.
