GRN® 110x130x10 NBR AO/TC Double Lip Rotary Shaft Seal

GRN® 110x130x10 NBR AO/TC Double Lip Rotary Shaft Seal

GRN® 110x130x10 NBR AO/TC is a double lip radial shaft seal / rotary shaft seal with nominal dimensions of 110x130x10 mm. It is manufactured from NBR - Nitrile Butadiene Rubber and uses the AO/TC double lip configuration. The primary dynamic sealing lip is spring-loaded, while the additional auxiliary lip provides a protective barrier on the external side of the primary sealing zone.

A key dimensional feature of this variant is its B = 10 mm width, distinguishing it from other GRN® 110x130 seals with different axial widths.

GRN® 110x130x10 NBR AO/TC - Technical Characteristics

The principal identification parameters are:

Brand: GRN®

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

Design: AO/TC

Configuration: Double lip

Material: NBR

Material name: Nitrile Butadiene Rubber

Dimensions: 110x130x10 mm

Shaft diameter d: 110 mm

Outside diameter D: 130 mm

Width B: 10 mm

Primary sealing lip: Spring-loaded

Additional lip: Auxiliary dust lip

For precise identification, the complete combination 110x130x10 mm + NBR + AO/TC + GRN® should be retained.

GRN® 110x130x10 Dimensions

The nominal installation dimensions are:

d = 110 mm - nominal shaft diameter

D = 130 mm - nominal seal outside diameter / corresponding housing bore diameter

B = 10 mm - nominal axial seal width

Complete size:

110x130x10 mm

The 110 mm dimension corresponds to the nominal shaft diameter on which the primary dynamic sealing lip operates.

The 130 mm dimension defines the nominal outside diameter of the seal and the corresponding nominal housing bore.

The 10 mm dimension specifies the axial width of this exact variant.

All three dimensions should be retained during product identification. The designation should not be shortened to 110x130, because seals with the same shaft and outside diameters may have different widths.

AO/TC Double Lip Seal Design

The AO/TC designation identifies a double lip sealing configuration.

The construction comprises:

Primary sealing lip - operates dynamically against the rotating shaft.

Garter spring - provides radial loading of the primary sealing edge against 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 has a separate protective role and helps limit external contamination from reaching the primary sealing zone.

For this reason, an AO/TC double lip seal should not automatically be replaced by a single-lip seal, even when the nominal installation dimensions are identical.

How GRN® 110x130x10 AO/TC Works

GRN® 110x130x10 NBR AO/TC is a radial shaft sealing element designed to create a sealing interface between a rotating shaft and a stationary housing.

The seal is installed in a housing corresponding to its nominal D = 130 mm outside diameter.

The primary sealing lip operates dynamically against a shaft with a nominal diameter of d = 110 mm. The garter spring assists in maintaining radial contact between the sealing edge and the shaft surface.

The additional auxiliary lip is positioned on the external side of the primary sealing arrangement and provides an additional barrier against contamination.

This product is a sealing component. It does not carry radial or axial loads in the manner of a rolling bearing.

NBR - Nitrile Butadiene Rubber

The specified sealing material is:

NBR - Nitrile Butadiene Rubber

NBR identifies the elastomer family used for this seal. The NBR designation alone does not define the exact compound formulation or all operating limits of the finished product.

Without product-specific manufacturer documentation for the exact GRN® 110x130x10 NBR AO/TC, no specific value should be assigned for:

Shore A hardness,

minimum or maximum operating temperature,

maximum rotational speed,

maximum shaft surface speed,

maximum permissible pressure.

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

Meaning of 110x130x10 NBR AO/TC

The designation can be interpreted as follows:

110 - nominal shaft diameter in mm

130 - nominal outside diameter in mm

10 - nominal axial width in mm

NBR - Nitrile Butadiene Rubber

AO/TC - double lip sealing configuration

GRN® - product brand

Complete identification:

GRN® + 110x130x10 + NBR + AO/TC

The third dimension should not be omitted. The 10 mm width is an important identification parameter distinguishing this seal from other 110x130 variants.

GRN® 110x130x10 vs 110x130x15

The 110x130x10 and 110x130x15 variants share the same nominal diameters:

d = 110 mm

D = 130 mm

However, their axial widths are different:

110x130x10 - B = 10 mm

110x130x15 - B = 15 mm

The difference in axial width is 5 mm.

These products should therefore be treated as separate dimensional variants and should not automatically be considered interchangeable.

The required seal width and the geometry of the actual installation should be verified before replacement.

Keeping separate product pages for 110x130x10 and 110x130x15 also provides clearer technical identification and prevents the two dimensional variants from being incorrectly treated as the same product.

Selection and Interchangeability

When selecting a replacement for GRN® 110x130x10 NBR AO/TC, verify at least:

• d = 110 mm
• D = 130 mm
• B = 10 mm
• NBR material
• AO/TC double lip configuration
• spring-loaded primary sealing lip
• additional 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.

Identical 110x130x10 mm dimensions do not automatically establish full technical interchangeability.

A seal from another manufacturer may have the same nominal dimensions but a different elastomer compound, lip geometry or operating limits.

Technical Specification

FAQ

What are the dimensions of GRN® 110x130x10 NBR AO/TC?

The nominal dimensions are 110x130x10 mm: shaft diameter d = 110 mm, outside diameter D = 130 mm and axial width B = 10 mm.

What type of seal is GRN® 110x130x10 AO/TC?

It is a double lip radial shaft seal, also described in English 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® 110x130x10 AO/TC made from?

The specified elastomer is NBR - Nitrile Butadiene Rubber. The exact compound formulation and hardness should not be assumed without product-specific manufacturer data.

Does GRN® 110x130x10 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 is the purpose of the additional lip?

The auxiliary lip provides an additional protective barrier on the external side of the primary sealing arrangement and helps limit contamination from reaching the main sealing zone.

What is the difference between 110x130x10 and 110x130x15?

Both variants have d = 110 mm and D = 130 mm, but their widths differ. The 110x130x10 variant has B = 10 mm, while the 110x130x15 variant has B = 15 mm.

Is another 110x130x10 oil seal automatically interchangeable with GRN® AO/TC?

No. Matching dimensions alone do not establish complete technical interchangeability. The material, lip configuration and relevant operating conditions should also be compared.
