GRN® 110x130x15 NBR AO/TC Double Lip Rotary Shaft Seal

GRN® 110x130x15 NBR AO/TC Double Lip Rotary Shaft Seal

GRN® 110x130x15 NBR AO/TC is a double lip radial shaft seal / rotary shaft seal with nominal dimensions of 110x130x15 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 main sealing zone.

Complete product identification:

GRN® + 110x130x15 mm + NBR + AO/TC

GRN® 110x130x15 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: 110x130x15 mm

Shaft diameter d: 110 mm

Outside diameter D: 130 mm

Width B: 15 mm

Primary sealing lip: Spring-loaded

Additional lip: Auxiliary dust lip

For precise identification, the complete combination 110x130x15 mm + NBR + AO/TC + GRN® should be retained.

GRN® 110x130x15 Dimensions

The nominal installation dimensions are:

d = 110 mm - nominal shaft diameter

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

B = 15 mm - nominal axial seal width

Complete size:

110x130x15 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 15 mm dimension specifies the axial width of this particular variant.

All three dimensions should be retained during product identification. The designation should not be shortened to 110x130, because the 15 mm width is an integral part of the dimensional specification.

AO/TC Double Lip Seal Design

The AO/TC designation identifies the double lip sealing configuration of this product.

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 function and helps limit external contamination from reaching the main sealing area.

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® 110x130x15 AO/TC Works

GRN® 110x130x15 NBR AO/TC is a radial shaft sealing element that creates 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 located on the external side of the primary sealing arrangement and provides an additional barrier against contamination.

This product is a sealing component and 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. It does not by itself define the exact compound formulation or all operating limits of the finished product.

Without product-specific manufacturer documentation for the exact GRN® 110x130x15 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 parameters for this exact GRN® variant.

Meaning of 110x130x15 NBR AO/TC

The product designation can be interpreted as follows:

110 - nominal shaft diameter in mm

130 - nominal outside diameter in mm

15 - nominal axial width in mm

NBR - Nitrile Butadiene Rubber

AO/TC - double lip sealing configuration

GRN® - product brand

The complete identification is therefore:

GRN® + 110x130x15 + NBR + AO/TC

Dimensions should not be considered independently from the material and sealing configuration when selecting a technical replacement.

Selection and Interchangeability

When selecting a replacement for GRN® 110x130x15 NBR AO/TC, verify at least:

• d = 110 mm
• D = 130 mm
• B = 15 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 110x130x15 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.

GRN® 110x130x15 vs 110x135 and 110x140 Shaft Seals

This variant should be kept separate from GRN® shaft seals with 135 mm or 140 mm outside diameters.

For this product:

d = 110 mm

D = 130 mm

B = 15 mm

A 110x135x12 seal has an outside diameter of 135 mm.

A 110x140x13 or 110x140x14 seal has an outside diameter of 140 mm.

Although these products share the same nominal 110 mm shaft diameter, they require different nominal housing bore diameters and are not dimensionally identical.

Technical Specification

FAQ

What are the dimensions of GRN® 110x130x15 NBR AO/TC?

The nominal dimensions are 110x130x15 mm: shaft diameter d = 110 mm, outside diameter D = 130 mm and axial width B = 15 mm.

What type of seal is GRN® 110x130x15 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® 110x130x15 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® 110x130x15 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 function 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.

Is another 110x130x15 oil seal automatically interchangeable?

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

Can a 110x135 or 110x140 seal replace GRN® 110x130x15?

No direct dimensional interchangeability should be assumed. This product has D = 130 mm, whereas 110x135 and 110x140 seals have outside diameters of 135 mm and 140 mm respectively and therefore require different nominal housing bore diameters.
