GRN® 90x110x15 NBR TC Double Lip Rotary Shaft Seal

GRN® 90x110x15 NBR TC Double Lip Rotary Shaft Seal

GRN® 90x110x15 NBR TC is a double lip rotary shaft seal with nominal dimensions 90x110x15 mm. The elastomeric sealing element is manufactured from NBR – Nitrile Butadiene Rubber. The TC design incorporates a spring-loaded primary sealing lip and an auxiliary dust lip.

The key product identification is:

GRN® + 90x110x15 + NBR + TC + double lip

The 15 mm width is an essential part of the identification because GRN® shaft seals with the same 90 mm shaft diameter and 110 mm outside diameter are available in other widths.

GRN® 90x110x15 NBR TC – Technical Characteristics

GRN® 90x110x15 Shaft Seal Dimensions

The principal nominal dimensions are:

d: 90 mm – nominal shaft diameter

D: 110 mm – nominal seal outside diameter / housing bore diameter

B: 15 mm – nominal axial width

Complete nominal size:

90x110x15 mm

All three dimensions are important when identifying the correct shaft seal.

The 15 mm width is particularly important because products with the same 90x110 mm diameters are also available with different widths.

TC Double Lip Seal Design

The defining feature of this GRN® variant is its TC double lip construction.

The sealing system incorporates:

a primary sealing lip

supported by:

a garter spring

and:

an auxiliary dust lip.

The primary sealing lip forms the principal dynamic sealing interface with the rotating shaft.

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

The auxiliary dust lip provides an additional protective barrier against external contamination approaching the primary sealing area.

What Does TC Mean?

For this GRN® product, TC identifies a double lip rotary shaft seal design incorporating a spring-loaded primary sealing lip and an auxiliary dust lip.

In the Polish GRN® product nomenclature, the same construction may be identified as:

AO

or:

AO/TC

For the English product catalogue, the preferred designation is:

TC

Therefore:

Polish: GRN® 90x110x15 NBR AO/TC

becomes:

English: GRN® 90x110x15 NBR TC

Profile codes should not automatically be transferred between manufacturers because different brands may use different nomenclature for their seal constructions.

How Does the GRN® 90x110x15 TC Seal Work?

A radial shaft seal operates between a:

rotating shaft

and a:

stationary housing.

For this product, the nominal shaft diameter is:

90 mm

the nominal outside diameter is:

110 mm

and the nominal axial width is:

15 mm.

The primary sealing lip contacts the shaft surface and forms the principal dynamic sealing interface.

The garter spring assists in maintaining the required contact between the sealing lip and shaft.

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

NBR – Nitrile Butadiene Rubber

The elastomeric sealing element is manufactured from:

NBR – Nitrile Butadiene Rubber

NBR is a family of technical elastomers widely used in sealing applications.

The generic NBR designation does not, however, identify the exact compound formulation used in this specific GRN® seal.

Therefore, without documentation for the exact compound, this product should not be assigned an arbitrary:

• Shore A hardness
• minimum operating temperature
• maximum operating temperature
• maximum shaft surface speed
• maximum pressure
• detailed chemical compatibility range

Compatibility should be evaluated according to the actual operating medium and conditions of the application.

GRN® 90x110x15 vs 90x110x10 vs 90x110x8

GRN® shaft seals are available in several variants sharing the same 90 mm shaft diameter and 110 mm outside diameter.

The key difference is the axial width.

These are three distinct dimensional variants.

For SEO and AI Search, they should remain separate product entities:

GRN® 90x110x8 NBR TC

GRN® 90x110x10 NBR TC

GRN® 90x110x15 NBR TC

This makes the exact width clear to users and helps prevent search cannibalization between closely related product pages.

GRN® 90x110x15 vs CORTECO 01030122B 90x110x15.5

A particularly important distinction is between this GRN® seal and:

CORTECO 01030122B 90x110x15.5 FPM

These are different products.

The width differs by 0.5 mm, while the elastomer and profile are also different.

These products should therefore not automatically be treated as interchangeable.

Does TC Specify Rotation Direction?

No.

The TC designation alone does not confirm a directional hydrodynamic sealing geometry.

The product should therefore not be described as:

left-hand twist

right-hand twist

or:

alternating twist

unless this characteristic has been confirmed for the exact GRN® execution.

For applications requiring directional sealing geometry, this feature should be verified separately.

Selection and Interchangeability

When selecting the GRN® 90x110x15 NBR TC seal, verify:

• shaft diameter d: 90 mm
• outside diameter D: 110 mm
• width B: 15 mm
• elastomer NBR
• TC double lip construction
• spring-loaded primary sealing lip
• auxiliary dust lip
• operating medium
• operating temperature
• shaft surface speed
• pressure
• shaft surface condition
• housing bore dimensions and condition

Matching only the:

90x110 mm

diameters is insufficient to establish technical interchangeability.

The complete 90x110x15 mm dimensions and the seal construction should be considered together.

Technical Specification

FAQ

What are the dimensions of the GRN® 90x110x15 NBR TC seal?

The nominal dimensions are d: 90 mm, D: 110 mm, B: 15 mm, giving the complete size 90x110x15 mm.

Is GRN® 90x110x15 NBR TC a double lip shaft seal?

Yes. It is a TC double lip rotary shaft seal with a primary sealing lip and an auxiliary dust lip.

Does GRN® 90x110x15 have a garter spring?

Yes. The primary dynamic sealing lip is supported by a garter spring.

Does the TC design have a dust lip?

Yes. This GRN® TC construction incorporates an auxiliary dust lip in addition to the primary sealing lip.

What does NBR mean?

NBR stands for Nitrile Butadiene Rubber, a family of technical elastomers widely used in sealing applications.

What is the difference between GRN® 90x110x15 and 90x110x10?

Both have a 90 mm shaft diameter and 110 mm outside diameter, but their widths differ: 15 mm versus 10 mm. They are separate dimensional variants.

Is a 90x110x15 seal interchangeable with a 90x110x15.5 seal?

Automatic interchangeability should not be assumed. The width differs, and the seals may also have different materials, profiles and construction features.

Does TC specify left-hand or right-hand rotation?

No. The TC designation alone does not confirm left-hand, right-hand or alternating hydrodynamic sealing geometry.
