GRN® 90x110x10 NBR TC Double Lip Rotary Shaft Seal

GRN® 90x110x10 NBR TC Double Lip Rotary Shaft Seal

GRN® 90x110x10 NBR TC is a double lip rotary shaft seal with nominal dimensions 90x110x10 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® + 90x110x10 + NBR + TC + double lip

GRN® 90x110x10 NBR TC – Technical Characteristics

GRN® 90x110x10 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: 10 mm – nominal axial width

Complete nominal size:

90x110x10 mm

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

The 10 mm width is particularly important because other GRN® seals are available with the same 90 mm shaft diameter and 110 mm outside diameter but with different axial 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 creates 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 on the external side of the primary sealing zone.

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, this construction may be identified as:

AO

or:

AO/TC

For the English product catalogue, the preferred designation is:

TC

Therefore:

Polish: GRN 90x110x10 NBR AO/TC

becomes:

English: GRN® 90x110x10 NBR TC

Profile codes are not universally standardized between manufacturers. The GRN® TC designation should therefore not automatically be transferred to seals from CORTECO, SKF, Freudenberg/Simrit or other manufacturers.

How Does the GRN® 90x110x10 TC Seal Work?

The radial shaft seal operates between a:

rotating shaft

and a:

stationary housing.

For this product, the nominal shaft diameter is 90 mm, while the nominal outside diameter of the seal is 110 mm.

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

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

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

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 against the actual operating medium and operating conditions.

GRN® 90x110x10 vs GRN® 90x110x8

A closely related GRN® variant is:

GRN® 90x110x8 NBR TC

Both seals have:

d: 90 mm

and:

D: 110 mm

but their widths are different:

These are therefore two distinct dimensional variants.

They should also remain separate SEO and AI Search entities:

GRN® 90x110x10 NBR TC

and:

GRN® 90x110x8 NBR TC

This distinction helps users identify the correct width and prevents unnecessary search cannibalization between the two product pages.

Does TC Specify Rotation Direction?

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

The product should therefore not be described as:

right-hand twist

left-hand twist

or:

alternating twist

unless this characteristic is confirmed for the exact GRN® execution.

For applications requiring a directional shaft seal, the rotation-related design must be verified separately.

Selection and Interchangeability

When selecting the GRN® 90x110x10 NBR TC seal, verify:

• shaft diameter d: 90 mm
• outside diameter D: 110 mm
• width B: 10 mm
• elastomer NBR
• TC double lip design
• 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 the 90x110 mm diameters alone is insufficient to establish technical interchangeability.

In particular, 90x110x8 and 90x110x10 should not automatically be treated as interchangeable simply because they share the same shaft and outside diameters.

Technical Specification

FAQ

What are the dimensions of the GRN® 90x110x10 NBR TC seal?

The nominal dimensions are d: 90 mm, D: 110 mm, B: 10 mm, giving the complete size 90x110x10 mm.

Is GRN® 90x110x10 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® 90x110x10 NBR TC have a garter spring?

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

Does the TC design have an auxiliary dust lip?

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

What does NBR mean?

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

What is the difference between GRN® 90x110x10 and 90x110x8?

Both have a 90 mm shaft diameter and 110 mm outside diameter, but the axial width is different: 10 mm versus 8 mm. They are separate dimensional variants.

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.

How should a GRN® 90x110x10 shaft seal be selected?

Verify the complete 90x110x10 mm dimensions, NBR material, TC double lip construction and the operating requirements of the specific sealing application.
