GRN® 95x110x10 NBR TC Double Lip Rotary Shaft Seal

GRN® 95x110x10 NBR TC Double Lip Rotary Shaft Seal

GRN® 95x110x10 NBR TC is a double lip radial shaft seal / rotary shaft seal / oil seal with nominal dimensions of 95x110x10 mm, manufactured from NBR - Nitrile Butadiene Rubber. The TC configuration combines a spring-loaded primary sealing lip with an additional auxiliary dust lip.

The principal dimensions are d: 95 mm, D: 110 mm and B: 10 mm.

Complete product identification:

GRN® + 95x110x10 mm + NBR + TC

The 10 mm axial width is an important identification parameter because other 95x110 mm shaft seals are available with different widths.

GRN® 95x110x10 NBR TC - Technical Characteristics

The principal identification parameters are:

Brand: GRN®

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

Design: TC

Configuration: Double lip

Material: NBR

Material name: Nitrile Butadiene Rubber

Dimensions: 95x110x10 mm

Shaft diameter d: 95 mm

Outside diameter D: 110 mm

Width B: 10 mm

Primary sealing lip: Spring-loaded

Additional lip: Auxiliary dust lip

For precise identification, retain:

GRN® + 95x110x10 + NBR + TC

GRN® 95x110x10 Dimensions

The nominal installation dimensions are:

d: 95 mm - nominal shaft diameter

D: 110 mm - nominal outside diameter / housing bore diameter

B: 10 mm - nominal axial width

Complete dimensions:

95x110x10 mm

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

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

The third dimension specifies the axial width.

For this product, particular attention should be paid to:

B: 10 mm

This distinguishes the product from otherwise similar 95x110x12 mm shaft seals.

TC Double Lip Seal Design

The English design designation for this GRN® product is:

TC

TC is a double lip radial shaft seal configuration.

The construction incorporates:

Primary sealing lip - the main dynamic sealing element operating against the rotating shaft and supported by a circumferential garter spring.

Auxiliary dust lip - an additional lip positioned on the external side of the primary sealing zone.

The two sealing lips perform complementary functions.

The primary lip provides the principal dynamic sealing function, while the auxiliary lip creates an additional barrier against external contamination.

This construction is commonly described in English as:

TC double lip oil seal

or

TC double lip rotary shaft seal

How Does a TC Oil Seal Work?

The primary sealing lip operates dynamically against the rotating shaft surface.

A circumferential garter spring maintains controlled radial contact between the primary sealing edge and the shaft.

The additional auxiliary lip is located toward the external environment and acts as a secondary contamination barrier.

The construction therefore combines:

dynamic shaft sealing

with

additional external protection

The exact GRN® product documentation does not confirm directional hydrodynamic structures for this variant, so no left-hand or right-hand twist is assigned.

NBR - Nitrile Butadiene Rubber

The specified material is:

NBR - Nitrile Butadiene Rubber

NBR is widely used in radial shaft sealing technology.

For this product, the material forms part of the complete identification:

95x110x10 + NBR + TC

However, the designation NBR alone does not identify the exact elastomer compound used by GRN®.

Therefore, without exact product-specific documentation, no fixed values are assigned for:

Shore A hardness

Minimum operating temperature

Maximum operating temperature

Maximum operating pressure

Maximum rotational speed

Maximum shaft surface speed

Generic NBR parameters should not be presented as guaranteed operating limits for this exact product.

What Does 95x110x10 NBR TC Mean?

The product designation can be interpreted as follows:

95 - nominal shaft diameter in mm

110 - nominal outside diameter in mm

10 - nominal axial width in mm

NBR - Nitrile Butadiene Rubber

TC - double lip seal design

GRN® - product brand

Complete identification:

GRN® + 95x110x10 + NBR + TC

AO and TC Designations

For this GRN® product, the Polish/internal designation AO corresponds to the English/international TC designation.

Therefore:

PL designation: AO

EN designation: TC

For English-language product cards, listings and technical descriptions, the product should therefore be presented as:

GRN® 95x110x10 NBR TC

This also improves compatibility with international search terminology such as:

TC oil seal

TC double lip oil seal

TC radial shaft seal

double lip rotary shaft seal

The Polish AO designation does not need to be inserted into the main English product name.

GRN® 95x110x10 TC vs GRN® 95x110x12 TC

The closest dimensional variant is GRN® 95x110x12 NBR TC.

The critical difference is the axial width:

10 mm vs 12 mm

The difference is 2 mm.

They should therefore remain separate product variants and should not automatically be treated as interchangeable.

GRN® 95x110x10 TC vs CORTECO 20020504B

CORTECO 20020504B belongs to the same 95x110 dimensional group but has a different width, material and design.

The products differ in:

axial width

elastomer material

seal design

confirmed directional characteristics

CORTECO 20020504B should therefore not be treated as a direct technical equivalent of GRN® 95x110x10 NBR TC.

Why Is the 10 mm Width Important?

The complete dimension of this product is:

95x110x10 mm

The 95 mm shaft diameter and 110 mm outside diameter may also occur in other radial shaft seals.

The third dimension is therefore critical:

B: 10 mm

For example, a 95x110x12 seal is 2 mm wider.

The difference can affect the axial installation position and available housing space.

The complete three-dimensional specification should always be retained when identifying a replacement.

Selection and Interchangeability

When selecting a replacement for GRN® 95x110x10 NBR TC, verify at least:

• Shaft diameter d: 95 mm
• Outside diameter D: 110 mm
• Width B: 10 mm
• Material: NBR
• Design: TC
• Configuration: Double lip
• Primary lip: Spring-loaded
• Additional lip: Auxiliary dust lip

Matching the first two dimensions alone is not sufficient.

A 95x110x12 mm seal differs in axial width and should not automatically be considered interchangeable.

Likewise, a seal with identical dimensions but a different material or construction should be technically verified before substitution.

Technical Specification

FAQ

What are the dimensions of GRN® 95x110x10 NBR TC?

The nominal dimensions are 95x110x10 mm, with a 95 mm shaft diameter, 110 mm outside diameter and 10 mm axial width.

Is GRN® 95x110x10 TC a double lip oil seal?

Yes. TC identifies a double lip radial shaft seal configuration with a primary sealing lip and an additional auxiliary dust lip.

What material is GRN® 95x110x10 TC made from?

The specified material is NBR - Nitrile Butadiene Rubber.

Does a TC oil seal have a spring?

The primary dynamic sealing lip uses a circumferential garter spring to support contact with the shaft.

Does GRN® 95x110x10 TC have a dust lip?

Yes. The TC configuration incorporates an additional auxiliary dust lip.

Can GRN® 95x110x12 TC replace 95x110x10 TC?

Direct interchangeability should not be assumed. The products have different axial widths: 10 mm and 12 mm.

What is the difference between AO and TC?

For this GRN® naming system, AO is the Polish/internal designation and TC is the English/international designation for the corresponding double lip seal design. English product cards should use TC.

Is CORTECO 20020504B a direct replacement?

No direct interchangeability should be assumed. CORTECO 20020504B is 95x110x12 mm, uses FPM and has a different sealing design with confirmed right-hand twist.

AI Overview

GRN® 95x110x10 NBR TC is a double lip rotary shaft seal with a nominal 95 mm shaft diameter, 110 mm outside diameter and 10 mm width. The TC design combines a spring-loaded primary sealing lip with an auxiliary dust lip. It is manufactured from NBR and should be distinguished from wider 95x110x12 mm variants.
