What is a TC oil seal?

A TC oil seal is a commonly used double-lip radial shaft seal construction.

Its characteristic design consists of:

• elastomer-covered outside diameter
• spring-loaded primary sealing lip
• additional secondary dust lip
• internal reinforcing metal case

The primary lip is designed to retain the lubricant or other compatible medium on the fluid side.

The secondary lip acts primarily as a dust and contamination exclusion lip.

This makes the TC profile one of the most widely recognized double-lip oil seal designs.

TC oil seal construction

The main functional elements of a TC radial shaft seal are:

1. Primary sealing lip

The primary lip runs directly against the rotating shaft and performs the main sealing function.

Its geometry is designed to create a controlled sealing contact with the shaft surface.

2. Garter spring

The primary sealing lip is supported by a garter spring.

The spring helps maintain appropriate radial contact between the sealing edge and the shaft.

3. Secondary dust lip

The second lip is positioned toward the external side of the seal.

Its principal function is to help prevent:

• dust
• dirt
• fine particles
• external contamination

from reaching the primary sealing lip.

4. Metal reinforcement

The internal metal case provides structural rigidity and helps maintain the geometry of the radial shaft seal.

5. Rubber-covered outside diameter

In a standard TC construction, the metal case is covered externally with elastomer.

This creates a rubber-covered outside diameter for installation in the housing bore.

TC means double lip oil seal

The TC construction is commonly described as:

double lip oil seal

because it incorporates two functional lips:

Primary lip - spring-loaded sealing lip responsible for retaining the operating medium.

Secondary lip - additional dust lip intended primarily to protect the main sealing area from external contamination.

Therefore, useful international product descriptions include:

• TC oil seal
• double lip oil seal
• double lip shaft seal
• radial shaft seal with dust lip
• spring-loaded oil seal with dust lip

NBR - Nitrile Butadiene Rubber

GRN 80x105x13 TC is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomer materials for conventional radial shaft seals.

It is commonly used with compatible:

• mineral oils
• lubricating oils
• greases

and in many standard industrial sealing applications.

Suitability must always be checked against the actual medium, temperature, shaft speed and operating conditions.

Why is NBR widely used for oil seals?

NBR offers a useful combination of properties for many conventional industrial sealing applications, including:

• good resistance to many mineral oils and greases
• good mechanical properties
• good abrasion resistance
• practical flexibility
• broad use in standard machinery
• economical sealing performance

For these reasons, NBR is frequently used in TC radial shaft seals for general industrial applications.

NBR TC oil seal applications

GRN NBR 80x105x13 TC can be considered for appropriately designed sealing positions in equipment such as:

• industrial gearboxes
• speed reducers
• electric motors
• drive systems
• pumps
• agricultural machinery
• construction machinery
• production equipment
• mechanical transmissions
• industrial machines
• rotating shaft assemblies

These are general application categories.

Compatibility with a specific machine must be determined from the technical requirements of the sealing position.

TC vs SC oil seal

One of the most important distinctions in common international oil seal terminology is:

SC - single lip

TC - double lip

A typical SC oil seal has a spring-loaded primary sealing lip without the additional external dust lip.

A typical TC oil seal has:

• spring-loaded primary sealing lip
• additional dust lip

Therefore:

80x105x13 SC

and:

80x105x13 TC

are not identical constructions.

If the original application requires a dust lip, this feature should be considered when selecting the replacement.

TC vs AO designation

The same general double-lip radial shaft seal concept can be described using different designation systems.

For this GRN product:

TC is used as the international construction designation.

AO may be encountered as a corresponding designation in European technical terminology.

For international SEO, technical searches and product identification, the preferred name is:

GRN NBR 80x105x13 TC Double Lip Oil Seal

Search variants containing AO can still be useful for customers searching according to another seal designation system.

NBR vs FKM/FPM

A TC oil seal can be manufactured from different elastomers.

For example:

NBR TC

and:

FKM/FPM TC

describe a similar general construction but different sealing materials.

NBR and FKM/FPM differ in their chemical and thermal properties.

Therefore, an FKM/FPM seal should not automatically replace an NBR seal, or vice versa, solely because the dimensions and TC construction are identical.

NBR vs VMQ

NBR and VMQ are different elastomer families.

NBR is nitrile rubber.

VMQ is silicone rubber.

Consequently:

NBR TC 80x105x13

and:

VMQ 80x105x13

should not automatically be considered technically interchangeable.

Material selection must correspond to the operating conditions.

GRN 80x105x13 TC vs CORTECO 19016575 VMQ LHTC

Both products can have nominal dimensions:

80x105x13 mm

but they should not automatically be considered interchangeable.

The GRN product described here is:

NBR TC

whereas CORTECO 19016575 is specified as:

VMQ LHTC

Important differences include:

• elastomer material
• sealing profile
• lip geometry
• directional characteristics
• intended application

Identical dimensions do not establish technical equivalence.

Why dimensions alone are not enough

Many different radial shaft seals can share the dimensions:

80x105x13 mm

They may differ in:

• material
• profile
• number of lips
• spring configuration
• outside diameter construction
• dust lip
• directional features
• temperature capability
• medium compatibility
• application

For correct selection, the complete designation should be checked.

How to select an 80x105x13 TC oil seal

Before ordering, verify:

• shaft diameter: 80 mm
• housing bore: 105 mm
• seal width: 13 mm
• required material: NBR
• required construction: TC
• need for an additional dust lip
• operating medium
• operating temperature
• shaft speed
• shaft surface condition
• housing condition
• original seal specification

The best replacement is selected by matching the complete technical specification rather than dimensions alone.

Installation of GRN 80x105x13 TC

Before installation, clean and inspect both the shaft and housing.

Check the shaft sealing surface for:

• wear grooves
• scratches
• corrosion
• burrs
• sharp edges
• contamination
• mechanical damage

The seal should be pressed squarely and evenly into the housing using an appropriate installation tool.

Avoid deforming or tilting the seal.

Protect the primary sealing lip

During installation, the primary sealing lip must be protected against:

• sharp shaft edges
• threads
• splines
• keyways
• grooves
• burrs

An appropriate installation sleeve should be used where required.

Damage to the sealing edge during assembly can cause leakage immediately or significantly shorten service life.

Check the shaft sealing track

The shaft surface directly beneath the primary sealing lip is critical to correct operation.

Inspect it for:

• wear grooves from the previous seal
• scratches
• corrosion
• excessive wear
• surface damage

A worn shaft can cause leakage even after installation of a new radial shaft seal.
