For 19 years, GRN oil seals have been supplied to professional and industrial customers in Europe.

Our experience with GRN began in 2007, when we started importing and distributing GRN radial shaft seals. Since then, the range has become part of our long-term industrial sealing business and has been supplied to customers operating in different European markets.

During these years, GRN oil seals have been used in real industrial applications, including by manufacturing companies in Germany and customers in France and other European countries.

One fact is particularly important to us:

Throughout 19 years of supplying GRN oil seals, we have not recorded a quality complaint concerning the GRN oil seals supplied by us.

For us, this long-term experience is more meaningful than introducing GRN simply as another range of industrial seals.

GRN has a history.

GRN Oil Seals – Our Story Started in 2007

TG Ersatzteile Polska Sp. z o.o. was established in 2002. Five years later, in 2007, we introduced GRN oil seals to our product range. Since then, GRN radial shaft seals have been part of our industrial sealing business for 19 years.

The industrial components market has changed significantly since 2007.

Supply chains have become increasingly international, purchasing departments have gained access to more manufacturers and brands, and the ability to compare alternative sources has become much greater.

But one requirement has remained unchanged:

an industrial component must perform its function reliably.

When we started importing GRN oil seals in 2007, our objective was to develop a range of radial shaft seals suitable for professional and industrial customers.

Over the following 19 years, the seals were supplied for maintenance, repair, distribution and industrial applications.

This gave us something that cannot be created through marketing alone:

long-term market experience with the product.

From Import to Long-Term Industrial Supply

Importing a product once is relatively simple.

Supplying the same product range for almost two decades is something different.

Long-term industrial supply requires continuity.

Customers return for the same dimensions. Distributors need products for their regular assortment. Maintenance departments require replacement seals. Manufacturers may need repeated deliveries for production.

A product therefore has to prove itself not only when the first order is placed, but also over subsequent years.

GRN has remained part of our sealing business since 2007.

Today, this history allows us to present GRN not as a newly introduced product, but as a range backed by 19 years of actual supply experience.

Used by Industrial Customers in Europe

Over the years, GRN radial shaft seals have reached customers in different European markets.

Our experience includes supplies to industrial manufacturers in Germany, as well as customers in France and other European countries.

This is important because industrial use provides a different perspective on a product than catalogue specifications alone.

Dimensions, material and seal design can be described in a technical data sheet.

Long-term experience comes only with time.

GRN oil seals have had that time.

They have been supplied, installed and used in real mechanical and industrial applications over many years.

19 Years Without a Recorded Quality Complaint

Quality claims should be based on experience rather than marketing language.

For this reason, we prefer to communicate a simple fact from our own supply history:

Since we started supplying GRN oil seals in 2007, we have not recorded a quality complaint concerning the GRN oil seals supplied by us.

That represents 19 years of our commercial experience with GRN.

We deliberately describe this as our own recorded experience.

It is not a theoretical statement that a mechanical component can never fail. Every seal operates under specific conditions, and its service life depends on correct selection, installation, shaft condition, temperature, speed, pressure, lubricant and many other factors.

What we can say is that throughout our GRN supply history, quality complaints have not been recorded for the GRN oil seals supplied by our company.

For distributors and industrial buyers evaluating a potential supplier, this long-term record can be an important consideration.

What Is a GRN Oil Seal?

GRN oil seals are radial shaft seals designed for sealing applications involving a rotating shaft and stationary housing.

Depending on their design and material, radial shaft seals are commonly used to retain lubricants within mechanical systems and help limit the ingress of external contaminants.

They are widely used throughout mechanical engineering.

Typical applications can include:

• electric motors
• gearboxes
• industrial transmissions
• pumps
• drive systems
• agricultural machinery
• construction machinery
• production equipment
• industrial machinery
• mechanical assemblies
• maintenance and repair operations

The correct seal must always be selected according to the requirements of the individual application.

GRN NBR and FKM Radial Shaft Seals

The GRN assortment includes oil seals manufactured from materials widely used in industrial sealing technology, including NBR and FKM.

NBR is commonly selected for many general industrial applications involving compatible mineral oils and lubricating greases.

FKM provides different material properties and is frequently selected where increased temperature or chemical resistance is required.

Material alone, however, does not determine whether a seal is appropriate.

Selection should consider the complete operating environment, including:

• operating temperature
• shaft speed
• pressure
• lubricant or process medium
• shaft surface
• housing dimensions
• seal construction
• installation conditions

For professional applications, technical compatibility should always be verified before replacing an existing seal.

Why Long-Term Experience Matters to a Distributor

A technical distributor has different requirements from a customer purchasing one individual oil seal.

A distributor needs confidence that a product range can become part of a repeatable business relationship.

This can involve multiple dimensions, recurring orders and customers returning years later for the same type of component.

For bearing shops, industrial suppliers and sealing specialists, GRN can therefore represent more than an individual product.

It can become an additional range of radial shaft seals within an existing industrial portfolio.

Our 19-year history with GRN provides a foundation for developing these relationships with new distributors.

Why It Matters to Industrial Manufacturers

Manufacturing companies evaluate components differently again.

For a purchasing department, the lowest unit price is not necessarily the only objective.

Availability, consistency, technical suitability, continuity of supply and the possibility of establishing an alternative source can be equally important.

GRN oil seals have already been supplied for industrial use in European markets, including to manufacturers in Germany.

We now want to use this experience to develop new relationships with manufacturers looking for radial shaft seals for recurring production requirements.

Companies can submit existing seal references, dimensions, materials, technical drawings and expected quantities for individual evaluation.

GRN as an Alternative Supply Source

Supply-chain resilience has become increasingly important in industrial purchasing.

For some components, having access to more than one potential supplier can provide valuable purchasing flexibility.

GRN can be considered by companies looking to establish an alternative or second source for radial shaft seals.

This should always be approached technically.

An alternative seal should not be selected only because its dimensions appear similar.

Material, construction, sealing lip design and actual operating conditions must also be considered.

When these parameters are correctly evaluated, an additional qualified supply source can help purchasing and maintenance departments reduce dependence on a single procurement channel.

GRN for MRO and Industrial Maintenance

Maintenance departments face another challenge: variety.

One factory may contain machinery from different manufacturers, different periods and different countries.

As a result, maintenance teams can require many different radial shaft seal dimensions.

Some are standard.

Others may be required for older machinery or equipment for which the original component is difficult to source.

A broad oil seal assortment can therefore be particularly valuable for MRO, industrial maintenance and repair operations.

This is one of the areas in which the GRN range can support professional customers.

2007–2026: 19 Years of GRN

Nineteen years is a long time in industrial distribution.

Products change.

Suppliers change.

Markets change.

But experience accumulates.

We began supplying GRN oil seals in 2007. In 2026, we can look back on 19 years of experience with GRN radial shaft seals and their supply to professional and industrial customers.

During this period, GRN seals have been used by customers across European markets, including industrial manufacturers.

And throughout this history, we have not recorded a quality complaint concerning the GRN oil seals supplied by us.

That is the foundation on which we want to build the next stage of GRN development.

More distributors.

More industrial customers.

More international markets.

And long-term B2B partnerships built around a product range that has already been part of our business for 19 years.
