Trelleborg celebrates the birth of Rubore® technology 25 years ago

Powertransmissions - Trelleborg celebrates the birth of Rubore® technology 25 years agoFrom its humble beginnings in the kitchen of Percy Josefsson, the Rubore® process is now used in brake shims to damp brake noise on the majority of cars worldwide.


On 29 June 2013, Trelleborg celebrated the 25th birthday of Rubore® technology at its birthplace in Kalmar, Sweden.

Stefan Lundström, President of Damping Solutions at Trelleborg, says: “We are very proud of the unique Rubore® technology and in particular that after 25 years it continues to meet the ever increasing demands of our automotive customers. Though the principles behind the process remain the same, we are continually challenging ourselves to provide innovations in applications for the technology and we see major opportunities for the product globally.

The birthday celebrations were attended by numerous Trelleborg personnel from around the world including President of Trelleborg Sealing Solutions, Claus Barsoe and Senior Vice President, Corporate Communications for Trelleborg Group, Patrik Romberg.

Rubore® technology is an advanced production process used to create a three to five layer rubber-to-metal sandwich by applying a bonding agent to metal carriers and then vulcanizing rubber to the coated metal.

It is world-leading in anti-vibration applications for the automotive industry and its use has now been extended into a range of advanced Rubore® seals for automotive applications. The process allows for development of components that offer significant weight-savings and unrivalled total cost reduction that are only achievable through this method of production.

Trelleborg – NEW – Sealing technology e-learning now available.

Powertransmissions - NEW Sealing technology e-learning now available

As part of a continuously growing, comprehensive learning offering for customers on the web, Trelleborg Sealing Solutions launches two e-Learning modules: “O-Rings” and “Hydraulic Seals”. Each module consists of three to four lessons focusing on different aspects, such as, material selection or application layout.

“Future e-learning modules will cover the basics of sealing technology for all major sealing product areas,” says Robert Zahiri, Director Global Marketing and Communications. “Our aim is to answer questions most commonly asked by design engineers when facing sealing challenges.”

Introductory lessons for the e-learning modules can be accessed free of charge by everyone. The complete e-learning modules are available by buying a subscription or using a Trelleborg voucher code to access the complete learning modules.

The e-learning program from Trelleborg Sealing Solutions will be expanded progressively. Next in the schedule are modules on “Rotary Seals” and “Seal Installation Instructions”, to be released later this year.

Take a quick look! Here are the introductory lessons for the first two learning modules:

Trelleborg to slash downtime with new SealWelding technology

Trelleborg to slash downtime with new SealWelding technologyTrelleborg has launched a revolutionary new SealWelding technology which allows seals to be welded in-situ on an FPSO platform, eliminating the need for it to disconnect and return to shore.

Manufactured from Trelleborg’s already well-established seal material, this new technology will massively reduce the downtime and associated costs that come from maintaining an FPSO swivel stack. Currently, swivel stack maintenance requires a vessel to travel back to shore so that components can be completely disassembled and seals replaced.

“The offshore oil and gas sector has been going strong since the late 1940s, however, as the industry continues to move toward even more demanding offshore applications in order to drill deeper and reach further, the use of floating production, storage and offloading vessels have become particularly popular in recent years. While these offshore facilities have opened the potential of oil and gas exploration and production, maintaining them can often prove difficult and time consuming, especially as environments become more challenging,” commented Henk-Willem Sanders, Technical Manager Europe, Trelleborg Sealing Solutions.

“This is because with a number of component failures able to easily lead an FPSO to a shutdown that requires onshore maintenance, the cost and travelling time required to return an FPSO to shore can very quickly add up. In fact, when maintaining the swivel stack, a critical element onboard any facility, typically the FPSO would be down for between six and 12 weeks and the cost of that could rise to 100s of millions of dollars.

In situ maintenance

“With seals playing a vital role when it comes to ensuring the continued efficient and safe operation of an FPSO swivel stack, the industry has been looking for a way to solve the issue of onshore maintenance by developing a practice which would allow operators to remove and replace the seal in situ on the FPSO offshore – and I am pleased to announce that with our new technology, we have more than met the challenge.”

By optimizing billet welding, Trelleborg’s new technology is able to weld the original seal material in-situ. In a controlled manufacturing area, Trelleborg starts the process by producing a seal which has been cut in one place using a specially designed tool. The product is then packed so that it is well protected and avoids any damage in transit.

Offshore, onboard the FPSO, the seal is unpacked and installed onto the swivel by highly trained personnel from Trelleborg’s service team; the skilled engineer installs it in the Weld Head Enclosure (part of the welding machine) which, certified to ATEX zone 1, is then pressurized so that the welding can take place. Fully enclosed, production on other swivel stacks can continue without risk.

Smooth running

A Control Cabinet, which is purged and will also be certified to ATEX zone 1, ensures the smooth running of the process, as well as monitoring and logging all data. After the process is finished, the seal is safely removed from the Weld Head Enclosure before being polished and checked. If the values from the recorded data are satisfactory, the seal will be released for installation.

Henk-Willem continued: “We are confident that our new fully tested and portable system is not only set to make life for the offshore operator safer and easier, but also dramatically improve the bottom line for the oil company.”
