Treating Elastomers using Nanotechnology Close cooperation

At the beginning of this year I assumed new duties and am now responsible for Simrit's international business. I am pleased to be devoting myself to this area because I know I can continue to count on its smoothly functio- ning team and efficient organization. This change in management will not mean a change in direction. We will continue to apply our strategy of precisely matching our business activities to customer needs, market segments and regions—to combining global orientation with local presence. The new issue of Simrit Insight, in which we report on Simrit projects in Brazil (page...

Germany's main customs office in Karlsruhe has granted the status of "Authorized Economic Operator" (AEO) to Freudenberg Sealing Technologies GmbH & Co. KG, holder of the Simrit trademark. The company received the most comprehensive version of the certificate, the AEO F (customs streamlining/security), which is valid throughout the entire European Union. Freudenberg Sealing Technologies is now listed in the European Commission's registry of AEO-certified companies. The status of "Authorized Economic Operator" is a key element of the EU's international trade security concept. Authorized...

Even better product protection, trade- mark visibility all the way to the final consumer and trackability right down to the individual part level are some of the highlights of a new Simrit packaging concept. Two packaging types will be used in the future: large packaging sys- tems focusing on the needs of industry and small packaging systems mainly focusing on the needs of Simrit distribu- tors. In the course of the changeover, new article numbers will be assigned for about 4500 articles. These new ar- ticle numbers will be correlated with the given packaging unit being used. Since the...

Just how small are these details? In- credibly small: between the width of a single atom and minuscule struc- tures a few nanometers in size. The secret behind this devilishly critical detail is RFN® (Reduced Friction by process developed by Simrit for sur- face treating elastomers. When RFN® is used in...

Simrit's innovative RFN® treatment is based on nanotechnology. It impacts such key parameters as friction, wear and wettability. Continually bigger and better? It was not too long ago that superlatives al- ways had something to do with physi- cal size. Things are different today. Hi-fi systems no longer fill up the whole wall.

FULL SAIL The special crane hoisting vessel INNOVATION, put into service in the summer of 2012, has revolutionized the construction of offshore wind turbines. The rack-and-pinion gears used here, made by Siemens Mechanical Drives (MD), and the gears' sealing components play an important role in this technical advancement. Offshore wind turbines are at "full sail". The German government's ener- gy plan has established a target output is to be generated through these kinds of coastal wind turbines. In 2030, the plan assumes an output of 25,000 MW. In order to achieve this ambitious goal,...

The rack-and-pinion gears in the special crane hoisting vessel INNOVATION enable a lifting speed of up to 1 m/min. Up to 7 wind turbines (output class More installation capacity With the special crane hoisting vessel INNOVATION, the installation capac- ities for construction coastal wind tur- bines has increased fourfold in a sin- gle blow. Siemens MD, as the central gear supplier, and Simrit as the seal- ing specialist, have certainly helped to make the ambitious goals set out by the German government, for ener- gy production through wind energy, • Special INNOVATION type crane hoisting...

TESTING TAILOR MADE Comprehensive tests are indispensable when it comes to ensuring the quality of products. That is why Simrit have always had diverse, state-of-the-art test stands and testing equipment. Now the sealing specialist is going a step further and is, for example in cooperation with Eaton Hydraulics, making test stands available which are tailored to the actual customer applications. • New testing equipment for radial shaft seals is designed to perfect- ly match the customer's individual application specifications • Together with their customer Eaton Hydraulics, Simrit have now...

Eaton products enables Simrit customer's needs and to verily his concepts. That accelerates trials. It is, for example, possible to replicate pressure spikes and rota- tional speeds, allowing the Simrit spe- cialists to gain a more accurate un- derstanding of inputs (side load, pressure spikes, shaft interface, etc.) and to obtain key data regarding life expectancy of the seal. The collected data forms the basis for the develop- ment of new seal designs that improve Testing for customer needs These types of trials are typically con- ducted on the customer's equipment, not by the seal...
