Eine Einführung in das Thema Lubrication Management
(Language: German)

Dieses White Paper soll einen Überblick zum Thema Lubrication Management mit dem Blick auf heutige Dichtungslösungen geben. Es stützt sich auf das Fachwissen sowohl innerhalb von Trelleborg Sealing Solutions als auch in der Hydraulik, um einen neuen Ansatz in der Tribologie von Dichtsystemen zu zeigen.

Ein Punkt, an dem Sie sich in der Welt der Tribologie, also dem Zusammenspiel von Dichtung, Gegenlauffläche und Schmiermedium mit einem größeren Wissen und einer besseren Grundlage auseinandersetzen können - von ihrer Geschichte und Entwicklung bis hin zu den neuesten Lösungen und Ansätzen aus dem Hause Trelleborg Sealing Solutions.

An Introduction to Lubrication Management
(Language: English)

This white paper is designed to be a useful overview of lubrication management through the lens of sealing solutions. It draws on the expertise both within Trelleborg Sealing Solutions and in the wider industry to provide a ‘jumping-off point’ in tribology. A point at which you can deal in the world of sealing and lubrication with a greater knowledge and grounding – from its history and development to the latest solutions and approaches.

An Introduction to Counter Surfaces

Maximize the lifetime of your hydraulic systems now! 
A new approach is required for the definition of counter surfaces to ensure effective sealing in dynamic applications where chrome plating is replaced by alternative coatings.

The lubrication within the hydraulic system is fundamentally affected by the surface finish of the mating surfaces. Their characteristics will determine the lubrication within the system and therefore the tribological environment.

Eine Einführung in das Thema Gegenlaufflächen

(Language: German)

Maximieren Sie jetzt die Lebensdauer Ihrer Hydrauliksysteme!

Für die Definition von Gegenlaufflächen ist ein neuer Ansatz erforderlich, um eine effektive Dichtwirkung in dynamischen Anwendungen zu gewährleisten, bei denen Verchromungen durch alternative Beschichtungen ersetzt werden.

Die Schmierung innerhalb des Hydrauliksystems wird grundlegend durch die Oberflächenbeschaffenheit der Gegenlaufflächen beeinflusst. Ihre Eigenschaften bestimmen die Schmierung innerhalb des Systems und damit die Tribologie im Dichtsystem.

LSR Technology Accelerating Advanced Driver Assistance Systems

Liquid Silicone Rubber (LSR) injection molding techonology lends itself to Advanced Driver Assistance Systems (ADAS) products. This whitepaper compares the main materials for sealing, damping and protection purposes and then focuses on the LSR benefits and processes.

Flüssigsilikontechnologie (LSR) für smarte Fahrassistenzsysteme
(Language: German)

Flüssigsilikon (LSR) Spritzguss ist eine geeignete Technologie für ADAS-Komponenten. Dieses Whitepaper vergleicht die wichtigsten Materialien und fokussiert sich dabei auf die Vorteile von LSR, sowohl material- wie auch prozesstechnisch.

Fighting Hospital Acquired Infection

  • Applying antibiotic Active Pharmaceutical Ingredient (API) coatings to silicone catheters by spraying or dipping
  • Addition of antibiotic APIs to raw silicone
  • Impregnation of vulcanized silicone with antibiotic API through immersion

This whitepaper outlines these three techniques and presents test results proving the effectiveness of the immersion impregnation method in combining an API with silicone tubing to prevent catheter-associated infections.

Supporting the Advancement of Drug-Eluting Devices

Drug device combination products (defined as medical devices integrated with drugs) can be produced in and by a variety of materials and processes. Silicone is one of the most successful materials used for combination products, particularly for implantable products and is the focus of this whitepaper.
Testing of HFC Fluids on Common Seal Materials in High Temperature Applications

As the oil and gas industry moves to recover more challenging reserves and enters the development of High Pressure High Temperature (HPHT) fields, the risk of fire is increasing. There is therefore a move to the use of water-based hydraulic fluids, which present significant sealing challenges. This whitepaper takes an in-depth look at sealing materials and testing in HPHT environments.
Stick-Slip Solution - The importance of damper integration in dynamic sealing

In this whitepaper, we take a closer look at the problem of stick-slip and how dampers can combat or otherwise minimize it. It must be noted that, academically, there exists very little consensus as to the underlying principles of stick-slip – so, this paper will take a practical perspective, addressing how engineers can use dampers to reduce resultant noise and vibration; once again mastering the force of friction.

Looking Beyond Chemical Compatibility Charts: Matching Plastic and Elastomer Seals with Fluids

By Lucy Heyduk and Tim McCulfor, Trelleborg Sealing Solutions

Chemical compatibility charts are often used as a quick and concise way to match the proper fluid with a seal. However, there is much more to consider with the chemical compatibility of a seal in relation to the fluids in a system.  This information is critical to gaining a reliable and long-lasting seal — and the selection process can be daunting. 


High Modulus Plastics Can Play a Key Role in Off-Highway Vehicles

By Tom Zozokos, Product Line Director, and Beth Figliulo, Fluid Power Segment Manager Americas, Trelleborg SealingSolutions.

Co-injection molding is one technology of interest for those designing hydraulic systems for o!-highway use. This allows two polymers to be combined in a single operation to create multiple functions in onecomponent. A good example is an elastomeric material that acts as a seal and a scraper combined with a stronger thermoplastic material that acts as a bushing or guide ring. This component would be anideal molded rod end in a hydraulic cylinder used in the excavator bucket of an o!-highway vehicle, for instance.


Reducing Risk with Geometric Transition Extrusion

By Dan Sanchez, Product Manager at Trelleborg Healthcare & Medical

In an effort to design smaller, more intricate and complicated medical devices without running afoul of increasingly stringent national and international regulations, many designers are looking to geometric transition extrusions manufactured of high consistency rubber (HCR) silicone. This process reduces total cost of ownership for the original equipment manufacturer while improving part quality and greatly enhancing the types of devices being sought by healthcare medproviders.

Composite Simulation Grows MORE ROBUST

By Kenneth Wong

THE TRANSITION FROM METAL to composite is one of the most recent significant changes in manufacturing.
The former material is isotropic, exhibiting uniform stretching and bending behavior in all directions. By contrast,composites are anisotropic. They stretch, bend and break differently in different directions, based on how the fibers are woven together and how the laminates are bonded. This fundamental difference throws many traditional simulation protocols and practices into chaos.
