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.

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.
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.
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.
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.
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.
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.
(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.
Technical Articles
By David Kaley — Trelleborg Sealing Solutions; Edited by Mike Santora
With stainless steel and other metals so predominant in industrial food manufacturing equipment, it may seem unusual to suggest a more significant role for plastic wear rings and bearings. But for a broad range of food production and transportation machines, advanced polymers are an effective way to reduce friction and handle load instead of traditional metal bearings.
By Harlan Hart, technical manager, e-mobility, Trelleborg SealingSolutions.
Recognising that a specialised sealing solution was needed for e-Mobility applications, Trelleborg Sealing Solutions has developed two new seals that could help noticeably extend the distance travelled by electric vehicles between charges, as Harlan Hart, technical manager, e-Mobility, explains

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.
5 medical tubing manufacturing processes to achieve complex geometries
By Dan Sanchez, Trelleborg Healthcare & Medical
Medtech companies have demanded increasingly complex geometries in medical tubing. Here’s a rundown of five manufacturing processes that could help them get there.
Trelleborg Sealing Solutions has developed a unique engineered seal– specifically for use within Central Tire Inflation systems. Turcon® Roto L is the first ever active seal, engineered to only provide sealing when required. Eliminating friction and torque, this extends the seal life of axle systems and can significantly reduce fuel consumption for vehicle operators.
Modern machinery, equipment and motors fitted with hydraulic cylinders are becoming more powerful, which means that the hydraulic systems therein are increasingly subject to higher operating pressures and temperatures.

The chemical compatibility of a seal with the fluids in a system is critical to obtaining a reliable, long-lasting seal. Here are some considerations for choosing the right material for a given chemical sealing application.
New developments in sealing technology require the use of advanced design techniques, and a complete solution requires pre-processing, solution and post-processing for effective nonlinear Finite Element Analysis.
Finite Element Analysis (FEA) software is used to create computer-generated models of materials or design components. These are then subjected virtually to mechanical, thermal or other stresses so that engineers can predict material and product performance.
Stick-slip is not always a big issue, but sometimes it can significantly
