Lubrication and sealing are critical areas for the performance of any fluid power application. Therefore, the sealing products that are used within the application are essential for conveying the performance and power required, whether moving earth or manufacturing products. - By Jan Sklucki
BEYOND THE RAW FRICTION PERFORMANCE,

seals are expected to prevent leakage, withstand high and low temperatures and pressures, and absorb forces within cylinders. This combination of requirements is challenging for seals and generally necessitates a complex arrangement of products, including wipers and bearings, all working together in tandem.


Trelleborg Sealing Solutions is more than a simple seal supplier. The company partners with customers across the globe to help them achieve their goals. Its expertise and unique approach to sealing enables it to provide components that are reliable, long-lasting and capable of operating within demanding and harsh operating conditions. To better represent today's offering, a new website with films, detailed information, access to digital tools, and cutting-edge webinars relevant to fluid power has now been launched. The website has been designed to contain a wealth of information that is useful to an engineer when specifying solutions for hydraulic arrangements, all in one place.

Working with Trelleborg

Engineering and Development

Trelleborg Sealing Solutions can operate as a partner for your operations, aiming to improve both applications and business processes. Collaboration between teams at an early stage can ensure that the correct products and solutions are chosen and maximum performance is achieved. Nine R&D facilities globally develop new materials and solutions with engineering teams in your local language to provide support and expertise when implementing them.


Though Trelleborg Sealing Solutions offers one of the broadest ranges of products on the market, custom solutions can be developed on request. World-class analytical testing
laboratories, combined with advanced manufacturing and design processes, such as FEA modeling and rapid prototyping, ensure that you can have confidence in any bespoke components

LUBRICATION MANAGEMENT

Effective lubrication within a sealing system is more than choosing the correct lubricant. By expertly managing the lubrication conditions between all elements of the arrangement, the load on each element can be reduced and the system life increased. Lubrication management as a field, takes a holistic approach to the sealing system, aiming to understand the relationships between the components, surfaces, fluids and friction. Through modifications to the seal design and surfaces, friction properties can be significantly lowered to enhance application performance and extend seal life

SEALING SOLUTIONS FOR CYLINDERS

Hydraulic cylinders can feature a complex arrangements of solutions, engineered to work together for optimal performance. Each element within the system plays an important role, whether preventing fluid from spilling out, preventing ingress of external contaminants or stopping contact where undesirable.

Leakage of fluid from within the cylinder to the outside needs to be stopped as does ingress of external contamination. Transverse forces should be absorbed and metal-to-metal contact avoided.

Material Selection

Trelleborg’s material expertise is key to effective operation of seals. Backed by the polymer expertise of Trelleborg Group, and supported by an international network of engineering and R&D, the material portfolio offers an extensive selection of materials to meet any requirements.


TURCON® – Outstanding Friction Characteristics

 Turcon® is the Trelleborg Sealing Solutions range of proprietary materials based on premium-grade Polytetrafluoroethylene (PTFE). The materials demonstrate low friction, with minimized wear in dynamic and high-speed applications. They are compatible with virtually all media, even at elevated temperatures, and are resistant to aging.

 

TURCITE® – Stick-Slip Free Operation

Turcite® material gives outstanding friction behavior, good load capacity, stick-slip free operation and good resistance to high temperatures and chemicals.

 

ZURCON® – Exceptional Wear Resistance

Zurcon® engineered polyurethane-based materials exhibit outstanding friction characteristics, making them ideal for reciprocating, very slow rotating and oscillating situations where high wear resistance is required.

 

ORKOT® – Advanced Composite Polymers

Orkot® bearing materials are thermoset composites incorporating advanced polymer technologies. These consist of technical fabrics impregnated with thermosetting resins, evenly dispersed solid lubricants and further additives to ensure optimum performance.

 

HIMOD® – Economical Solution for Medium Loads

HiMod® provides an economical solution for applications with medium transverse loads, while giving good wear and compression properties.

SEALING SOLUTIONS FOR PUMPS

Pump applications must prevent leakage and contamination of the system, while ensuring low friction and wear over a long period of time. Radial Oil Seals and Turcon® Glyd Ring® are ideal products for this kind of application.
