Trelleborg launches Orkot® C620 high-load composite bearings

Trelleborg Sealing Solutions pushes the boundaries of composite technology with the launch of Orkot® C620, an innovative ultra-low friction bearing material with five times the compressive strength of other Orkot materials for offshore and marine applications.

A high-specification thermoset composite, Orkot® C620 meets the requirements of the most demanding high-load applications. Though strong and light, it withstands high loads and stresses over a long service life.

“Orkot® C620’s optimized properties provide customers with a step change in composite bearings, offering a unique combination of ultra-low friction and a compressive strength of 470 MPa, five times the strength of standard Orkot® materials. It is both stronger and has better friction characteristics than competitor composite materials, and can even challenge many metallic bearings for strength, offering industries such as aerospace the lighter, lower-friction solutions they increasingly demand.”

“Featuring a strong #glassfiber backing with a low-friction Orkot® lining, it builds upon regular Orkot® composite formulations with a unique compound where the properties of the different layers increase load capacity and strength. It does this without compromising weight while reducing friction and eliminating maintenance to maximize efficiency and service life.”

Because of its unique characteristics, Orkot® C620 is an attractive solution across a wide variety of sectors with demanding high-load applications including offshore and marine applications.

For offshore wind turbines, it reduces maintenance requirements for deep-sea mooring connections and provides electrical isolation, enhancing corrosion resistance while resisting high loads from rough ocean currents. In wind turbine pitch cylinders it provides a very low coefficient of friction, allowing smooth operation at high loads and low speeds.

For floating production, storage and offloading (FPSO) mooring infrastructure, Orkot® C620’s advantages include low wear rates in fairhead and tensioner applications, and low friction and minimal stick-slip, making it ideal for slow movements in FPSO turrets and swivel stacks. In mid-water arches, it is strong enough to withstand high loads on supporting risers, cables and umbilicals.

Orkot® C620 also delivers outstanding performance in aerospace applications. It is ideal for landing gear applications, providing the required strength of a comparable metal bearing with significant weight reduction, increasing fuel efficiency and allowing for more passenger and luggage capacity. This is critical in industries like aerospace where every kilo counts as manufacturers focus on ‘lightweighting’ to reduce fuel requirements and improve the sustainability of flying.
