The reduced friction with Seal-Glide Nano for surface coating enables shock absorbers to react quicker and adjust to radial movements; faster the suspension reacts to the road surface, the better and more secure the handling of a vehicle, claims the company

Shock absorbers are critical damping elements in vehicles as they ensure good control and safe handling by damping unwanted body movements while maintaining a constant contact with the road for tyres. Trellebrog has introduced Seal-Glide Nano, a coating specifically designed to reduce friction in shock absorbers that is claimed to extend seal life significantly.

Seal-Glide Nano is an extremely thin coating with the effectiveness of the shock absorbers. At around 450 nanometers thick, it is ten to 50 times thinner than typical coatings. Its main superpower is to significantly reduce the friction coefficient of elastomer seals and improve their stickslip properties substantially without affecting the original properties of the seals. Ultimately, that means that seals coated with Seal-Glide Nano have a higher service life due to reduced friction when in motion or during installation.

Seal-Glide Nano utilises a proprietary process to apply a nanoscale coating layer on the surface of a seal. This provides for easy handling by preventing sticking, which is a significant advantage during automated assembly. In comparison with thicker coatings, Seal-Glide Nano offers a lighter touch that is applicable for any kind of elastomer and geometries.

Neal Borg, Product Manager, Trelleborg Sealing Solutions in Malta, said the application of SealGlide Nano will provide a clean and dry solution, which not only reduced assembly forces but also improved the feed rate in automated assembly lines, thereby creating benefits in the sealing functionality of this ride-control application.

Low friction is also a key point for manufacturing, as shock absorbers are produced in high volume in automated processes. The quicker these operate, the better the turnaround times and factory output.
