Trelleborg rolls out sealing advances for e-mobility

Trelleborg , Sweden – Trelleborg Sealing Solutions will showcase its e-mobility solutions at two major events in the automotive calendar in June, The Battery Show Europe from 18 to 20 June and Dritev from 12 to 13 June.

At both events, Trelleborg will feature its three-layer Rubore washer, an automated fibre placement (AFP) process for rotor sleeves and a radial shaft seal HiSpin EV.

The Rubore washer is highly efficient at sealing and protecting sensitive electrical systems from moisture and corrosion, enabling customers to increase the performance, safety and longevity of their vehicles.

It is manufactured using a special production process in which the carrier metal is vulcanized with a rubber layer on both sides, creating a three-layer laminate that is durable and particularly long-lasting. The washer is available in different diameters and thicknesses to meet manufacturers’ requirements.

Trelleborg will also demonstrate its innovative AFP process for the rotor sleeves of electric motors. It allows thermoplastic fibre composite sleeves to be wrapped directly around rotors in a fully automated process, resulting in thinner sleeves compared to conventional epoxy solutions.

Due to polymer ‘in-situ consolidation’, no additional use of an autoclave is required, enabling customers to utilise a rapid, high-quality manufacturing process to produce large quantities of electric motors with increased performance and efficiency.

New radial shaft seal HiSpin EV features a symmetrical design, offering “excellent sealing performance for both directions of shaft rotation in electric motors.

The seal is designed for shaft surface speeds of up to 40 meters per second/131 feet per second, and has low friction properties, significantly reducing heat generation at high rotational speeds.
