Trelleborg Introduces Stefa® High-Performance Radial Shaft Seals

Trelleborg Sealing Solutions has launched the Stefa® High-Performance Radial Shaft Seal portfolio, a new range engineered for demanding industrial applications. Developed for environments that demand high output, continuous operation and reduced downtime, the seals are designed to extend service life while lowering energy consumption and maintenance requirements. Two variants, the TRA and TRE types, address different application conditions, from clean spaces to contamination-prone settings.

The new designs incorporate proprietary materials and manufacturing methods to deliver consistent sealing performance at higher speeds and under harsher operating conditions. By minimising frictional torque, the seals aim to improve efficiency across a wide array of equipment, including motors, pumps, fans, gearboxes, conveyors and robotics. Global availability in standard sizes and custom options further supports their use across multiple industries.

“Meticulously engineered to reduce frictional torque, the new Stefa® High-Performance Radial Shaft Seals lower energy consumption and increase uptime, lowering costs. Breaking conventional design methodologies, these seals deliver more consistent sealing performance over a longer period of time.” said Inderjeet Singh, Global Product Line Director Rotary Seals.
