Trelleborg launches Stefa High-Performance Radial Shaft Seals
Trelleborg Sealing Solutions launches the innovative Stefa High-Performance Radial Shaft Seal portfolio designed for modern industrial environments characterized by high-volume production, 24/7 manufacturing, rapid machinery movement and the necessity to minimize downtime and cost while maximizing operational efficiency.

Trelleborg’s Stefa High-Performance Radial Shaft Seals.
Meticulously engineered to reduce frictional torque, the new Stefa High-Performance Radial Shaft Seals lower energy consumption and increase uptime. Breaking conventional design methodologies, these seals deliver more consistent sealing performance over a longer period of time.
“The Stefa High-Performance portfolio is proven to outperform conventional rotary seals, providing customers with efficient, durable solutions to the extreme duty cycles, higher speeds and challenging operating conditions of today’s rotary sealing systems,” said Inderjeet Singh, Global Product Line Director Rotary Seals at Trelleborg.
Optimized application-specific designs
Two new sealing profiles make up the range. The TRA type is designed without a dust lip for minimal frictional torque, making it ideal for clean environments where contamination is not a significant concern and space is limited.
The TRE type features a dust lip for robust protection in contaminant-prone environments. It protects rotary applications even in environments that require high ingress prevention while maintaining operational efficiency.
Created from proprietary materials, the Stefa High-Performance portfolio offers virtually leak-free sealing and wider chemical compatibility for challenging applications, proving their capability at faster rotary speeds, in harsh temperatures and across heavy-duty cycles.
