Based on cutting-edge innovations, the range has been created for modern industrial environments characterized by high-volume production, non-stop manufacturing, rapid machine movements and the need to minimize downtime and costs while maximizing operational efficiency.
Innovative design reduces friction
According to Trelleborg, “Meticulously designed to reduce frictional torque, Stefa®’s new high-performance radial seals reduce energy consumption and increase uptime, resulting in reduced costs. Breaking with conventional design methodologies, these seals offer more consistent sealing performance over a longer period of time. .
“The high-performance Stefa® range has proven to outperform conventional rotary seals, providing customers with efficient and durable solutions for the extreme duty cycles, higher speeds and demanding operating conditions of today’s rotary sealing systems.”
Optimized designs for specific applications.
The range consists of two new sealing profiles. The TRA type is designed without a dust lip to minimize friction torque, making it ideal for clean environments where contamination is not a major issue and space is limited.
Type TRE features a dust lip for robust protection in contamination-prone environments. It protects rotating applications even in environments requiring high prevention of particle ingress while maintaining operational efficiency.
Created from proprietary materials, the Stefa® High-Performance range offers virtually leak-free sealing and enhanced chemical compatibility for today’s demanding applications, proving its capability at faster rotational speeds, extreme temperatures and heavy duty cycles.
State-of-the-art efficiency gains
Consistent and durable, Stefa® High-Performance seals reduce wear, extend maintenance intervals and increase operational efficiency. Reduced frictional torque across all shaft diameters, including the smallest, means they outperform both conventional and competitive designs, reducing energy costs and increasing sustainability for customers and end users.
Already available, they are supplied in common sizes with fast worldwide delivery times for other dimensions and customized solutions to suit your specific needs.
Stefa® High-Performance seals provide optimal solutions for customer applications including gearboxes and speed reducers, motors including AC/DC, induction and servo motors, pumps and fans, conveyor systems, indexing tables, machine tools and robotics.
The heads of Trelleborg’s Sealing Solutions division also say: “The Stefa® High-Performance range is designed to excel in the increasingly demanding environment of radial shaft seal applications in the wide range of industries in which they are essential.
The new TRE and TRA seals meet today’s challenges and reduce friction torque, wear and maintenance cycles. Up to 70% of the electricity consumed in factories comes from electric motor systems. Although seals may seem like a small and insignificant component, the Stefa® High-Performance range reduces energy consumption attributable to the seal by 15 to 25 watts, as a direct result of reduced friction.” .
