Trelleborg Launches Ground-Breaking Stefa® High-Performance Radial Shaft Seals
Trelleborg Sealing Solutions recently announced the launch of the innovative Stefa® High-Performance Radial Shaft Seal portfolio designed to redefine performance standards under extreme application conditions. Built on cutting-edge innovation, the range has been created 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. “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. “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.” 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 isn’t 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. Available now, they are stocked in common sizes with rapid global lead times for other dimensions and custom solutions to meet your specific requirements. “The Stefa® High-Performance range was designed to excel in the increasingly tough applications environment for radial shaft seals across the wide range of industries where they are essential,” said David Kaley, Global Segment Manager Industrial Automation. “The new TRE and TRA seals meet today’s challenges while reducing frictional torque, wear and maintenance cycles. Up to 70% of electricity used in factories comes from electric motor systems. While seals might seem like a small, insignificant component, the Stefa® High-Performance range reduces power consumption attributable to the seal by 15-25 W, a direct result of reduced friction.”
