Trelleborg Sealing Solutions has introduced the Turcon SG rotary seal range, specifically engineered for the demands of central tire inflation systems in off-highway vehicles. The assembly is designed to maintain airtight performance while managing pneumatic pressure during continuous rotary motion.
Why it matters
By facilitating automatic tire pressure adjustments, the seal supports up to 15% reduced fuel consumption and lower CO2 emissions for heavy machinery. It resolves the engineering challenge of maintaining seal integrity under constant pressure and rotation.
The Turcon SG seal remains in a near-zero-friction state for 90-95% of its operating cycle and provides an extended service life exceeding 10,000 hours. The design allows for a 15% reduction in vehicle fuel consumption.
The players
Trelleborg Sealing Solutions
This global engineering firm specializes in advanced polymer sealing technologies for the automotive, aerospace, and industrial sectors.
The details
The component integrates a static elastomer seal with a guiding element in a modular, compact assembly. Its pressure-activated mechanism ensures the sealing lip remains in an unpressurized state until active inflation or deflation cycles begin.
Timeline
Trelleborg Sealing Solutions launched the product line on October 7, 2026.
Roadmap
This release reflects an industry-wide push to optimize off-highway vehicle efficiency through the integration of precision-engineered components. It signals a move toward modular, high-durability assemblies that challenge traditional maintenance intervals in heavy-duty machinery.
Fleet operators and heavy vehicle owners can expect lower maintenance overhead due to the extended 10,000-hour service life of the seals. Furthermore, the 15% improvement in fuel efficiency offers a direct reduction in long-term operational costs for off-highway equipment.
The takeaway
This technology highlights how small-scale component engineering can significantly impact the sustainability metrics of heavy industries. Operators should prioritize modular, pressure-activated seals to maximize machinery uptime and reduce unnecessary fuel expenditures.
