SURPRICE. THE STANDARD SETS THE PRICE.

• N-ZAPEX XN Double-jointed Gear Coupling – The new standard for efficiency, compactness, and cost-effectiveness in large and demanding industrial applications
• Rated torque range: TKN = 1,400 Nm to 245,000 Nm across twelve sizes
• Temperature range: –30 °C to +80 °C

The N-ZAPEX XN Gear Coupling, developed by Flender, is a high-performance double-jointed gear coupling engineered for small to medium sizes and demanding industrial applications

Constructed with premium high-grade steel components, the coupling features a compact, lightweight design that simplifies installation, handling, and spare parts management[1][

A core advantage is its exceptional misalignment compensation capacity—60% higher than Flender’s previous ZAPEX ZN series—effectively accommodating angular and radial shaft misalignments to ensure maximum system availability and safety[1]

The N-ZAPEX XN Gear Coupling features reusable components and standardized modular parts, further optimizing lifecycle costs and simplifying inventory management

Common applications include rolling mills, roller conveyors, and reels in the steel industry; mills and rotary kilns in cement and mining; cranes, hoists, slurry pumps, and kneaders[1]. It excels in applications where compactness, efficiency, and cost-effectiveness are prioritized. Overall, the N-ZAPEX XN Gear Coupling is a reliable, high-performance solution that balances compact design, high misalignment capacity, and cost-efficiency, delivering sustainable and economical power transmission for diverse industrial challenges worldwide.

Maximum standard. Minimum price.

The N-ZAPEX XN gear coupling securely connects machine shafts and reliably compensates for angular and radial misalignment. It sets new standards in compactness, power density, and standardization—making it the most technically advanced gear coupling in its class. Manufactured from high-quality steel, it meets the highest requirements for reliability, durability, and investment security.
