Your benefits at a glance with N-ZAPEX XW

We have achieved cost advantages with the N-ZAPEX XW through the following technological innovations.

• Largest bore sizes, compact design: Thanks to maximum bore capacities and very high torques, the N-ZAPEX XW often allows for the selection of a smaller coupling size for the same application. This saves costs and installation space while also reducing the load on machines and bearings.
• Maximum power density: Top performance figures in the smallest installation space—making the N-ZAPEX XW the most compact gear coupling on the market and ensuring a more efficient machine layout.
• Innovative Hollow O-Ring Sealing Concept: This novel and service-friendly sealing concept ensures fast and cost-effective maintenance, minimizes downtime, and delivers cost advantages. The seal can optionally be replaced without cutting and subsequent sealing by gluing, thereby significantly reducing the effort involved.
• Maximum overload capacity: The XW offers up to 30% more overload capacity than the previous series, ensuring maximum system availability and process reliability, even under the most demanding operating conditions.
• Service advantage: The optimized and compact design of the N-ZAPEX XW significantly simplifies service and handling. Its patented sealing concept enables quick and cost-effective replacement and minimizes downtime. The reduced complexity of parts ensures easy spare parts inventory management and enables leaner processes during service.
• Maximum modularity and variety of variants: The highest level of modularity and widest range of modular options on the market offer tailor-made solutions for every industrial application and requirement. Engineered solutions are just as possible as standard catalog solutions.
• Outstanding performance range: With torques of up to 10 million Nm, the XW combines maximum power transmission with low weight, a compact footprint, and optimal machine design.
• Highest Flender quality: Flender stands for the highest manufacturing and product quality and is among the most sustainable and investment-secure companies worldwide.

Applications

The N-ZAPEX XW is used in rolling mills, roll drives, reel drives, mills, rotary kilns, pumps, mixers, and all demanding applications in the steel and cement industries, mining, energy, and many other industries where—often under harsh conditions—maximum performance, flexibility, and fast service processes are required.
