N-ZAPEX XW – A new benchmark for advanced customer requirements

The N-ZAPEX XW sets new standards for gear couplings up to the high-performance range and for engineered solutions. Its innovative, patented hollow O-ring sealing concept enables simplified seal replacement and can thus reduce your maintenance costs. With maximum modularity, the widest range of variants on the market, and maximum torques of up to 10 million Nm, the XW is the perfect solution for joint-critical applications across major industrial sectors.

 

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: High performance data in small installation space—with its compact design, the N-ZAPEX XW can provide for a more efficient equipment 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. The sealing concept allows simplified seal replacement and can reduce maintenance costs and downtimes. 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 unites high power transmission with a compact design and optimized machine layout.
• Highest Flender quality: Flender is dedicated to the highest manufacturing and product quality.

 

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.

 

Did you know?

With the N-ZAPEX XW, you can save twice—in the initial investment and in service. You choose a platform that not only sets technical standards in a market comparison, but also offers high cost and service efficiency. The reduction in size and weight can minimize machine wear, simplify installation, service, and spare-parts stocking, and ensure that you optimally protect your investment.
