MFlex 7

The all-rounder for all applications

Safe tracks? Durability? Optimized life cycle costs? All combined in MFlex 7!

LOW MAINTENANCE. EASY TO INSTALL. HIGH PERFORMANCE.

Operational requirements are constantly increasing, regardless of whether it's conventional or high-speed rail lines or heavily used routes. Conventional fastening systems are increasingly reaching their limits, resulting in material fatigue and shorter life cycles. For us, these challenges were the starting point for a new development.

 

The solution is called M-Generation. As an innovative component of the system MFlex 7, the M7 distributes forces evenly, protecting not only itself but the entire system. This ensures maximum stability, minimizes maintenance and extends service life, even under demanding conditions.

 

The MFlex 7 combines technical robustness with ecological and economic advantages – an all-rounder for the mobility of tomorrow.

Reliability is a top priority – on every track

Economy, safety, and futureproofing are perfectly combined in state-of-the-art design and function – for maximum performance with minimum maintenance.

Safety and availability of routes are our priorities.

Maximum track stability: significantly increased torsional resistance through innovative M-geometry with outwarded springarms

Longer service life: > 1,500 Hz natural frequency ensures maximum robustness

Sustainable track construction: M7 uses innovative, micro alloyed steel and compact design to reduce CO₂ emissions

Welcome to the new era of track construction!

Impressive wherever performance counts

Whether High-Speed, Conventional Rail, turnouts, or crossings — in any position and on any inclination. Our MFlex 7 is designed for versatile use and the most stringent demands.

For permanently high track availability — with minimal maintenance.

 

Flexible planning, quick installation– Every track and every situation

Maximum flexibility: adaptable to any application

Quick installation: can be delivered pre-assembled directly to the construction site

Low maintenance & long service life: components, including dowels, can be replaced individually

Height & track adjustment: precise gauge regulation and easy position correction within the system

 

Innovative design - Maximum performance along the entire track

Secure fastening: M7 ensures reliable load distribution and precise gauge regulation

High load capacity: middle bend as an additional tilting protection and a secure screw-dowel connection for a permanently secure fixation, even under high loads

Optimal load distribution: forces are evenly distributed and transferred to the superstructure – for stability and a long service life

Robust even under heavy loads: high push-through and torsional resistance, as well as natural frequency

From complexity to efficiency: fully compatible with existing W-systems to reduce complexity on the track

cellentic & Vossloh protect: Higher performance. Less effort.

cellentic - Maximum rail deflection. Optimal load distribution. Tilting protection.

Reliable damping of structure-borne noise and forces – resistant to all environmental conditions.

 

Vossloh protect – Environmentally friendly. Maximum protection. Longer service life.

Effective corrosion protection against moisture, salt, and environmental influences for long-lasting components and reduced life cycle costs.

 

Angled Guide Plate High Torsional Resistance (HTR) – Greater safety. Increased availability. Resource efficiency.

Increased protection against track buckling and wear – even on tight curves and challenging superstructure.

 

Screw-Dowel Combination

The screw-dowel combination ensures permanently secure fixation, even under heavy loads and extreme conditions.

Impressive technical data

The technical data demonstrate the performance of the fastening system with examples, although this always depends on external factors and influences. The reference values base on the requirement standard DIN EN 13481-2; other applications are proven and can be provided based on request.
