Engineered for extreme-load automation, our wheel-on-hard-rail systems deliver uncompromised stability and precision where conventional linear guides fail. Featuring induction-hardened steel rails (HRC 60+) and preload-adjustable V-groove wheels, this solution achieves ±0.003mm/m straightness accuracy under 25-ton loads – redefining performance standards for gantry cranes, automated forging cells, and heavy-payload transfer systems.
The four-point contact geometry creates mechanical preload independent of lubrication, distributing loads across dual raceways to eliminate micro-deflection. Proprietary carbide-coated wheel treads reduce rolling resistance by 40% while withstanding 200 million passes in abrasive environments like foundries or mining operations. Modular rail segments with laser-aligned joints enable seamless 100m+ travel with cumulative error <0.1mm.
