Molaton RailCare-S150070-D Rail Grinding Wheel Product Description
Molaton RailCare-S150070-D: Dual-Step Bore for Zero-Runout Turnout Grinding
The Molaton RailCare-S150070-D a high-precision 150×70mm grinding wheel engineered for direct mounting on Geismar and Robel 150 Model handheld grinders. It features a dual-step bore with outer diameter 20mm, inner diameter 34mm, and step width 18mm, ensuring perfect concentricity (<0.05mm) without flanges or adapters.
This design eliminates vibration and runout during operation, enabling precise edge control on switch points and frogs in demanding field conditions. Reinforced with glass fiber and featuring a 20-grit zirconia-alumina (ZA/A) resin-bond abrasive, the wheel delivers consistent cutting performance and extended service life at 50 m/s.
Ideal for urban rail, metro systems, and maintenance teams requiring accuracy and reliability in turnout repair applications.
