Frequently Asked Questions
Which machines does this wheel fit?
It is matched to Vossloh HSG-2 high-speed grinding trains. Please confirm the flange interface or bore against your machine manual before ordering, because the same overall dimensions do not always mean the same wheel.

50 m/s. Always follow your machine manual and never exceed the speed marked on the wheel.
Is this a standard size, and is it in stock?
Yes. This is a standard production size and is held in stock for immediate dispatch. Custom bores, grades and dimensions are produced to drawing, typically in 15 to 30 days.
Which rail defects does this wheel remove?
Corrugation, spalling, shelling, rail head fatigue and gauge corner wear, plus profile restoration in both corrective and preventive grinding passes.
