    Note) The roller diameter (Da) for model numbers containing symbol V at the end represents the value 1/√2 times that of types for the same model number with no symbol. The diameter of the roller to be combined with 90°V surface will be 1/√2 times that of the roller on the flat surface. For example, when using model FT4035 (roller diameter: Ø4) on the flat surface, use model FTW4030V (roller diameter: Ø2.828) on the V surface. Performance of the Flat Roller is significantly affected by the contact state of the upper and lower raceways. You can check the fit before installing the Flat Roller by designing the raceways as indicated in the figure above.
