Example of combinations
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.
