  • The guide flange that will be discontinued can be secured to the side of the return roller, but alternative products cannot.
  • When replacing a discontinued model with an alternative model, the roller width will be 3.5 mm shorter, so the lateral clearance will be larger. The inner diameter is also 1mm larger, but it can be used without any changes to the existing shaft.
