I want to know if these are compatible or fit together.

  2. Makeblock Timing Belt MXL 123
  3. 5mm. Aluminum Timing Pulley
  4. MXL 60 Tooth Timing Pulley
  5. 50 mm Aluminum Wheel 4mm bore . Qyt 2 Do these wheels have rubber in the contact area?
  6. 12 inch long shaft. To fit the two 50 mm wheels and the MXL 60 tooth timing wheel
    Are these timing wheels compatible along with the belt?
