Idlers pulleys use 6203 bearings -- 12 mm wide, 17 mm bore.
Pulleys are made from nylon reinforced with fiberglass (glass filled nylon).
Idler pulleys use ABEC-1 ball bearings. Click here for Pulley specs.
When ordering by part number, specify either Poly-V Idler or Poly-V Drive, but not both.
All idler pulleys can be converted to drive pulleys with our drive adapters.
Maximum bore diameter: idler pulleys = 17mm (0.669"), drive pulleys = 25.4mm (1")
For the best in Poly-V (Micro-V, Multi-ribbed) idler sheaves and Poly-V (Micro-V, Multi-rib) drive pulleys, insist on DuraBelt.
