V Idler Pulley and Vee Drive Sheave Sizes

*2" diameter available only with 10mm bore. Works with 3/8" or 10mm bolt. Uses 6200 bearing -- 9 mm wide. None of our bore adapters will fit this bearing. Not available with drive adapter. All our other V-idlers use the 6203 bearing -- 12 mm wide, 17 mm bore, which fits all our bore adapters.

Our round idler pulleys have tapered flanges that accommodate the V-belts shown below. These include Twin A-section pulleys and Twin 3L-section sheaves (also called Twin-A sheaves and Twin-3L pulleys). Different pulley styles allow V-belts to protrude different heights above the pulleys. If your belts are under such high tension that you fear they may deform and slip deeper into the groove, we can insert round belts in the bottom of the groove that support them and prevent deformation.

These V idler pulleys and V drive pulleys are designed for DuraBelt's urethane and polyester round and V-belts, but they also work well with rubber V-belts and steel cables.

Our Vee idler and Vee drive pulleys/sheaves are made from nylon reinforced fiberglass with and ABEC-1 ball bearings. This nylon material is easy to machine on a lathe, and there is no fiberglass dust, as long as you do not grind it. We can cut down the flanges and/or add grooves (e.g. Poly-Vee grooves) at a slight extra cost.

When ordering by part number, specify either Idler or Drive, but not both.

Our idler pulleys can be converted to drive pulleys with our drive adapters. Click here for V Pulley specs
