.jpg) | Round Idler Pulley • Idler 5/16 x 2.13" has a 6202 bearing -- 11 mm wide. • Available only with .59" (15mm) bore diameter or .35" (8.9mm) bore adapter. • All our other round and flat idlers use the 6203 bearing -- 12 mm wide, which fits all our bore adapters.  | ||||||||
.jpg) | Twin Idler Pulley (Double Sheave) • For 1/8", 3/16", 1/4" and 5/16" belts. • Also used as diverter wheels with 5/16" or 3/8" tires. • 2.25" OD, 1.83" ID, 1.01" width. • Made from high-grade nylon reinforced with fiberglass. • A.B.E.C.-1 6203-2RS bearing (17mm bore). • Available with sealed or low friction shielded bearings. • Bore adapters available for 5/16", 3/8", 10mm & 1/2" bolts or shafts. Although we call it by two different names, we only make one size of twin idler pulley. Customers use this dual sheave with many different belt cross-sections, including 1/8", 3/16", 1/4", 5/16", and even 3/8" belts. When our 83A/85A durometer belts are stretched tight, they are soft enough to conform to the pulley groove. Therefore, the groove radius is not critical. Under normal loads the belts will not slip. | ||||||||
.jpg) | V Idler Pulley and Vee Drive Sheave Sizes • 2" diameter available only with 3/8" (9.5 mm) bolt hole. Uses 6200 bearing -- 9 mm wide. None of our bore adapters will fit this bearing. All our other V-idlers use the 6203 bearing -- 12 mm wide, which fits all our bore adapters. | ||||||||
.jpg) | Flat Idler Pulley and Flat Drive Pulley (Sheave) Sizes These flat idler pulleys and flat drive sheaves are designed for DuraBelt's flat urethane belts, but they also work well with any kind of flat belt. Uses 6203 bearings -- 12 mm wide. Our flat idler pulleys and flat drive sheaves are made from nylon reinforced with fiberglass 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. Our idler pulleys can be converted to drive pulleys with our drive adapters. Maximum bore diameter without an adapter is 17mm (0.669") | ||||||||
