Econoline Series Variable Speed Drive Pulleys w/ Keyway - Imperial

(91) One-Side Moveable
1/3 Through 5 HP, “A” and “B” Belts

The Econoline Pulley series provides reliable variable speed service with a proven design at an economical cost. The wide selection of models feature compact size and reliability, which make them ideal for both adjustable and fixed center drives in all types of applications using classical “A” and “B” (or 4L and 5L) section drive belts.

Spring-loaded pulleys are through-bored for all types of shaft mounting arrangements. The exposed spring design allows for a cooler running pulley and permits easy cleaning. Complete spring enclosures are available as an option on some models. Belt Selection

Econoline pulleys are designed specifically for “A” and “B” section drive belts, though they can also be used with “4L” and “5L” belts if necessary. Cogged, raw-edge belts have a definite advantage over wrapped types because they readily form around small pitch diameters, and provide a better arc of contact and provide best possible transmission of torque. If a “slip clutching” effect is desirable to protect machinery in the event of overload, a wrapped belt is recommended. Adjustable Center Drives
