Aluminoline variable speed pulleys are designed for the best possible belt alignment with the least amount of overhung load. Flanges are made of a lightweight, corrosion-resistant aluminum, which is hard-coat anodized for long life. The aluminum flanges provide quiet operation with minimum vibration. These pulleys are used with classical A and B drive belts. Aluminoline pulleys offer maximum service when lubricated through a convenient grease fitting located on the end of the pulley shaft.
Belt Selection: Aluminoline variable speed pulleys are designed to drive standard A and B section belts. Due to the intermeshing flange design, it is best to use a wrapped belt or one without cogs.
Adjustable Center Drives: The typical adjustable center drive consists of the Aluminoline pulley mounted on the motor shaft, a companion sheave on the driven shaft, an adjustable motor base and a belt. Standard A and B fixed diameter sheaves should be used as driven companion sheaves. Belt alignment will be maintained throughout the speed range because the Aluminoline pulleys are two-side moveable. Due to the minimal bottom contact area of A and B belts, flat driven sheaves are NOT recommended.
