Product Description

This is a Lovejoy variable speed WB series pulley with a 6" outer diameter and one groove. It fits a variety of widely available, variable-speed belts suitable for use in many existing power transmission drives, including conveyors, printing presses, and bottle-filling machines. This pulley has lightweight, aluminum anodized flanges that decrease vibration in the drive which reduces overall noise. It works with both adjustable- and fixed-center drives and is designed for variable-speed applications requiring speed changes. It has one groove for use with single belts. V-belt pulleys (sheaves) are used in a wide range of mechanical and electronic drives, including HVAC units, farm machinery, food processing equipment, and home appliances, among others.

V-belt pulleys (sheaves) are the component in a power transmission drive that transmits power to the belt. Typically made of cast iron, the pulleys and the V-belts that loop around them match in form – wide (classical) or narrow, single or multi-grooved. V-belt pulleys are found in drive designs in the agriculture, textile, printing, mining, and office equipment industries.

Lovejoy manufactures V-belt pulleys and other power transmission products. The company, founded in 1900 and headquartered in Downer’s Grove, IL, provides tools that meet American National Standards Institute (ANSI), Deutsches Institut für Normung (DIN) standards, and others.
