Key Features

  • Narrow V-belt sheave fits narrow profile V-belts for increased drive efficiency over classical V-belts

Product Description

This Martin Hi-Cap QD sheave with a 3V belt section is made of 30 gray cast iron and comes with two grooves. It is a narrow V-belt sheave that fits narrow profile V-belts , allowing the use of smaller or fewer belts than classical V-belts to transmit an equivalent load, maximizing power transmission efficiency by reducing drive weight and size. This pulley is made of class 30 gray cast iron for resistance to wear, corrosion, and galling. It has a 3V cross section and two grooves for use with multiple or banded 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.

Martin Sprocket & Gear manufactures power transmission and conveying products. The company, founded in 1951 and headquartered in Arlington, TX, provides tools that meet American National Standards Institute (ANSI), National Aerospace Standard (NAS), and Deutsches Institut für Normung (DIN) standards.
