Fan belt is the traditional term for what today is called a drive belt. Drive belts are made of reinforced, high-tensile strength cords and synthetic rubber. Belts come in two different types: The traditional V-belt (cross-section of belts has a V-shape for V-shaped pulleys) and the serpentine belt (also called Poly-V, Poly-Rib, Multi-Rib, and Micro-V belt), which uses multiple Vs for more positive contact with its matching pulleys.
Applications for drive belts: provide power to engine-mounted accessories like air compressor, automobile engine, exhaust fan, and pumps.
The V-Belts "L" series are excellant for light industrial applications such as appliances, and power equipment that require the tough, long wearing, trouble free belts. Ideal for any light duty fractional horsepower drives including backside idler applications.
The belt cover is oil, heat and ozone resistant in order to protect the inner components.
Suggestions: Properly tighten. Check V-belts, a slipping belt usually has shiny sidewalls (glazing) caused by heat from sliding in the pulleys. The glazing often causes a chattering, slapping or squealing noise. Glazing hardens the belt making them prone to cracking and early failure. Belt slippage often occurs because of low tension, the wrong belt for the job, grease, oil or dirt build-up. A V-belt with these conditions should be replaced as soon as possible. Serpentine belts, inspect the belt closely for any cracks in the ribbed area. Also check the backside of the belt for grooves, fraying, or splitting.
