Laser Fan Pulley Alignment Kit A simple guide for measuring V-belts Ordering the correct replacement belt is as easy as taking a few simple measurements. Much of the equipment in use around today’s confinement systems use some type of rubber drive belts or V-belts. For example, replacing the V-belts on fans every year is just a smart investment as worn belts can reduce performance by as much as 20%. First, to determine what type of belt is on your fan, measure the width of the belt. Most fan belts are A-type belts with a measurement of 1/2”. If the fan belt measures 5/8”, it is classified as a B-type belt. You may see a belt described as type AX. The X means it has a cogged design or notches in the belt. The cogged profile increases the power transfer and is typically used only for industrial applications because of its higher cost. Next, you need to measure the length of the belt. Use a cloth measuring tape (not a steel one) and wrap it around the outside of the belt. You also use a thin string to take this measurement and place it on a steel tape to get the correct length. Next, for “A” Belts (1/2” width), subtract two inches from the outside measurement to select the correct V-belt. For example, if the outer measurement is 48-inches and you subtract two inches, then HSA46 would be the right belt for your fan. For “B” Belts (5/8” width), subtract 3” from the outside measurement to select the correct V-Belt. For example, if the outer measurement is 48-inches and you subtract three inches, HSB45 would be the right belt for your fan. Hog Slat’s line of GroBelts offers producers top-quality V-belts at a great price. GroBelts feature wear-resistant, high modulus compression rubber embedded with polyester cords to reduce stretch.
