This occurs when the pulleys are not parallel in the vertical plane — one pulley is tilted up or down compared to the other. This condition causes the belts to enter and exit at an angle, leading to uneven tension, edge wear, and reduced drive performance.
This occurs when the pulleys are on parallel shafts but are not horizontally aligned — one pulley is positioned too far left or right relative to the other. Also known as horizontal offset misalignment or simply just offset misalignment, this causes belts to run off-center, increasing the risk of slippage, uneven loading, and premature belt wear.
This occurs when the pulleys are angled in the horizontal plane — one pulley is rotated slightly compared to the other. This condition creates a “V”-shaped belt path that results in side loading, vibration, and accelerated belt and sheave wear.
For over 25 years, the Belt Hog has been silencing squeals and straightening pulleys with no-nonsense precision. Trusted by maintenance crews across industries, it’s the go-to tool when belt-driven machines need to shape up—or shut up.
Proper belt alignment ensures efficient power transmission, reduces wear on components, and prevents costly unplanned downtime. By aligning belts and pulleys correctly, you extend the life of your equipment and improve overall reliability.
