Fraying
Fraying, characterized by the separation and unraveling of the belt’s outer fibers, signifies advanced wear. This often occurs along the edges of the belt due to friction against pulleys or guides. Fraying weakens the belt, reducing its ability to effectively transmit power and increasing the likelihood of complete breakage. Addressing fraying promptly through belt replacement prevents further damage and maintains optimal performance.
-
Glazing
Glazing appears as a smooth, shiny surface on the belt, indicating excessive slippage and heat buildup. This often results from improper tension, worn pulleys, or debris accumulation. A glazed belt loses its grip, reducing power transmission efficiency and accelerating wear. Addressing the underlying cause of glazing, such as adjusting tension or replacing worn pulleys, is essential for restoring proper function and preventing further damage.
-
Missing Pieces/Chunks
Missing pieces or chunks from the belt represent significant damage and indicate imminent failure. This severe wear can result from impacts with foreign objects, severe slippage, or extreme age.
