Buying advice

Consider the belt or chain type (V-belt, synchronous, roller chain) and required tension range. For heavy-duty or continuous use, invest in automatic or sealed-bearing tensioners. For occasional or light-duty, budget options suffice. Always verify compatibility with your pulley/sprocket size.
