As the name suggests, these chains are quieter than roller chains.
They may be run at higher speeds, because there is minor impact force when the chain link engages the sprocket. The inverted-tooth chain has a smooth flat surface, which can be conveniently used for conveying. Power capacities of silent chains are listed in tables analogous to those for roller chains. However, these chains reach maximum power at maximum speed, while roller chains reach highest power far below their maximum speed. Most of the remarks in the foregoing paragraphs relate as well to inverted-tooth chains and sprockets, which are also standardized by ANSI [16]. Regular pitches vary between and 2 in. Sprockets may have 21 to 150 teeth. Center distance adjustment is periodically needed to compensate for wear.
