Idler Pulleys VS Drive Pulleys
Idler pulleys are mechanical components used in belt-driven power transmission systems to guide, support, or tension the belt. Unlike drive pulleys, they do not transmit power — instead, they help maintain proper belt alignment and tension, ensuring smooth and efficient operation of the system.
