A rubber pulley is a type of pulley that uses a rubber material on its surface to provide traction and increase the gripping force between the pulley and a belt or rope. Rubber pulleys are commonly used in vehicles, industrial machinery, and other applications where mechanical power is transmitted through a rotating system. The rubber material used in the pulley helps to prevent slippage and reduce wear and tear on the belt. The pulley is typically made of a metal or plastic core for durability and is coated with a layer of rubber on the outer surface. Rubber pulleys come in different sizes and shapes to suit different applications and may feature grooves or teeth for better alignment with the belt or rope.
