'''Idlers''' are used to take up extra belt length and provide adjustment for tensioning belt drives. | |||
Idler pulleys and sprockets can be valuable belt drive components. Idler pulleys and sprockets can alter belt paths, make the belt clear obstructions, or apply belt pre-tension. Idlers may remain in a fixed location, or may be adjustable to allow belt pre-tensioning and take up. | |||
Idlers may be applied to either the inside or backside of belts. Inside idlers may consist of sprockets, pulleys, sheaves, or flat pulleys. Backside idlers are generally flat. | |||
