Aerobelt uses air to levitate the belt and form the trough without the use or contact of an idler roller . Air is blown through perforated holes that create a film of air for the belt to float on . Three idler conveying uses multiple angled rollers that the belt passes over to form the trough .

For idler sprockets usually wear at the bottom of the tooth space. When the tooth space is worn deeply enough, the chain rollers may bind against the tooth tops as they enter and leave the idler sprocket. The sprocket wear can be source of shock loads in the chain. Reversing the sprocket on the shaft can sometimes extend the life of worn sprocket.
