Idlers maintain consistent tension on belts to reduce slippage and move belts away from obstacles. Timing belt pulleys have grooves that provide maximum surface contact with the belt teeth for good power transmission and minimal slipping. V-belt pulleys provide maximum friction and torque in compatible V-belt drive systems.
