This Optibelt Alpha Power timing belt is identified by the code AT5 420. It uses the AT5 profile with a 5 mm pitch and a 420 mm length. Use it to confirm the exact belt for your drive.
Timing belts in the AT5 profile are common on compact drives where synchronization is required. The 420 mm length and 5 mm pitch define the fit on the pulleys. If you are replacing an existing belt, read the marking on the back of the old belt and match the profile and length before ordering.
To confirm this belt suits your application, check that the drive uses an AT5 profile pulley and that the belt path measures 420 mm. The 5 mm pitch must match the pulley grooves. If the old belt is worn or the marking is unreadable, measure the length along the belt path and compare it to the data here.
