The Optibelt AT5 390 is an Alpha Power timing belt with an AT5 profile, a 390 mm length and a 5 mm pitch. Before you fit a replacement, inspect the drive and the sheaves so the new belt runs true and wears evenly.
Check the sheaves for worn grooves, burrs, corrosion or debris, and confirm they are aligned and secure. A sheave that is damaged or out of alignment will shorten the life of any timing belt, including this AT5 390. Verify that the belt path is clear and that all pulleys turn freely.
Confirm the drive takes an AT5 profile and a 390 mm length before ordering. The Optibelt AT5 390 is a timing belt with a 5 mm pitch, and the marking on the back of the old belt is the surest way to match it. If you need help confirming the profile or length, send the belt marking and your equipment details for a quote.
