The Optibelt 16 T20 / 4600 AFX is an Alpha Flex timing belt with a T20 profile, a 4600 mm length and a 20 mm pitch. Before you fit it, inspect the drive and the sheaves so the new belt runs true from the start. We supply this belt to maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.

A timing belt change is the moment to look at the whole drive, not just the belt. Check the sheave grooves for wear, scoring or debris, confirm the sheaves are aligned and securely mounted, and inspect the bearings and tensioner for rough movement. A worn or misaligned sheave will shorten the life of any new belt, regardless of its profile or length.

Confirm the marking on the back of the old belt matches the Optibelt 16 T20 / 4600 AFX: T20 profile, 4600 mm length, 20 mm pitch. If the drive has been modified or the old marking is unreadable, measure the pitch length and count the teeth so the replacement matches the original specification. Replace belts in sets where the drive uses more than one, and recheck tension and alignment after the first run-in.
