When you need to replace a timing belt, the marking on the back of the old belt is the fastest way to identify the correct part. This page covers the Optibelt 15 / 5M 6600 AFX from the Alpha Flex series, a timing belt with an HTD 5M profile, a 6600 mm length and a 5 mm pitch. We carry this belt and can help you confirm it matches your drive before you order.
Start by reading the old belt. Look for a code like 15 / 5M 6600 AFX on the back. The 5M tells you the profile is HTD 5M, the 6600 gives the length in millimeters, and the 15 indicates the belt width in millimeters. The 5 mm pitch is the distance between tooth centers. If the marking is worn or unreadable, measure the length and count the teeth to confirm the profile.
This Optibelt Alpha Flex belt is a timing belt, also called a synchronous belt. It is used where exact synchronization between shafts is required. The HTD 5M profile is a curvilinear tooth form. The 6600 mm length and 5 mm pitch are fixed dimensions, so any replacement must match them exactly.
Send us the full marking from your old belt, along with the equipment make and model if you have it. Our team will confirm the Optibelt 15 / 5M 6600 AFX or suggest an equivalent. You can reach us by WhatsApp or email for a quote.
