OPTIBELT 50 / 5M 4000 AFX belongs to timing belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 50 / 5M 4000 AFX and any equivalents.
The Optibelt 50 / 5M 4000 AFX is an Alpha Flex timing belt with an HTD 5M profile and a 4000 mm length. To match it to the belt being replaced, read the marking on the back of the old belt and compare the profile and length before you request a quote.
The HTD 5M profile identifies the tooth shape and 5 mm pitch. The length is 4000 mm. These two values, together with the part number 50 / 5M 4000 AFX, are what you need to confirm a match. If the old belt is worn or the marking is unreadable, measure the length and check the tooth profile against the replacement.
When you contact us, send the part number 50 / 5M 4000 AFX and, if possible, a photo of the back of the old belt. We carry the Optibelt Alpha Flex line and can help confirm the right belt or suggest an equivalent. For drives that run more than one belt, replace the full set at the same time so the load stays even across the drive.
Before installing, inspect the pulleys for wear, alignment and debris. A worn pulley can damage a new timing belt. After installation, check the tension according to the drive manufacturer's procedure. Keep the old belt as a reference until the new one is running correctly.
