When a timing belt needs replacing, the marking on the back of the old belt is the fastest way to identify the correct part. This page covers the Optibelt 50 AT5K6 / 1700 AFX, an Alpha Flex timing belt with an AT5 profile, a 1700 mm length and a 5 mm pitch. We supply this belt to maintenance, engineering and purchasing teams across the United States, Canada, Mexico and South America.
Read the old belt before you order. The back of a timing belt carries the profile, length and other identifying characters. On this Optibelt belt, the marking is 50 AT5K6 / 1700 AFX. The profile is AT5, the length is 1700 mm and the pitch is 5 mm. If the printing is worn, check the drive for any documentation that records the belt part number.
The AT5 profile is a synchronous belt profile, so the belt engages pulleys by teeth rather than by friction. The 1700 mm length and 5 mm pitch define the fit on the drive. This is an Optibelt Alpha Flex belt. When you request a quote, send the full marking from the old belt so we can match it to the correct part number.
If you are replacing more than one belt on the same drive, note each marking separately. Belts on a multi-belt drive can wear at different rates, and recording each part number helps keep the next order accurate. Send the part number 50 AT5K6 / 1700 AFX by WhatsApp or email and our team will reply promptly to confirm the belt or suggest an equivalent.
