Description
OPTIBELT 75 AT20 / 4600 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 75 AT20 / 4600 AFX and any equivalents.
The Optibelt Alpha Flex timing belt with part number 75 AT20 / 4600 AFX is identified by three markings on the back of the belt: the profile, the length and the part number. Reading those markings from your old belt is the fastest way to confirm you are ordering the correct synchronous belt. We carry this belt and quote it by part number.
This is an AT20 profile timing belt with a length of 4600 mm and a pitch of 20 mm. The AT20 profile and the 4600 mm length are the two dimensions that must match your drive. If the back of the old belt is worn or dirty, clean it and read the full marking before you request a quote.
When you send your request, include the complete part number 75 AT20 / 4600 AFX along with the profile and length you read from the belt. If the marking is partly illegible, send a photo of the back of the belt and the drive. Our team can help confirm the right belt or suggest an equivalent.
For maintenance and engineering teams, replacing a timing belt with the same profile and length keeps the drive matched to the original specification. Use the marking on the old belt as your primary reference, and treat any other numbers on the belt as secondary.
