The Optibelt 1120 8MDC 21 is a Delta Chain polyurethane timing belt with a length of 1120 mm. When you need to replace a belt on a drive, the part number on the old belt is the fastest way to confirm what you need. We carry this belt and quote it by part number.
Start by reading the marking on the back of the belt you are replacing. If it shows 1120 8MDC 21, this Optibelt Delta Chain belt matches that marking. The 1120 mm length is the datum you compare against the old belt; if the old belt is worn or the marking is unreadable, measure the old belt and note the profile and length before requesting a quote.
Send us the part number 1120 8MDC 21, or the profile and length from the old belt, by WhatsApp or email. Our team can confirm the belt or suggest an equivalent. For drives using more than one belt, replace all belts in the set at the same time so the load is shared evenly. Inspect the pulleys and tensioner while the belt is off, and correct any misalignment or wear before installing the new belt.

Frequently asked questions
- How do I match this belt to the one I am replacing?
- Check the marking on the back of the old belt. If it reads 1120 8MDC 21, this Optibelt Delta Chain belt is the match. If the marking is worn, measure the old belt and note the profile and length, then send those details for confirmation.
- What information do you need for a quote?
- Send the part number 1120 8MDC 21, or the profile and length from the old belt, by WhatsApp or email. If you have a photo of the old belt marking, that also helps us confirm the correct item.
