Description
OPTIBELT 100 AT5 / 8400 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 100 AT5 / 8400 AFX and any equivalents.
The Optibelt 100 AT5 / 8400 AFX is an Alpha Flex timing belt with an AT5 profile, an 8400 mm length and a 5 mm pitch. When you are replacing a belt, match these three values to the belt you are removing. We carry this belt and quote it by part number.
Start by reading the marking on the back of the old belt. The profile must read AT5, the length must be 8400 mm, and the pitch must be 5 mm. If the marking is worn or unreadable, measure the length along the belt and confirm the profile and pitch against the pulley grooves before ordering.
The 100 AT5 / 8400 AFX is a timing belt, so it is used where teeth mesh with pulleys to keep a drive synchronized. Confirm that the replacement belt matches the original in profile, length and pitch. A belt with the same length but a different profile will not seat correctly in the pulley grooves.
To request a quote, send the part number 100 AT5 / 8400 AFX by WhatsApp or email. If you are unsure whether this is the right belt, send a photo of the back marking along with the profile, length and pitch you measured. Our team can confirm the belt or suggest an equivalent.
