Description
OPTIBELT 100 / 5M 3400 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 / 5M 3400 AFX and any equivalents.
The Optibelt 100 / 5M 3400 AFX is an Alpha Flex timing belt with an HTD 5M profile, a 3400 mm length and a 5 mm pitch. When you are replacing a belt, the marking on the back of the old belt is the first thing to check against these three values.
Match the profile first. The HTD 5M profile and the 5 mm pitch identify the tooth form and spacing, so a belt with a different profile will not seat correctly in the pulleys even if it looks similar. Then confirm the length: this belt is listed at 3400 mm. The part number 100 / 5M 3400 AFX combines the profile and the length, which makes it straightforward to compare with the belt you are removing.
If the old belt is worn, stretched or its marking is no longer readable, send us the part number you have and any remaining details from the belt back. We carry Optibelt Alpha Flex timing belts and can help confirm whether this 100 / 5M 3400 AFX is the right match or suggest an equivalent. For a quote, message us on WhatsApp or email with the part number and the quantity you need.
