The Optibelt 50 T20 / 8400 AFX is an Alpha Flex timing belt with a T20 profile, an 8400 mm length and a 20 mm pitch. When you are replacing a belt on a driven system, matching the marking on the old belt is the first step. This page covers the details to confirm before you request a quote.
Start by reading the back of the belt you are replacing. The part number, profile and length printed there are what you compare against this Optibelt 50 T20 / 8400 AFX. A T20 profile with an 8400 mm length and a 20 mm pitch is a specific combination; if your old belt shows different values in any of those fields, send us the full marking so we can help confirm the right belt or suggest an equivalent.
If the marking is worn or unreadable, check the drive documentation or measure the old belt. The profile and pitch must match the pulleys, and the length must suit the center distance. Do not rely on a partial number alone. Send the part number you found, along with the profile, length and pitch if you have them.
We carry the Optibelt 50 T20 / 8400 AFX for maintenance, engineering and purchasing teams. To request a quote, send the part number by WhatsApp or email. If you are unsure whether this is the correct belt, include the old belt marking, the profile, length and pitch, and any other details from the drive. The team replies promptly and can help confirm the right belt or suggest an equivalent.
