This Optibelt 25 / 5M 3400 AFX belt is an HTD 5M timing belt from the Alpha Flex series. The profile and the 3400 mm length are the two numbers that decide whether it fits your drive, so start there. If you already have the old belt in hand, the marking on the back is the fastest way to confirm the match.
The 5M profile is an HTD tooth form with a 5 mm pitch. The 3400 mm length is the datum length for this belt. A timing belt only works when the tooth profile, the pitch and the length all agree with the pulleys on the drive, so check all three against the belt you are replacing.
If the old belt is worn or the marking has rubbed off, send us the part number you have and a photo of the back of the belt if you can. We can help confirm the right belt or suggest an equivalent. We carry Optibelt belts and serve maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.
When you request a quote, include the part number 25 / 5M 3400 AFX and the quantity you need. If you are unsure whether this is the correct belt for your application, tell us the drive details and we will check it against the data we have.
