This Optibelt Alpha Flex timing belt is identified by the code 25 T5K6 / 12000 AFX. The T5 profile and 12000 mm length are the two dimensions that matter most when you are matching a belt to a drive. Use them to confirm the belt will fit before you request a quote.
The T5 profile sets the tooth shape and the 5 mm pitch sets the spacing from one tooth to the next. The 12000 mm length is the belt's own dimension, not a range or a cut length. On a long-span drive, those three numbers decide whether the belt runs cleanly on the pulleys or sits wrong from the first turn.
When you replace a timing belt, read the marking on the back of the old belt and compare it with 25 T5K6 / 12000 AFX. If the profile and the length agree, the belt is the one to quote. If the marking is worn or unreadable, measure the old belt and check the tooth profile against the pulley before ordering.
Send the part number 25 T5K6 / 12000 AFX by WhatsApp or email and our team will reply promptly. If you are unsure about the profile or the length, include the old belt's marking and a photo of the drive. We can confirm the right belt or suggest an equivalent.
