When replacing an Optibelt 25 AT10K13 / 8200 AFX, the most reliable approach is to match the belt you are removing. This timing belt is part of the Optibelt Alpha Flex series and carries the AT10 profile with an 8200 mm length and 10 mm pitch. Confirm those three details against the old belt before you request a quote.

Start by reading the marking on the back of the belt. You are looking for the part number 25 AT10K13 / 8200 AFX, or at minimum the profile AT10, the length 8200 mm and the pitch 10 mm. If the old belt is worn, dirty or the print is faint, check the drive documentation or the machine data plate for the same figures. A belt that matches on all three points is the correct starting point for a replacement.

Profile and length are the two dimensions that determine fit. The AT10 profile describes the tooth shape, while 8200 mm is the length and 10 mm is the pitch. Do not substitute a different profile or length unless you have confirmed the drive is designed for it. If you are unsure, send the full part number and a photo of the old belt marking to our team; we can help confirm the right belt or suggest an equivalent.

For drives that run more than one belt, replace them as a set so the load is shared evenly. Inspect the pulleys and tensioner at the same time for wear, alignment and correct tension. The Optibelt 25 AT10K13 / 8200 AFX is a timing belt, so it must be installed with the correct tooth engagement and tension to run properly. Note the belt's direction of travel if the old belt shows one, and follow the drive manufacturer's tensioning procedure.
