This Optibelt Alpha Flex timing belt is identified by the code 100 / H 4250 AFX. It uses the H profile and measures 10795 mm in length. Use these two values to confirm the belt matches your drive before you request a quote.
The H profile defines the tooth shape and pitch that must match your pulleys. The 10795 mm length is the datum you compare against the old belt or the drive specification. If both the profile and the length agree, the belt is the correct size for that position.
The marking on the back of the belt is the quickest way to confirm what you are replacing. Note the full code, including 100 / H 4250 AFX, and check it against the drive documentation. A belt that has lost its marking can still be identified by profile and length.
Send the part number and the quantity you need by WhatsApp or email. If you are unsure about the profile or length, include a photo of the back of the old belt and the pulley details. We carry Optibelt Alpha Flex and can help confirm the right belt or suggest an equivalent.
