A classical V-belt is only as good as the number you match it to. This Optibelt VB S=C Plus belt carries the marking 13 x 686 Li, so the fastest way to identify the correct replacement is to read the old belt before it comes off the drive.
On a worn belt, the marking on the back is often the only readable record of what was fitted. Copy it down exactly as it appears, including the profile letter and the length figure, and note the belt's condition at the same time. If the printing has worn away or the belt failed before you could read it, measure the top width and the outside length of the old belt and send those figures instead.
This belt is a classical V-belt in profile A, with a top width of 13 mm, a height of 8 mm, a 40 degree angle and a length of 686 mm. The code 13 x 686 Li states the same profile and length in the marking format used on the belt itself. Its dimensions are what tie it to a specific drive, so confirm them against the old belt rather than against a similar-looking one on a neighboring machine.
Send the part number, the marking from the old belt, or your measurements to MR Industrial Accessories by WhatsApp or email. The team replies promptly and can confirm the correct belt or suggest an equivalent. If a drive runs more than one belt, note how many the drive takes so the whole set can be matched at once.
