The Optibelt A 21 is a classical V-belt with an A profile and a 584 mm length. This page covers how to confirm it matches your drive by reading the marking on the old belt.
Start with the marking on the back of the belt you are replacing. The Optibelt A 21 carries the code A 21, which identifies the profile and the length. The belt has a top width of 13 mm, a height of 8 mm, and a 40-degree angle. If the marking on your old belt reads A 21, this is the belt to specify.
If the marking is worn away, measure the belt and match the dimensions. The same size is also listed under Mitsuboshi A 21 and Stark A 21. Send the part number, the application, and a photo of the old belt marking to our team by WhatsApp or email, and we will confirm the correct belt or suggest an equivalent.
