The Optibelt A 31 is a classical V-belt with an A profile and an 838 mm length. It measures 13 mm across the top, 8 mm in height and has a 40° angle. This page helps you match it to the belt you are replacing.
To confirm the A 31 is the correct replacement, read the marking on the back of the old belt. Look for the profile letter A and the length number 31. If the old belt is too worn to read, measure its top width and height and compare them with the 13 mm and 8 mm dimensions above. The 40° angle is the standard V shape for this profile.
The same size is also listed under Stark A 31. If you need to verify fitment or discuss an equivalent, send the part number and the application details by WhatsApp or email. Our team replies promptly and can help confirm the right belt for your drive.
