The Stark A 123 is a classical V-belt with an A profile. It measures 13 mm across the top, 8 mm in height, and has a 40° angle. To match it to the belt being replaced, read the marking on the old belt and confirm the profile and dimensions.
Start by locating the part number on the back of the belt you are replacing. If it reads A 123, this Stark belt matches that callout. Check the top width and height with a caliper: 13 mm top width and 8 mm height are the defining dimensions for the A profile. The 40° angle is the standard wedge angle for this profile.
If the old marking is worn or missing, measure the top width and height directly. An A profile belt will measure 13 mm across the top and 8 mm in height. The same size is also listed under Mitsuboshi A 123 and Gates A 123, so you can compare those markings if you find them on the old belt.
When you request a quote, send the part number A 123 and the profile A. If you have the old belt, include the marking and the measured top width and height. Our team can confirm the right belt or suggest an equivalent from the brands we carry.
