The Stark B 123 is a classical V-belt with a B profile. It measures 17 mm across the top, 11 mm high, and has a 40° angle. To match it to the belt being replaced, read the marking on the back of the old belt and confirm the same profile and part number.
A B-profile classical V-belt is often identified by the number molded on its back. If the old belt is worn or the marking is gone, measure the top width and height with a caliper and compare them to 17 mm and 11 mm. The 40° angle is the standard included angle for this profile.
The same size is also listed under Gates B 123 and Optibelt B 123. If you need help confirming the right belt or an equivalent, send the part number and the dimensions you measured to our team by WhatsApp or email.
Replacing a classical V-belt is also a good time to inspect the drive. Check sheave grooves for wear, confirm alignment, and look for oil or debris that can shorten belt life. When a drive uses multiple belts, replace the full set so the load stays evenly shared.
