The Optibelt B 33 is a classical V-belt with a B profile and a 914 mm length. If you are replacing a belt on a drive, the most reliable approach is to read the marking on the old belt and match it exactly.
A B profile belt has a 17 mm top width, an 11 mm height and a 40 degree angle. These dimensions matter when the belt runs in a specific pulley groove. The B 33 is also listed under the same size by Stark and Mitsuboshi, so if you find one of those markings on the old belt, it is the same size.
When matching a belt, check the full marking on the back, not just the profile. The B 33 designation covers the cross-section and the length. If the old belt is worn or the marking is unreadable, measure the outside length and compare it to the 914 mm figure. Do not assume a nearby size will fit; a different length changes how the drive tensions and runs.
For a quote, send the part number B 33, the brand Optibelt, and the quantity you need. If you are unsure, send a photo of the old belt marking and the pulley groove. We carry this belt and can confirm it against your application.
