The Stark B 51 is a classical V-belt with a B profile. It measures 17 mm across the top, stands 11 mm high, and has a 40° angle. Use these dimensions to match it to the belt you are replacing.
When a belt fails, the fastest way to confirm the replacement is to compare the profile and the size. The B profile is the section that fits the pulley groove; the 17 mm top width, 11 mm height, and 40° angle identify it. If the old belt is worn or the marking is gone, measure across the top of the belt and its height with a caliper, then compare those numbers to the Stark B 51.
The same size is also listed under Mitsuboshi B 51 and Optibelt B 51. If your drive uses more than one belt, replace the full set so the load stays even across the grooves. Inspect the pulleys for wear, alignment, and debris before installing the new belt.
To request a quote, send the part number B 51 and the quantity you need by WhatsApp or email. If you are unsure whether this is the correct belt for your drive, include the old belt's marking or your measurements and the team will confirm it or suggest an equivalent.
