When you read the back of an old belt, look for the complete code: B 133 KB and the length 3454 mm. The B profile and the KB series indicate a banded V-belt construction. Banded V-belts join multiple V-belts into one unit, which keeps the belts aligned and reduces vibration in multi-groove drives. The 3454 mm length is the datum length for this belt.
If the marking is worn or faded, measure the belt's length and note the profile and number of ribs. Send the part number, the length, and a photo of the marking if possible. Our team can confirm the right belt for your drive. We carry Optibelt belts and serve maintenance, engineering and purchasing professionals across the United States, Canada, Mexico and South America.
