This Optibelt VB S=C Plus belt is a classical V-belt with a B profile and a length of 3912 mm. It measures 17 mm across the top, stands 11 mm high and runs at a 40-degree angle. Use these figures to match the belt you are replacing.
The simplest way to confirm a match is to read the marking on the back of the old belt. Look for the profile letter and the length number, then compare them with the B profile and 3912 mm length listed here. If the old belt is worn or the marking is gone, measure the top width and the outside length before ordering.
Because a classical V-belt wears into the groove, a used belt can measure narrower than its original 17 mm top width. That is normal and does not mean the replacement should be a different profile. Confirm the sheave groove is clean and the pulleys are aligned while the belt is off.
If you are unsure whether this B-profile, 3912 mm belt is the correct replacement, send the part number and the marking from the old belt to our team by WhatsApp or email. We will help confirm the right belt for your drive.
