This Optibelt VB S=C Plus belt is a classical V-belt with a B profile and a length of 3950 mm. The marking 17 x 3950 Li gives you the top width and the length you need to match before you order.
For a maintenance or purchasing professional, the two numbers that matter most on this belt are the profile and the length. The B profile is a classical V-belt cross-section, and the 17 mm top width and 11 mm height define the groove it fits. The 3950 mm length is the datum you compare against the old belt or the drive specification.
The 40-degree angle is part of the profile geometry, so the belt seats correctly in a matched B-section pulley. When you request a quote, send the full part number 17 x 3950 Li along with the Optibelt series VB S=C Plus. If you are replacing a belt that has worn or lost its marking, measure the top width and the outside length and include those values.
We carry the Optibelt VB S=C Plus line and quote by part number through WhatsApp or email. If you need help confirming that this B-profile, 3950 mm belt is the right one for your drive, send a photo of the old belt and the pulley groove dimensions with your request.
