The Optibelt VB S=C Plus 17 x 850 Li is a classical V-belt with a B profile. It measures 850 mm in length, 17 mm across the top, 11 mm in height, and has a 40-degree angle. Use the marking on the belt you are replacing to confirm this is the correct size.
The simplest way to match a replacement is to read the old belt. Look for the profile letter and the length number on the back. This belt carries a B profile and an 850 mm length, so if your old belt is marked the same way, it is the same size. The 17 mm top width, 11 mm height, and 40-degree angle are the dimensions that define the profile.
When the old marking is worn or missing, measure the belt with it laid flat. Check the top width and the outside length, then compare those numbers to the profile and length above. If the dimensions line up, the belt will sit correctly in the pulley grooves.
Send the part number, 17 x 850 Li, by WhatsApp or email to request a quote. If you are unsure whether this is the right belt, include a photo of the old marking and the pulley groove width, and the team can help confirm the match.
