This Optibelt A 120 belt is a classical V-belt from the VB / Red Power series. The A profile and 3099 mm length are the two figures that matter when you are matching a drive, so start there.
The A profile gives a 13 mm top width, 8 mm height and a 40 degree angle. That is the standard A cross-section, so it seats in an A groove. The 3099 mm length is the datum you compare against the old belt or the drive drawing before you order.
The same size is also listed under Mitsuboshi as A 120. If your line is set up on one of those brands, this is the equivalent size to reference when you send your request.
Send the part number A 120, the Optibelt brand and the length you measured. If you are unsure whether the A profile is correct for the pulley, include a photo of the marking on the back of the old belt with your message.
