This Optibelt VB S=C Plus belt is a classical V-belt with an 8 profile and a 490 mm length. The marking 8 x 490 Li identifies both the cross-section and the datum length, so you can match it directly against the belt on your drive.
Profile 8 sets the belt's cross-section, which determines how it sits in the pulley groove and how much power it can transmit. Length 490 mm is the datum length used for drive setup. When you read a belt back, confirm both numbers rather than relying on the profile alone, since two belts can share a profile and differ in length.
For a quote, send the full marking 8 x 490 Li, the brand Optibelt and the series VB S=C Plus, plus the quantity you need. If the old belt is worn or the marking is unreadable, measure the outside circumference and the top width, and note the drive it runs on. We carry this belt and can confirm it against your application.
Inspect the drive before fitting a replacement: check pulley grooves for wear, confirm alignment, and set tension to the drive manufacturer's specification. On multi-belt drives, replace all belts in the set at the same time so the load stays even across the grooves.

Frequently asked questions
- What do the profile and length mean on this Optibelt belt?
- The 8 is the profile, which fixes the cross-section, and 490 mm is the datum length. Together they define the belt's fit and running length on the drive.
- How do I confirm this is the right belt for my drive?
- Read the marking on the back of the old belt. If it shows 8 x 490 Li, this Optibelt VB S=C Plus belt matches that profile and length. If the marking is gone, measure the outside circumference and top width and send those with the drive details.
- What should I send to request a quote?
- Send the part number 8 x 490 Li, the brand Optibelt, the series VB S=C Plus, and the quantity. If you are replacing a set, include the number of belts on the drive.
