The Optibelt 5-B 2100 is a banded V-belt from the KB VB series, built to keep multiple V-belts running as one unit on drives that need synchronized power transmission. With a 2100 mm length, it is identified by its part number and profile. When replacing a banded belt, matching the existing belt's marking is the first step to a correct fit.
To match this belt to the one being replaced, read the marking on the back of the old belt. Look for the part number, profile, and length. The 5-B 2100 corresponds to a 2100 mm length and the 5-B profile. If the old belt is worn or the marking is unreadable, measure the length along the belt's outer circumference and note the number of ribs or bands.
A banded V-belt ties several V-belts together with a top cover, so they act as a single belt. This construction helps prevent belt whip, flipping, and uneven tension that can occur with individual belts on multi-groove drives. The KB VB series is designed for drives where multiple belts must stay aligned.
When ordering a replacement, provide the complete part number, 5-B 2100, and confirm the profile and length match your old belt. If you need help identifying the correct belt or want to confirm an equivalent, send the marking details and a photo of the old belt to our team via WhatsApp or email. We will reply promptly with the right belt for your drive.

Frequently asked questions
- How do I match the Optibelt 5-B 2100 to my old belt?
- Check the marking on the back of the old belt for the part number, profile, and length. The 5-B 2100 indicates a 5-B profile and a 2100 mm length. If the marking is worn, measure the outer length and count the number of ribs.
- What does banded mean for this V-belt?
- A banded V-belt joins multiple V-belts with a common top cover so they run as one unit. This helps maintain alignment and reduces vibration on drives that use several belts side by side.
- Can you help confirm this is the right belt for my drive?
- Yes. Send the part number from your old belt, the drive details, and a photo if possible via WhatsApp or email. Our team will review and confirm the correct replacement.
