The Optibelt 4-A 2845 is a banded V-belt from the KB VB series, built for drives that need multiple V-belts to work as a single unit. Banded construction keeps the ribs aligned and reduces the vibration and whip that can occur when separate belts run side by side. This belt is identified by its 2845 mm length.
Banded V-belts are commonly used on heavy-duty industrial drives where two or more V-belts share the load, such as large fans, crushers, mixers and process equipment. Because the ribs are joined by a top band, the belt tracks as one piece and helps keep the set from turning over in the groove or jumping off under shock loads. If your drive calls for a banded belt, replacing it with loose single belts is not the same fix.
To confirm fit, read the marking on the back of the old belt and match the part number 4-A 2845, then measure the outside length to verify 2845 mm. Check the pulley grooves for wear, alignment and any debris before installing a new belt. When you request a quote, send the part number, the number of ribs in the band, and a photo of the belt marking if you have one.

Frequently asked questions
- How do I confirm that the Optibelt 4-A 2845 is the right belt for my drive?
- Compare the part number on the back of your existing belt with 4-A 2845 and check that the length matches 2845 mm. Also confirm the number of ribs in the band and the profile against your pulley grooves.
- Can I replace a banded V-belt with individual V-belts?
- A banded belt is designed to run as a set joined by a top band. Replacing it with individual belts can lead to uneven tension, belt whip and turnover in the groove, so it is best to use the banded type specified for the drive.
- What should I send to get a quote for the 4-A 2845?
- Send the part number 4-A 2845, the quantity you need, and a photo of the belt marking if possible. If you are unsure of the profile or length, include the drive details and our team can help confirm the correct belt.
