The Optibelt D 420 KB is a banded V-belt from the KB series. This page helps you match it to the belt you are replacing.
When replacing a banded V-belt, start with the marking on the old belt. Confirm the profile and the length before ordering. The D 420 KB is a banded V-belt in the D profile with a length of 420 mm.
Banded V-belts join multiple V-belts into one unit. They are used where several belts run in parallel and must stay aligned. The D profile is a heavy-duty cross-section. The 420 mm length is the datum length for this belt.
If the old belt is worn or the marking is unreadable, measure the length and check the profile. Send the part number, D 420 KB, or the old belt details. We will confirm the match.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Check the marking on the belt you are replacing. It should show the profile and length. The D 420 KB is a D-profile banded V-belt with a 420 mm length. If the marking matches, it is the correct replacement.
- What if the marking on my old belt is worn off?
- Measure the outside length and the top width of the belt. Also count the number of ribs if it is a banded belt. Send those details along with a photo if possible. We will help identify the correct belt.
- Can I replace just one belt in a banded set?
- Banded V-belts are designed to be replaced as a complete unit. Replacing only one belt can cause uneven tension and premature failure. Always replace the full banded belt.
