The Optibelt VB S=C Plus is a classical V-belt with profile E and a length of 4000 mm. We carry this belt for maintenance and replacement work on industrial drives. Before you fit it, inspect the drive and sheaves so the new belt runs true and lasts.
Check sheave grooves for wear, rust, or buildup that can chew a new belt. Confirm the sheaves are aligned and the grooves match the E profile. Spin the sheaves by hand and feel for bearing play or rough spots. If you find problems, correct them before installing the belt.
Measure the old belt and compare it to the 4000 mm length. Look for cracks, glazing, or missing cords. If the drive uses multiple belts, replace them as a set so they share the load evenly. Keep the sheaves clean and free of oil or debris.
To request a quote, send the part number 40 x 4000 Li, the Optibelt VB S=C Plus series, and the profile E. If you are unsure, send a photo of the belt marking and the sheave dimensions. Our team will confirm the right belt for your drive.

Frequently asked questions
- What should I check on the drive before fitting this belt?
- Inspect the sheave grooves for wear, rust, or debris, and verify alignment. Check bearings for play and make sure the grooves match the E profile. Correct any issues before installing the belt.
- How do I identify the belt I need?
- Look for the marking on the back of the old belt. This belt is an Optibelt VB S=C Plus, profile E, with a length of 4000 mm. If the marking is unclear, send us a photo and the sheave dimensions.
- Can I replace just one belt on a multi-belt drive?
- On drives that use multiple belts, replace the full set at the same time. A new belt mixed with old ones can run at a different tension and wear faster.
