This is the Optibelt SPB KB 4000 RP, a banded V-belt from the KB Red Power 3 series with a 4000 mm length. The SPB profile and the 4000 mm length are the two figures to check first, because they decide whether the belt fits your drive or not.
A banded V-belt ties several V-belts together into one unit, so the ribs run as a single assembly over the pulleys. That construction suits drives where you want the load shared across the ribs and the belt to stay in line rather than roll or flip. The SPB profile sets the cross-section and the groove it seats in; the 4000 mm length sets the wrap around your pulleys. Both values have to match the drive before anything else is considered.
To confirm a replacement, read the marking on the back of the belt you are taking off and compare it with SPB KB 4000 RP. Check the profile, the length and the number of ribs against the drive, and look over the pulleys and tensioner while the belt is off. If the belt has run as part of a set, replace the set together so the ribs carry the load evenly.
