This Optibelt SPB KB 4250 is a banded V-belt in the KB SK series, with a length of 4250 mm. Banded V-belts are used on drives where several V-belts run side by side and must stay in matched alignment, such as multi-groove industrial drives. Confirm fit by matching the profile, the length and the part number on the belt.
On a banded V-belt, the ribs are tied together by a top band so the belt runs as one unit across all sheave grooves. That construction suits drives that carry pulsating or shock loads, where single belts could whip, flip or wear unevenly. If your drive uses a set of V-belts on one sheave set, this is the type of belt to check.
To confirm this belt fits your drive, read the marking on the back of the old belt and compare the profile and the length. The profile here is SPB, and the length is 4250 mm. Also check the number of ribs and the sheave groove count, since a banded belt must match the groove pattern of the pulleys.
When you request a quote, send the part number SPB KB 4250 and, if you have it, a photo of the belt marking and the drive nameplate. The team can help confirm the right belt or suggest an equivalent. For drives running more than one belt, replace the full set at the same time so the load stays shared evenly.

- Read the marking on the back of the old belt and compare the profile and length, then check that the number of ribs matches the sheave groove count. If you are unsure, send the part number and a photo of the belt marking for confirmation.
