This Optibelt SPC KB 4000 RP is a banded V-belt from the KB Red Power 3 series. The profile is SPC and the length is 4000 mm. Use these two figures to match the belt to your drive before you request a quote.
The SPC profile sets the cross-section that must seat correctly in the pulley grooves. The 4000 mm length is the datum you compare against the belt you are replacing. Both values are printed in the part number, so a quick check of the old belt's marking confirms the match.
Banded construction ties the ribs together, which suits drives where single belts would whip or turn over. When you replace a banded belt, fit the complete set at the same time so the load stays shared across all ribs. Inspect the pulley grooves for wear before installation.
Send the part number SPC KB 4000 RP by WhatsApp or email and our team will confirm the belt or suggest an equivalent. If the marking on your old belt is worn, send the profile and length, plus a photo of the drive, and we will help identify what you need.
