Description
OPTIBELT SPB 4750 BP belongs to v-belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for SPB 4750 BP and any equivalents.
The Optibelt SPB 4750 BP is a narrow wedge V-belt in the Blue Power series. It has an SPB profile, a 4750 mm length, a 16.3 mm top width, a 13 mm height and a 40 degree angle. Use these dimensions to match it to the belt being replaced.
Matching starts with the marking on the old belt. Confirm the profile is SPB and the length is 4750 mm, then check the top width of 16.3 mm and the height of 13 mm against the worn belt or the drive drawing. The 40 degree angle is part of the profile geometry and should agree with the pulley groove.
If the old belt is unmarked or the printing has worn off, measure the outside length and the cross section. A belt that is close in length but different in profile will not sit correctly in the groove. Send the part number, the profile and the measured dimensions so we can confirm the SPB 4750 BP or suggest an equivalent.
For drives with multiple belts, replace the full set at the same time so the load stays evenly distributed. Inspect the pulleys for wear, alignment and debris before installation, and check the tension after the first run-in period.

Frequently asked questions
- How do I confirm this is the right belt for my drive?
- Check the old belt for the SPB profile and 4750 mm length, then compare the 16.3 mm top width and 13 mm height. If the marking is gone, measure the cross section and outside length.
- What should I send to request a quote?
- Send the part number SPB 4750 BP, the profile SPB and the 4750 mm length. If you are unsure, include the dimensions from the old belt or the drive drawing.
- Should I replace all belts on the drive at once?
- Yes. On a multi-belt drive, install a complete set so each belt carries its share of the load. Mixing a new belt with worn belts can cause uneven tension and premature failure.
