This Optibelt SPB 3450 belt is a narrow wedge V-belt in the SK metric profile series. It is used on industrial drives where a compact, high-capacity V-belt is required. Confirm fit by checking the SPB profile and the 3450 mm length against your drive.
The SPB profile is a metric narrow wedge section with a 16.3 mm top width, 13 mm height and 40-degree angle. These dimensions suit drives designed for SPB pulleys, where the belt runs in the groove and transmits power through the wedge action. The 3450 mm length is the datum length for this belt, so the replacement must match both the profile and that length.
To confirm the correct belt, read the marking on the back of the old belt. Look for the SPB profile and the length, then compare it with this Optibelt SPB 3450. If the marking is worn or missing, measure the top width and the outside length of the old belt and check the pulley groove profile. A belt with the wrong profile or length will not sit correctly in the groove and will not deliver the expected service life.
When replacing more than one belt on a multi-belt drive, fit a matched set of the same profile and length. Inspect the pulleys for wear, alignment and groove condition before installation. For a quote, send the part number Optibelt SPB 3450, the quantity and any drive details you have. We carry this belt and can help confirm it or suggest an equivalent.

Frequently asked questions
- What does the SPB profile mean for fit?
- SPB is a metric narrow wedge profile with a 16.3 mm top width, 13 mm height and 40-degree angle. It must match the pulley groove profile. If the old belt is marked SPB and measures 3450 mm, this belt is the correct profile and length.
- How do I confirm the length of this belt?
- The length is 3450 mm. Check the marking on the back of the old belt for the length, or measure the old belt against this figure. The profile and length together determine fit.
- Can I replace just one belt on a multi-belt drive?
- On a drive with multiple belts, replace the full set at the same time with belts of the same profile and length. Mixing new and worn belts can cause uneven load sharing. Inspect the pulleys before installing the new set.
