This Optibelt banded V-belt is built for drives where multiple V-belts run side by side and must act as one unit. The SPC KB 4250 measures 4250 mm in length and is used in industrial power transmission. MR Industrial Accessories supplies this belt to maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.
Banded V-belts are common on heavy-duty drives such as crushers, mixers, compressors and large fans, where a single belt would slip or flip under load. The band holds the individual belts together, keeping them aligned in the pulley grooves. The SPC KB 4250 is an Optibelt belt in the KB SK series with a 4250 mm length.
To confirm fit, check the marking on the back of the old belt and match the profile and length. Measure the belt length only if the marking is unreadable. Inspect the pulley grooves for wear, and replace all belts in the drive as a set so the load stays evenly shared.

Frequently asked questions
- How do I confirm the SPC KB 4250 is the right belt for my drive?
- Read the marking on the back of the belt you are replacing. The profile and length must match the SPC KB 4250. If the marking is worn, measure the belt length and check the pulley groove profile before ordering.
- Can I replace only one belt in a banded set?
- No. Banded V-belts are designed to work as a set. Replacing only one belt can cause uneven tension and premature wear. Replace all belts in the drive at the same time.
- What information should I send to request a quote?
- Send the part number SPC KB 4250, the quantity you need, and any details from the old belt marking. If you are unsure about the profile or length, include a photo of the belt and the pulley grooves.
