The Gates Polyflex JB is a narrow V-belt built for compact, high-speed drives where standard V-belts are too bulky. This listing covers the 5M 387 JB, a 387 mm belt in the Polyflex JB series. Use it as a reference when you need to confirm the right belt for a tight, space-limited drive.
Polyflex JB belts are commonly found on small industrial equipment, machine tools, and appliances where the pulley diameter is small and the drive runs fast. If you are replacing a worn belt, check the profile and the length against the drive before ordering. The 5M profile and 387 mm length are the key dimensions to match.
The easiest way to confirm fit is to read the marking on the back of the old belt. If it shows 5M 387 JB, this is the same belt. If the marking is worn or missing, measure the outside length and compare it to 387 mm, and check that the pulley grooves accept the 5M profile. When in doubt, send a photo of the old belt and the drive pulleys.
We supply the Gates Polyflex JB 5M 387 JB to maintenance and purchasing teams across the US, Canada, Mexico, and South America. Send the part number by WhatsApp or email and our team will confirm the belt or suggest an equivalent. For drives using multiple belts, replace them as a set to keep load sharing even.

Frequently asked questions
- How do I confirm the 5M 387 JB is the right belt for my drive?
- Check the marking on the back of the old belt. If it reads 5M 387 JB, it is the same belt. If the marking is unreadable, measure the belt length and compare it to 387 mm, and verify the pulley grooves match the 5M profile.
- What should I send to get a quote for this belt?
- Send the part number 5M 387 JB, the quantity you need, and a photo of the old belt or the drive nameplate if you have one. Our team will reply promptly with a quote or a question if anything needs to be clarified.
- Can I replace just one belt on a multi-belt drive?
- On drives that use more than one belt, it is best practice to replace all belts at the same time. Mixing a new belt with worn belts can cause uneven load sharing and shorter belt life.
