The Gates 3M 300 JB is a Polyflex JB narrow V-belt with a 300 mm length. When you need to replace a belt on a compact drive, matching the existing belt is the surest way to keep the drive running as designed.
Start by reading the marking on the back of the belt you are removing. Confirm that it shows the same brand, series and part number: Gates, Polyflex JB, 3M 300 JB. The 300 mm length is the figure to verify, so compare it against the belt in hand before you order.
If the old belt is worn, frayed or has lost its marking, measure its length and check the drive for any other identification. Send the part number, the belt's length in mm and a photo of the marking to our team. We carry the Gates 3M 300 JB and can confirm it against your application.
Polyflex JB narrow V-belts are used where a compact, high-speed drive needs a slim profile. Because this belt is 300 mm long, it suits small equipment rather than large industrial drives. If you are replacing more than one belt on the same drive, order the full set so all belts wear evenly.

Frequently asked questions
- How do I confirm the Gates 3M 300 JB is the right replacement?
- Check the marking on the back of the belt you are replacing. It should read Gates, Polyflex JB and 3M 300 JB. If the marking is unreadable, measure the belt length and send us the details for confirmation.
- What information should I send for a quote?
- Send the part number 3M 300 JB, the belt length of 300 mm and the quantity you need. A photo of the old belt's marking helps us confirm the correct item.
- Can I replace just one belt on a multi-belt drive?
- It is best practice to replace all belts on the same drive at the same time. Mixed worn and new belts can cause uneven tension and premature failure.
