When you need to replace a Gates Polyflex JB belt, the marking on the old belt is your best starting point. This page covers the 5M 900 JB, a Polyflex narrow V-belt with a 900 mm length. Use the steps below to confirm it matches your drive before you request a quote.

Look for the code on the back of the belt. It should read 5M 900 JB, along with the Gates brand and Polyflex JB series. If the belt is worn or dirty, clean the area gently and check under good light. The 5M profile indicates a narrow V-belt construction, and the 900 mm length is the datum you need to match. Send that full code when you request a quote.

If the marking is unreadable, measure the old belt and note the cross-section. A narrow V-belt like this one is often used where space is tight and speeds are higher. Check the pulleys for wear, alignment, and any debris that could damage a new belt. Replacing belts in sets on multi-belt drives helps keep load sharing even. If you are unsure, our team can help confirm the right belt or suggest an equivalent based on your measurements and photos.
