Description
GATES 3M 690 JB belongs to v-belt, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for 3M 690 JB and any equivalents.
This Gates Polyflex JB belt is a narrow V-belt with a 3M profile and a 690 mm length. Use the profile and length to confirm it matches the drive you are replacing.
The 3M profile identifies the belt's cross-section, while the 690 mm length gives you the outside circumference. Both values are marked on the belt and in the part number, so you can compare them directly with the belt you are removing. If the old belt is worn or the marking is unreadable, measure the length and note the profile before ordering.
Polyflex JB belts are used in compact, high-speed drives where a standard V-belt would be too large. This belt is suitable for maintenance and OEM replacement where the original specification calls for a 3M profile and 690 mm length. Check the pulley grooves for wear and alignment before installing a new belt.
To request a quote, send the part number 3M 690 JB, the profile, and the length. If you are unsure about the exact belt, our team can help confirm the right one or suggest an equivalent based on your drive details.

Frequently asked questions
- What does the 3M profile mean on this Gates Polyflex JB belt?

- How do I confirm the 690 mm length?
- Measure the outside circumference of your old belt, or read the length marking on its back. The 690 mm length in the part number should match that measurement.

- Yes. Send us the drive details, pulley dimensions, and any markings you have. We can help identify the correct belt or suggest an equivalent.
