Description
OPTIBELT PJ 864 belongs to poly-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 PJ 864 and any equivalents.
The Optibelt RB PJ 864 is a Poly-V (multi-rib) belt with a PJ profile and an 864 mm length. When you need to replace a worn serpentine belt, the marking on the back of the old belt is the fastest way to identify what you are running. Read it off and send it to us with your quantity.
Markings on a Poly-V belt typically carry the profile and the length, so a belt stamped PJ 864 tells you the profile is PJ and the length is 864 mm. Copy the marking exactly as it appears, including any prefix or catalog number printed alongside it, rather than measuring the old belt on the bench. A stretched or worn belt can measure differently from its original length, and the marking is the reference the drive was built around.
This belt is listed at a PJ profile and 864 mm length, and the same size is also listed under Gates PJ 864. If your old belt is too worn to read, send a photo of the back of the belt and the drive it runs on. We carry the Optibelt RB PJ 864 and can confirm the profile and length against what you send.
For a quote, message us on WhatsApp or by email with the part number, the marking from the old belt if you have it, and the quantity you need. If the marking is faded or the belt is gone, tell us the equipment and the pulley arrangement and we will help confirm the right belt or suggest an equivalent.

Frequently asked questions
- Where do I find the marking on the belt?
- It is printed on the back of the belt, the flat side that runs against the pulleys. Wipe off dust or belt dressing and read the profile and length, for example PJ 864.
- Can I just measure the old belt instead?
- You can, but a used belt may have stretched, so the measurement can differ from the original length. The marking on the back is the more reliable reference.
- What should I send with my quote request?
- Send the part number, the marking from the old belt, and the quantity. A photo of the belt and the drive helps us confirm the profile and length.
