The Optibelt PJ 813 RB is a Poly-V (multi-rib) belt with a PJ profile and a length of 813 mm. The profile and length are the two numbers that matter when you are matching a belt to a drive, so order by those and by the part number.
The PJ profile identifies the rib pitch and cross-section family, and 813 mm is the datum length for this belt. Together they define what will seat correctly in the pulley grooves and run at the right center distance. If the marking on the old belt reads PJ 813, this is the direct match.
The same size is also listed under Gates PJ 813, which is useful when a machine carries a different brand name than the one you normally buy. Check the profile letters and the length in millimeters on the back of the belt before you order, and send that marking if you want it confirmed.
For a quote, send the part number Optibelt PJ 813 RB, or the profile and length if the number has worn off. If you are replacing a belt on a multi-rib drive, note how many ribs the pulley takes so the replacement matches the original setup.
