The Optibelt PJ 1123 RB is a Poly-V (multi-rib) belt in the PJ profile with a length of 1123 mm. Before a new belt goes on, the drive itself is worth a look, since worn sheaves and misalignment shorten the life of any belt. This page covers what to check and what to send when you request a quote.
Start with the sheaves. Run a straightedge or a light across the grooves to spot wear, and check the ribs for burrs, corrosion or packed debris. A groove that has worn wide lets the belt sit low and slip. Confirm the sheaves are clean, true and aligned to each other before the Optibelt PJ 1123 goes on.
Then check the rest of the drive: pulley runout, bearing play, and the tensioner or idler if the drive has one. Any of these can take out a new belt quickly. The same size is also listed under Gates PJ 1123, so if the belt you are replacing carries that marking, the size matches.
To request a quote, send the part number Optibelt PJ 1123, the profile PJ and the length 1123 mm, along with the quantity you need. If you are unsure of the number on the belt, send a photo of the back of the belt and the drive, and the team can help confirm the right belt or suggest an equivalent.
