Bosch 2604736010 — genuine Bosch toothed drive belt designed for Bosch belt / drum sanders. This is a timing-style (toothed) drive belt intended to transfer motor torque to the sanding platen/drum; dimensions for this part are about 225 × 17 mm with 75 teeth (Z=75), so it replaces the factory belt on older Bosch belt-sander models.

Fits example models such as Bosch 1274DVS, GBS75AE / GBS75A and PBS‑75‑A / PBS‑75‑AE belt sanders — check your 10 digit version number from the side of the machine to confirm fit.

Simple to install: remove the sander’s belt cover, swap the worn belt for the Bosch 2604736010 and re-tension per the tool’s service instructions. It’s the original Bosch replacement item-numbered for these sanders, made to match the factory tooth profile and width so the belt runs true and keeps sanding performance consistent.
