Genuine DeWalt part 153559-00 — a small circular felt washer used as a cushioning/sealing washer in DeWalt mitre and sliding compound saw assemblies.

This felt washer restores correct spacing, reduces metal‑on‑metal wear and helps limit dust ingress around moving trunnion/arbor components; it’s supplied as a single replacement washer.

Example DeWalt models that list this part include DHS780, DWS780 / DWS780B2, DW706, DW708, DW716, DW717 and DW718 — check your tool’s model plate or exploded parts view to confirm fit.

If you’re servicing a saw, this original DeWalt washer is a direct, purpose‑made swap that keeps DeWalt parts diagrams correct and helps the rest of the assembly sit and rotate as designed. This is a straightforward replacement when refurbishing worn power tool parts.
