90566481 supersedes older part numbers: 573119-02

DeWalt 90566481 — genuine DeWalt sealed ball bearing designed to restore smooth rotor rotation in angle grinders and sanding tools.

Precision dimensions: 7 mm inner diameter × 19 mm outer diameter × 6 mm width (607‑2RS style), rubber‑sealed both sides to keep grit and dust out and extend service life.

Commonly used in a range of DeWalt / Black & Decker grinders and sanders — example models that take this bearing include KA88 / G850GW / G750AK / KG100 and KA3000 (verify against your tool’s parts diagram for exact fit).

Sold individually to replace a worn or noisy bearing, this original DeWalt component drops into the factory location and brings quieter, smoother operation without replacing the entire gear assembly.

A compact, serviceable item that’s one of the common DeWalt spare parts kept for grinder repairs — ideal if you need reliable parts for power tools maintenance.
