Genuine Makita part 211031-6 — sealed deep-groove ball bearing (608LLB). Double rubber-sealed on both sides, nominal dimensions: 8 × 22 × 7 mm, engineered to support rotating shafts and reduce friction in gear/housing assemblies.
This single-piece bearing is the exact replacement used in several Makita tool parts models : for example, 9227C sander/polisher, the DA3010F drill, and the DS4011 drill — so it’s suitable when you need to restore smooth, quiet rotation in those housings.
Sold individually and ready to drop into the original bearing seat; fits the factory mounting/retainer arrangements shown in Makita parts diagrams.
