Genuine Makita ball bearing 210054-1 — a sealed 6000LLU deep‑groove bearing (10 × 26 × 8 mm) — designed to support the rotor/shaft assemblies in Makita demolition hammers and rotary hammers; the LLU double‑lip rubber seals keep grease in and dust out for longer service life.
Common fitments include Makita HM1100C, HM1130, HM1140C and several HR2/HR28 rotary‑hammer models (for example HR2430 and HR2811F), so it’s the right replacement if those models show rough running or excessive play.
This original Makita bearing arrives pre‑lubricated and presses into the housing or onto the shaft during routine servicing — a compact, robust part that restores smooth rotation and reduces noise and wear.
If you need genuine Makita parts for a reliable repair, this 210054-1 bearing is a direct, metric‑sized swap that’s one of the standard power tool parts used in Makita hammers and hammer drills.
