Description
Overview:
This Genuine Makita Ball Bearing (part no. 210054-1) is a precision steel bearing used to support rotating parts inside selected Makita power tools. It keeps shafts running true, reduces friction, and helps prevent heat and wear during heavy use. Fitted in the drive train, it restores smooth operation when an original bearing has become noisy or worn. Designed for Makita hammer drills, including the HM1100C and HM1130, it offers a direct, like-for-like replacement to maintain output and accuracy. Built from hardened steel with close tolerances, it withstands vibration and dust common on site and in workshops. Use it during routine servicing or repairs to keep tools performing reliably and to protect gears, armatures, and housings from unnecessary damage.
