Description
Overview:
The Makita 211279-0 Ball Bearing is a genuine replacement part designed to maintain smooth, reliable rotation in compatible Makita hammer drills. Built from durable, hardened steel with precision-ground races and balls, it reduces friction and supports radial loads at high speed, helping your tool run efficiently under heavy use.
