This Milwaukee ball bearing is an OEM replacement part. It fits in assorted handheld power tools including various saws, routers, hammers, and shears. Bearings are used to hold moving parts while they rotate/spin. This lowers friction while stabilizing movement direction and angle. Ball bearings are a commonly replaced item because of their high wear role. Sold individually.
