Milwaukee 2780-20 (2) Ball Bearings Replacement

소개

Do you know what happens when your grinder overheats? If not, this is a quick guide on how to change the ball bearings. A ball bearing is a ring consisting of small solid metal balls between a wheel and a fixed axle, in which the rotating parts and stationary parts are separated to reduce friction. A damaged or worn ball bearing will reduce the performance of your grinder and ultimately destroy it completely.
