It is an authentic item sourced directly from original equipment manufacturer. It is generally used on Milwaukee angle grinders. This bearing helps to support armature and allows it to spin freely. Over time because of pressure and heat ball bearings will wear out and need to be replaced. Please note this sealed metal bearing is sold individually. Replacing this ball bearing is a relatively easy task. You would need a screwdriver, pliers and a rubber mallet to complete this repair. • Make sure the tool is unplugged. • Remove the side handle. • Remove the guard. • Remove the handle. • Separate the grinder. • Disengage the brushes. • Remove the fan. • Remove the gear case. • Remove the armature. • Remove the pinion gear. • Remove the front bearing. • Install the new bearing. • Reassemble and test the unit.
