This is a ball bearing for your power tools. Due to the heat and constant pressure on your bearings, over time they will begin to fail. Depending on your usage, bearings are a commonly replaced part. This is because ball bearings reduce friction between rotating parts. If they are visibly damaged, you should replace them right away to avoid damaging your power tool.
