6202 2Z - FAG Deep Groove Ball Bearing 15x35x11

Deep groove ball bearings are one of the most common style of ball bearings which support axial forces in both directions as well as radial forces. The bearing has a single row of balls retained in a cage. The 2Z (ZZ) suffix means the bearing has metal shields on both sides of the bearing which is designed to prevent dust/dirt from entering the bearing and to retain the lubricant/grease.
This style if very common for electric motors as opposed to the sealed 2RS style as their is less friction and they are designed for higher speeds.
