6205 2ZNR Shielded SKF Ball Bearing with Snap Ring Groove
The metal shields on the ball bearing protect against the entry of dirt and so on. Shielded bearings also help to contain the lubricant.
A snap ring groove can simplify arrangement design as the bearings can be axially located in the housing by a snap (or retaining) ring, saving space.
SKF is the largest bearing manufacturer in the world and are known for high quality standards, which makes SKF ball bearings very popular.
