2206-2RS is a Precision ABEC1 Self Aligning Ball Bearing with both sides Rubber Sealed and is pre-lubricated with Grease allowing for use upon delivery. 2206-2RS has a straight bore for fitting on a conventional cylindrical shaft and a steel cage with evenly spaced balls for reduced friction, vibration, and noise. Our 2200 Series Self Aligning Ball Bearings have two rows of balls with a common, sphered raceway and permit angular misalignment of the shaft. This allows for applications subject to shaft deflections or misalignments between the shaft and housing.
