Here are two types of this deep groove bearing 6401. The one with suffix ZZ indicates that the roller bearing has two retaining rings that guide the outer ring, and its material usually is metal. 2RS means bearing rubber seal on both sides of the bearing (non-contact).
The basic dimensions of the two are the same. The noise of 2RS is small, but the accuracy is not too high, it can't reach P5 level. Its sealing effect is better than ZZ. You can choose according to different usage conditions.
