128 Self Aligning Ball Bearing

This bearing is a 128 Self Aligning Ball Bearing. The outer ring has a spherical raceway and its center of curvature aligns with that of the bearing; therefore, the axis of the inner ring, balls and cage can move to some extent around the bearing center.  This type of ball bearing is recommended when the alignment of the shaft and housing is difficult and the shaft may flex. Dimensions of the bearing are 8mm x 24mm x 8mm. This bearing is made of Chrome Steel. you can buy it online at http://www.vxb.com/page/bearings/PROD/Kit7121
 

Help with bearing selection?

If you have the luxury to select what bearings to choose from, don't think of any bearings than the standard ones, the following ball bearing list will be your best selection in terms of price and availability, they are metric, so all dimensions are in millimeters, going metric is much more affordable, the following bearings are available in multiple designs.

Click on each of the links to find all the different design, let's take the first item as an example, 6000 ball bearing is just an open bearing that can be used inside any contained design like a housing that won't get any contamination, well that is not easy to find, that's why they invented the 6000-2RS & 6000ZZ, two closed designs, the first is usually marked 6000RS is a double rubber sealed closed bearing, the seal is installed in a pre-made outer ring groove, with grease already in there, nice, huh? as for the 6000ZZ, usually marked 6000Z, closed with metal shield with also grease inside.

Here is what the open Bearings look like, in our example it is the 6000 ball bearings

 The metal shielded 6000ZZ ball bearings, looks like this

And the rubber sealed 6000-2RS ball bearings looks like this

The 6000 bearings snap ring looks like this

Well, now is the time to select your ball bearings of the following list,

 Other designs like flanged and with a groove and a snap ring can help ease the assembly of your machine, but not as common as the ZZ & 2RS designs, so if I get to choose I would always go for 2RS design, well, as for electric motors, I suggest going for the ZZ design, they have lower friction factor because there is no contact between the shield and the inner ring, as for the rubber seal, installed in the outer ring and in contact with the inner ring.

The above list of ball bearings are from the 10mm bore to 50mm, again, you won't find more economical and efficient sizes, the most common material for the inner rings, outer rings and the balls are chrome steel, also knows as 52100, but can be available in stainless steel, ZrO2 ceramic, Si3N4 ceramic, SiC ceramic or even plastic.

Good luck and thanks for reading!
