We are now going to insert the LM8UU bearings in the 3x y_bearing_holders. When you place the bearings you need to ensure that the rows of ball bearings are at 45° as shown in the image.

Insert the LM8UU bearings in the each of the 3x y_bearing_holders. Each bearing should be centred in the bearing holder. There are ridges in the plastic part which will align with the grooves in the LM8UU bearing.

Confirm that each bearing is aligned vertically as shown in the first image. It is very important to have all x3 bearings correctly aligned!

Keep the 3x y_bearing_holders ready for use later in this chapter.
