Solving Friction Spikes in RA Cross Roller Bearing Joints

The RA cross roller bearing is a high-precision component where the rollers are oriented perpendicularly to each other. This allows a single-row bearing to carry radial, axial, and moment loads. While this is efficient, the rings of an RA series bearing are thin. This means the bearing lacks the structural mass to "self-correct" for imperfect housings. If your rotational system feels "notchy"...
