The needle roller bearings spun smoothly as soon as I installed them, and the included M6 retaining ring held everything in place securely.

The needle roller bearings fit snugly and the M6 retaining ring locks everything in place without any wobble. Assembly was straightforward since the parts matched the drawing exactly. Saved me a good chunk of time compared to sourcing each piece separately.
