This product fit perfectly in the John Deere 318 mower deck.

Fit great in my mower deck. Quieted down my deck significantly.

Bearings appear to fit, but are unmarked. I will have a better idea on how satisfied I am when I see how many years they operate.

Specifications were as noted. Installed and fit perfectly.
