Roulement pour fraise à défoncer 1-1/4″ x 1/2″ID – Whiteside B16

I’ve used a few different replacement bearings, and this one fits tighter and spins smoother on my 1/2-inch arbor than the others I’ve tried. The 1/2-inch inner diameter sits flush without any wobble, which made all the difference for my trim router work.

The bearing seated perfectly on my shank with zero wobble, and the 1/2-inch inner diameter was exactly as specified. It spins smoothly even at higher router speeds, which was my main concern after the original one wore out. Saved me from buying a whole new bit, so I’m happy with the purchase.

I was worried about finding a drop-in replacement for a worn bearing on my favorite 1-1/4″ bit, but the 1/2-inch inner diameter seated perfectly on the shank with zero wobble. Spins smooth and quiet on the first test cut, exactly what I needed.
