1-1/8″ ルータービット用ベアリング x 5/16″ID – Whiteside B25

The 5/16″ inner diameter seats perfectly on my shaft with zero wobble, and the 1-1/8″ outer size tracks along the template edge exactly as it should. I've put it through a few hours of solid routing and it spins smooth as silk, no heat buildup at all.

I was worried my old bearing was causing some wobble, but this replacement slid right on and the bit now runs perfectly smooth—exactly the 5/16 ID I needed.

Installed this bearing on a Whiteside bit that had a worn-out one, and the 5/16″ inner diameter fit perfectly. It runs smooth and true on the router table now, quiet as can be.
