1/2インチ ルータービット用ベアリング × 内径3/16インチ – Whiteside B3

Bearing runs smooth as butter on my dovetail jig, no wobble at all. The 3/16-inch inner diameter was an exact match for my bit, so it pressed right on without any fuss.

Used this to replace a bearing on a worn-out bit I've had for years, and the 1/2-inch outer diameter matched up exactly without any play. Spins smooth and quiet on a test pass through some cherry. Glad I could get a precise replacement instead of tossing the whole bit.

The inner diameter fit perfectly on my bit shaft without any wobble. Saves me from having to buy a whole new router bit set.
