3/8インチルータービットベアリング x 内径1/8インチ – Whiteside B1

I was worried about finding the right replacement, but this bearing's 1/8-inch inner diameter seated perfectly on my bit’s shank, making the swap easy. The smooth rotation is noticeable, and it’s quieter than the old one was at the end of its life.

This bearing is a perfect fit for my 3/8-inch bits, and the 1/8-inch inner diameter was spot on. It runs smoothly and quietly, keeping my cuts accurate without any wobble.

Exactly what I needed to get my old router bit back in service. The 1/8-inch inner diameter fit perfectly and the bearing spins smoothly without any wobble. Saved me from having to buy a whole new bit.
