1″ 路達刀軸承 x 3/16″ID – Whiteside B29

I’ve been through a few bearings on my Whiteside bits, and this B29 runs noticeably smoother than the original ever did. The 1-inch OD is a perfect match for my pattern bits, and it spins freely right out of the package.

The 3/16-inch inner diameter fits my bit spindle exactly, no wobble or play when I spin it by hand. This replacement bearing runs smooth and quiet through a full afternoon of edge work, so I’m glad I grabbed a spare.

The 1-inch outer diameter seats perfectly in the bit’s bore, and the 3/16-inch ID slides onto the arbor without any wobble. I swapped it in for a worn one and the flush-trim cuts came out clean right away.
