7/8″ 라우터 비트 베어링 x 내경 1/2″ – Whiteside B13

The 7/8-inch size tracks along my template cleanly, and the 1/2-inch ID seated snugly on the spiral bit without any wobble. I've put about three hours of trimming into oak plywood and it's still spinning true, so I'm grabbing a spare before I need one.

The 7/8" bearing slid onto my 1/2" shank flush trim bit without any wobble, and it tracked along the template edge perfectly for a clean cut. I've replaced bearings before and this one feels noticeably smoother during the spin-down.

I’ve been using this bearing on my spiral flush trim bit, and it runs smooth with no wobble. The 1/2-inch inner diameter fit perfectly on the shaft. Just wish the outer diameter was a touch larger for wider templates.
