Customer Reviews (4.2 / 5 · 5 reviews)

Sebastian C. ★★★★★

Smooth as silk on my latest cabinet run—the 3/4-inch outer diameter tracked perfectly along the pattern bit's guide. Dead-on replacement that fit the 1/4-inch bore without any slop.

Sophia ★★★★★

Had to swap out the old bearing mid-project, and this one slid right onto the 1/4″ shank with zero play. The 3/4″ OD runs smooth and true through a full pass on oak, no heat or wobble.

David D. ★★★★☆

The 1/4-inch bore seated snugly on my bit shaft without any wobble, and the bearing spins smoothly even at full router speed. Only gripe is the lack of any lubrication info in the packaging, but it's been holding up fine so far.
