محمل لقمة الراوتر 7/8 بوصة × قطر داخلي 1/4 بوصة – Whiteside B21

I've been through a few cheap bearings that squeaked after a few cuts, but this one spins smoothly and feels much more durable. The 1/4-inch inner diameter fit my router bit perfectly without any wobble.

I opened the package and immediately noticed how smoothly this bearing spins compared to the old one it's replacing. Installed it on my flush trim bit in under a minute and ran a test cut with zero wobble.

This bearing fit my Whiteside flush trim bit perfectly, the 7/8-inch size was exactly what I needed. It spins smoothly with no wobble, feels like a quality piece for router use.
