Review on Shank Rabbet Router Bearings by FivePears by Kevin Hawkins

Firstly, I don't use these bearings in a milling machine environment. I would though if necessary. I use the whole set on the spindle with a couple of washers as shims to balance the mowing blades. I found two sets online but I needed a 7/8" bearing for the center hole of my JD blades. It was the same. I've seen videos on Youtube and they work perfectly. Couldn't believe the difference in my mowing experience after using them to balance my blades. Very inexpensive alternative to the $120-$180 supermagnetic version. Very satisfied.
