Wolfride Rabbet Router Bit Bearings Replacement Bearings for Router Bits | Inner Dia. 3/16” & Outer Dia. 3/8", 1/2", 5/8", 3/4", 7/8", 1", 1-1/8"

Saw this on a You Tube Vid being used as a mower blade balancer and glad I did. I mounted it on a 2x4 at one end of the shelving in my basement. Drilled a level 1/4" hole a little over an inch deep and pushed the shank in the hole. Tried it out today and it worked great !

Works well

I mounted this horizontally on some shelving next to my bench grinder. I just drilled a hole slightly smaller than the shaft and then hammered it in. I use it to balance lawn mower blades while sharpening them. It just happens to have a bearing that fits the center hole on my Craftsman lawnmower perfectly. I trust this way more than those cheap balancers that have the blade rest flat on top of it. Those you have to eye ball level. They're probably good enough, but this thing doesn't leave much room for error. Either it rotates left or right and needs more metal removed, or it doesn't rotate and it's balanced. I got the idea from seeing those ridiculously expensive wall mounted balancers and then going on youtube to see if there was a DIY version. Sure enough, some guy had a video using this item. I'm sure you could fabricate some sort of magnet to keep the blade from falling off like the expensive ones, but I've never had my blade fall off. The bearings are wide enough that the entire width of the blade is in contact with it. I only put it up there for a couple seconds, take it off and grind and then re-check until it doesn't move. The blade is never left there where it could be accidentally bumped off, I don't have anything I care about under it and I keep my hands close so i can grab it in the center, if for some reason it did pop off. Those magnets are pretty cool though. ;) Hope that helps you.

These perform well enough for me. I use them for routing binding channel for guitars where even little mistakes are not acceptable. They work in that situation just fine.

This router bearing set seems to be very good quality. The individual bearings spin easily and smoothly. There are also several extra retainer screws included. An added positive is that all of this router bearing set fits together on one spindle, promoting loss of individual bearings. My recommendation is a positive yes, I approve of this set.

Great price worked just fine.

One of the bearings came apart on the first use. I haven’t used any of them since.

I paired these bearings with a set of flush trim bits so that I could route smaller and larger patterns when using a template. This worked very well, and the bearings will provide a smooth cut along the template or edge of materials. The set also comes with four replacement allen screws just in case you drop one and can't find it.
