Not its intended use but it works great as a mower blade balancer!

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. Theyre probably good enough, but this thing doesnt leave much room for error. Either it rotates left or right and needs more metal removed, or it doesnt rotate and its 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. Im sure you could fabricate some sort of magnet to keep the blade from falling off like the expensive ones, but Ive 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 doesnt move. The blade is never left there where it could be accidentally bumped off, I dont 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.

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 !

Great price on bearings for flush trim router bits

I actually am using this array of bearings as a mount for balancing mower blades. Works great in this application! Happy Dude right here!

Duraron menos que un merengue en la puerta de un colegio

Put the first bearing on a router bit, turned the router over and the seal fell out. Put on a 2nd bearing and this time the seal fell out after I turned the router on. Didnt even get to try them in action.

Used to make blade balancer

Purchased these to use as a balancing point for lawn mower blades. Seems to work fine so far.

What a waste of money. These WILL NOT fit a 1/4” shank bit. They are too small. You cannot make them fit. Not sure what they are supposed to be used for.
