Router Bit Bearing Question

Can I use a hardware store bearing on a router bit or is there something special/unique about router bearings?

A bearing is a bearing. I've hear that there are only a few companies in the world that make them now. Same for TVs and major electronics. I've never seen any at the hardware store that small.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

Actually I was looking for a larger one.... 1 1/2" diameter.

Use a rub collar on the existing one. This is the general idea. I have a set of four that came from Woodstock or Woodriver or wood something I think. https://www.woodstockint.com/product...rs/rub-collars Some of the rabbeting sets I've seen use them for the larger sizes.

Normally router bits have some various sized holes that are not common to shaft bearings. I have noted too that different brands have different hole sizes for same profile bits. Most bit companies sell the bearings separate for their bits. it is the off shore bits that are a problem replacing bearings with the same size holes. Also have to contend with metric and imperial hole sizes.

Huh, now that's interesting. No use for one, but still interesting. I guess you guys run across stuff like this, that I've never even heard of, because of your routing needs. Me, I just use the same style bits, year after year, 1/4" shank, 1/2" bit, 1" bit length, bearing on top. I never look for anything else, so I don't find anything else. But, they do just what I want, so I'm content. But still like to see what some of you come up with, educational you might say.

Wow first time I will disagree with Stick! Brg is mot a brg. After 42 years in the power transmission bearing business I think anything that has speed or load needs precision. Chinese manuf. is the lowest grade right now but getting better. SKF, FAG, are from Europ. NTN, NSK are from Japan. Fafnir which are now Timken are USA. Most brgs are metric but inch diameter though less common are available. Suppliers such as AIT ( Applied Industrial Tecknologies), Kaman and Motion Industries are the big boys in the States and will be able to help you. Possibly even on line. There are some brgs with inch inside diameter and metric outside diameter and width. Make sure yo measure. Bearings are available with seals and shields amd are prelubed. Do. ot try to lubricate your self as the most common problem with brgs is over lub rearing to much heat. Sounds crazy but true.
Sorry for the long answer.
