replacing bearings in old machines

[jack forsberg]

often we need to replace old bearings that are no longer made. so we go to the bearing house for new ones.

is that all there is to it?

Pretty much in my experience, just as you detail in your video. Nice video by the way.

It's been my experience that a bearing house will save you $$$$ over going through the OEM.
I know that when I was racing bicycles I was using a $200.00 + Campagnolo titanium and carbon fiber bottom bracket and blew a bearing in it. Campagnolo wanted $83.00 for one bearing and there were no spares available in the US. The local "Bearing Dude" matched it and gave me an equivalent SKF bearing for $18.00.

You can also get a better quality bearing at your local bearing supply house. Original bearings aren't the highest quality, which is why they have to be replaced.
Accurate Bearing is also a good source.

these bearings in this case are from Accurate and there garbage that's why i am replacing them. not much for NTN bearings myself. i can get this NTN bearing from my bearing shop in town for $8 and the SKF explorer C3 for $12. there not special bearings and are very common. these bearings were in the saw for 1 year and look at this rubber seal on this NTN is melted

We had a Grizzly vertical (metal working) mill were I used to work and the bearings went out on it.

When I talked to Grizzly customer service, he suggested buying someone else's bearings. At least he was honest.

I sure miss having a mill to play with, even one wiyh bad bearings.

In my experience, badly worn or damaged bearings often point to a bigger problem with the machine. When I see them I try to look for runout on a bent shaft, vibration from somewhere, etc. Weather it is just a worn bearing or a bigger problem, having a good bearing supply place and a competent machine shop nearby makes life so much easier.
