My friend, I don't get on and make rude comments. That is not the type of person I am. Please take this as educational not criticism. The process to install angular contact bearing is a precise, delicate process. You would never use power tools. The fit of the bearing is everything. The difference between .0002 of and inch is the difference in proper fit. The bearing housing or the bearing to the shaft needs to be press fit. If you press fit both the it will cause bridling. What it does is basically squeeze the bearing so the balls can no longer move as the should reducing the life of the bearing. Id suggest press fitting the bearing to the block, mostly because its easier. Also apply a light oil to the shaft and inside of the bearing so it slides smoothly onto the shaft. I noticed also that the shaft is beat to hell. Should have a very smooth finish. I can almost 100% say those bearing are trash now. It looks like the ball skew also need replaced or re machined. There is so much wrong here its hard to type all of it. Go the the manufacturer of the bearing and look up the process recommended for install and fallow it. EVERYTHING MUST NOT HAVE A SINGLE SCRATCH OR EVEN DUST ONE IT. Wear gloves and if there is even the smallest gouge or scratch stone with a very fine stone.
Thank you for taking all of this time writing such an exhaustive procedure! I will look into it. Research further. There is so much to know! I tried to get help from the bearing sales people with no luck. They told me they are preloaded and are simply installed face to face. That’s all I could get from them. Again, thank you for bringing this to my attention. - Blaise
@@BlaiseBarrette yes if your using a single row bearing then you need 2 bearing for 2 direction. Another option is 1 double row bearing. I think your on the right track with using 2 for higher load. I agree it is a lot. I dont know all of it either. You can message me and i can try and answer your question.
I did ask the salesperson if there was such a shim for the preload but they told me that these bearing are made to be used in face to face as such. Not the greatest buying experience I must admit!
@@BlaiseBarrette Hi. I would double check that info. If your bearings are the original part numbers used in fadals then they definitely need a shim between the faces. Where did you buy your bearings? If from a normal bearing place they wouldn't know about the shim but if from a fadal parts supplier they should have included a shim. From all the reading I have done the only true angular contact bearings you can use without a shim cost a fortune from SKF etc. You can get a Chinese set of true angular contacts which I know of a few guys have tried. But definitely check again otherwise you'll have to pull it all apart again as you will have slop in the screw. Did you find a shim between the bearings you pulled out? You may be able to reuse it. Cheers.
@@v2rsvr843 thanks for your insights! There was no shim when I first disassembled it. Do we know what is the thickness of that shim? I could make one from shim stock maybe?
@@BlaiseBarrette Hi. Not of thickness. But if you search the net I sure you can find it. Or maybe msg fadalcnc or similar they will tell you. Definitely check with your bearing part numbers too. Maybe you have true angular contact bearings. Hope this helps.

@@ryanturner9958 Thanks Ryan!
I believe you are missing the shimming between the bearings for the preload otherwise will be sloppy.

There was 0.01” of backlash so I’m thinking a shim of 0.011” or 0.012” should be about good! Worth a try!
Bravo lartiste you have french accent are you French?

You did it wrong. You are missing a piece between the bearings.
CLOWN SHOW!
