Free Wheeling Bearings for Pulse Motors

Side by side comparison of the same bearings before and after the grease has been washed out and a thinner lubricant used.

If you aren't using Stainless Steel bearings make sure you add thinner lubricant before using them or they will rust very very quickly!!!

what I normally do is just soak the bearings in lighter fluid for about half an hour, and give them a shake occasionally... then rince them out with the nozzle of the lighter fluid can... there is a tiny gap on the guards so this is possible without having to remove the guards. But if you aren't using stainless steel bearings then make sure you get the new lubricant on there or they will rust pretty quick!

Can also clean the grease out and run them through with graphite powder. I have not found any wet lubes that can compare to it.

Completely agree! I have posted a response to your video.

My friend adapted a video head ( the spinng bit ) and that spins pretty good for his system.

Thanks Intro

The graphite may sound bad as you work it in and the bearing may seem a bit noisy after, but man does it go for a long ride. =] Be sure to blow out excess and you can clean with acetone after to eliminate any grease that shows up in the bearing after and it doesnt seem to get rid of the graphite.

Heating up the bearing helps to get the grease out.

Some bearings may need a couple workins . The 2 vids after that one show my 14:08 min rundown from 1200 rpm.

I've heard it helps to spray into them with WD-40.

Whoa! I want some! Time to write my letter to Santa ^_^

Yes, and smaller balls thus less surface area. The less surface area the better you are. Thus why tops spin so fast for so long. But I saw a video here on you tube of real ceramic bearings on a roller skate. It was spun up by hand and it ran for over a minute and a half before stopping..

@marthale7 Yeah...VCR bearings are great...

They are also stainless steel ;)

Been using a drop or two of transmission fluid for the lubricant with great results. Keep up the great work.

I paid about $50.00 for them but they are not the same quality as the excellent $150.00 bearings. I did not take them apart and look for grease. I had a cobbled together holder for them so was not a good test. So far VCR bearings have been the best I have encountered, I have gotten a true 18,000 RPM at 36V with them.
