Methods of Antirotating a Miniature Ball Bearing?
Methods of Antirotating a Miniature Ball Bearing?
(OP)
I am designing a high speed (20,000 rpm) machine with 1/2" bore grease packed ball bearings. The bearings are installed with an interference fit onto the shaft. I am looking for a clever way to anti-rotate the outer bearing race and still provide axial motion relative to the stationary housing. The appoach must be low cost and very simple to assemble. We have experimented with using orings - we've had limited success. We have tried notching the bearing and using a key - but this makes assembly a bear. Is there any other common way that this is handle for small bearing like this? Thanks.

If the load varies in direction there will be creeping, even with a good fit. Some claim a wavt preload washer can help, but I think the rotating load direction will still try hard to drive the ring around, just like a 1000-1 ratio friction drive.

The bad news is they only have one left in stock at Amazon.
