I'm trying to locate a small bearing on a shaft for an instrument.


I initially thought of machining a couple of slots on the shaft and
using E clips or wire clips.


What about using a push on fastener like this:

Bearing: R4ZZ (5/8" x 1/4" x 5mm)
Shaft: 1/4" stainless steel
Load: normally zero end load, perhaps a kilo or three when handled.
Speed: Static to a few RPM



Thoughts on practicality?

Are there clips made for this purpose that have a small OD so as to not
exceed the inner race diameter?

Is there a standard name for these clips for bearing retaining
applications?


Cheers.



Here's a rough sketch of the arrangement:

Maybe the best idea is to try and source some of the push on retainers
and just try it. We've just done a batch that will last six months so
there is no time real urgency.

Rotor Clip TY-25 or TX-25. McMaster carries the the TX in stainless.

There are also retaining rings with an extra heavy cross section meant
to grip the shaft without a groove. I used to buy them form WM Berg.
