Hi!
Let's say I have a ER20 collet with shank (shown in green). Let's say I put it into some housing (black) along with two tapered roller bearings (dark and light blue). The lower bearing rides on the shoulder of the shank.
Would it be plausible to machine a fine thread onto the shank and use some kind of nut (red) to hold the construction in place and also manage preload?
I've seen a design where there instead of a nut there is some element that is held in place with a set screw. I don't think that's a good way to regulare preload, but maybe there's some problem with machining the shank?
Thank you for your time!
