I have a question about bearing fit up. I am building something that has a driven shaft with two bearings. I made the bearings to be a press fit on the shaft and left a .001" slip fit on the outer clearance, as I that was the recommendation by the bearing companies. My question is on retaining these bearings. The shaft will be driven by a gear system with a decent amount of backlash, so I am not sure if I will get any axial load. As I spin the shaft by hand, the bearings spin in housing and if I apply some axial load while spinning, the bearings with spin properly.
I set up the bearing retainer to have .001" clearance as well, but now wondering if I should tighten this up to hold the bearing's outer race captive. The housing is aluminum, so I am afraid of the bearing spinning in the housing and fretting/wearing.
I suppose the fulcrum of gear teeth will apply some axial force and this may be enough. Also, the bearing is brand new and therefore a bit tight.
This is my first work with bearings and would appreciate some guidance.
Thanks for your assistance.
