Last attempt at plain bearing
Still wondering if I could run an 1 1/2" or 1 5/8" shaft in plain bearings at 2100 max.
Already convinced me to go with harder shaft, at least 4140 at 35C
planned on split bearing w/ shimmed cap & oil cups - this will be a mill spindle running mostly 200 - 800 rpm, but top speed is 2100.
Regular bearing bronze was mentioned, are there other/better bearing materials I could use?
I think flanged sleeve bearings would save space, take good radial load w/ closer support (no seals). Of course none of that matters if they sieze!
Gotta commit soon.
TIA for your help
