Well, this one was bugging me today, so I did some digging and the good Mr NTN came up with the info.
edit I guess it's friction/heat that's the issue?? OK angular contacts may not have the load capacity of rollers, but usually have lower coefficient of friction (1.2....2) than tapered rollers (1.7....2.5). I did see that there's been some recent advances in roller bearings pushed on by trying to get better efficiency in automotive, but they don't seem to be generally available at a nice priceLast edited by Voicecoil; 29-04-2020 at 08:50 AM.
