Might these serve in a Commando?

Without looking at specific sizes, spherical roller bearings tend to have a lower speed rating than would be required for an engine application. Otherwise yes they would be good, very high load capacity and also the self alignment

Better quality steel. Does that mean they have stopped farming out production to China or India or Vietnam or where-ever ? Unlikely. Scrap purchases n' re-smeltering ending up as new lampshades or even bearings. I hope this is good news and wonder why it came to this. Complaints or even recalls ?

They would help as expected even though they would do exactly what you expect them too - take up the crank ends pivoting and tipping binding inside case races. What will nullify the above function is the crank bows like a jump rope so one can run into binding in rod journals and the things attached to end of crank like cam and oil pump getting snatched apart and alternator rotor abraiding and melting inside of stator. The stiffer superblends may help rpm some by resisting the crank flex in the middle - some what better than if end free to trace an squashed cone in air.

Spherical swivel bushing in my Pachymayer .45 acp allowed barrel freedom to gimble to cycle freely yet lock up solid no slack at slide slams home and big bang goes off. Very smooth no vibration action with blunted recoil that gave sense of it being the Commando of big bore pistolas.

Spherical roller shaped ? I was told the Superblends were special in that the rollers were slightly barrell shaped to allow for crankshaft "whip" at higher R.P.M. s.

All Roller bearings are all slightly barrel shaped so shaft can kind of bend a bit while still conforming to support by the rollers. A spherical race allows the rollers and shaft to gimble so roller support stays about the same on the shaft but changes in the race profit but not in the race case bores to take the loads not to gimble.
No one but Norton calls their rollers 'superblends' so just PR to cover their tails while upgrading to modern style rollers.

Whew ! No blow ups .
