Early SOTA vs New Something: Conundrum

Actually, a well designed bearing for the application with adequate lubrication will never wear out. Dirt, heat, overloading and neglect are the demise of any bearing. The trick is for the bearing to never have metal to metal contact. The lubrication is the sacrificial material.

Back in the 1980s I changed the oil in my wife’s 1983 Honda Accord every 3000 miles. When I took it in at 50,000 miles for the valve clearance adjustment the mechanic called me out and showed me my engine. It was clean inside and the machining marks were still visible on the cam lobes. He remarked that it was obvious I kept the engine well maintained.

Same thing with my Sota turntables over the years.  I remove the platter, clean and relube the bearing every few years.

Mijo, On 9-26, you wrote, "So don't DD motors, it just takes them longer. The thrust bearing gets noisy and wow and flutter specs also deteriorate."  To the casual reader this sentence implies that there is a special problem with the thrust bearing on a DD turntable that does not apply to a belt drive turntable. I subsequently lodged an objection.

On 9-30, in response to my complaint about the above statement, you wrote, "As for bearings, THEY ALL WEAR OUT except the air or magnetic ones."  I agree, except air and magnetic bearings can also wear out, albeit in different modes and after longer time intervals.  Case closed.

As to your fear of "large oscillating magnetic fields", I can only wonder whether you were frightened by a vacuum cleaner as a child, because you mention it so often.

Hey man, some vacuums are really loud and frightening.  And smelly.

I seriously enjoy the @lewm ​​​​@mijostyn sparring. 

It's not "sparring". 

Spar: To engage in argument, typically of a kind that is prolonged or repeated but not violent.
