The reasons to improve it....

Regarding the bearing materials, machining quality and design criteria, this bearing is built to be a nearly indestructable piece perfect for high utility studio and DJ applications.

This bearing provides lower opportunity for Brinnelling given the rubber damped vinyl sub plinth which communicates a lot more pounding than a suspended platter assembly. The SL1200/SL1210 was designed for easy and trouble free mobility which is perfect for a studio or DJ.

Replacement bearings are sold between 75-100 dollars and are available from Technics. They are very simple, very plain, and easy to replace.

Nothing I do in my trials could in any way impact the overall value of the table to its owner. The modified bearing could be tossed out and replaced with a factory bearing if the alpha user does not like the results.

If the modification is successful, I could easily machine plain steel, stainless steel or even a silicone nitride ball to the same geometry of a stock Technics bearing if the table is going to be used in high mobility applications.

I could even use graphite impregnated space age plastics as a thrust surface that would be superior to the stock Technics bearing.

If you want a sample of the thrust surface material I plan to evaluate, I am happy to provide one or several to you for your own testing. I will do so at my own expense. I have no agenda with this test. I am looking for ways to achieve quieter noise floors for my friends spinning an SL1200 turntable.

I have CDR test recordings of similarly improved bearings if you want to hear the results in your own system. My own turntable bearings show no sign of wear after more than a year of daily spinning and I am using a platter at least twice as heavy.
