[quote user="Dominic"]do you happen to know which models had the air bearing?[/quote] I have seen 777, 1500, 5000, Z1, 8000 with air suspension but I think Micro did also some lighter tables with air. All those models (with exception of 8000 and Z1) ...

Yes, I had 4 Micros 5000 and one of them was almost glued platter. You need to flip it upside down and hit with a small hammer to knock to the TT’s back, in the bearing. It will eventually slide out. To service Micro Seiki 5000 is kind of tricky… I d...

Is there any way to choose the "right wife" only by video and photos whithout trying her? ;) You are well experienced Romy, which are the symptoms of the "wrong", wobbling or worn out bearing when we buy Micro Seiki RX or SX? Anyway I would like to g...

Hi Measet,The original platter for the RX-5000 was gun metal which I replaced with a platter with a similar platter to Wellington's weighing about 50 lbs. , the other table came from Japan with a original stainless platter made by Micro Seiki (rare)...

I just acquired a Micro RX-1500. Without the platter on, the bearing unit turns very slowly suggesting a highly viscous oil. The spindle turns freely, but the feel to my fingers is like turning a spoon in honey. It undoubtedly will turn much more...

I was offered to buy Micro seiki RX5000. The seller sent me a short video. If you see it carefully you will notice that the platter moving slightly up and down. Is that that normal or this could be sign that the bearing is not in good condition?

Hi Wellington and fellow Micro-Seiki fans,I will have to agree with your findings about the CU-180 as well. I have tried a stainless steel mat with similar results.I own two RX-5000's and cant't stress enough the rebuilding of the power supply with n...

Hi Measet,The oil I would use is Zoomspout, it works great. I have a platter with a similar profile that Wellington has, my second RX-5000 has a stainless platter made by Micro Seiki with the same dimensions as the original gun metal platter.Just fli...

Jam, when you first mentioned ZoomSpark perhaps your spellchecker was hyper-active and you meant Zoom Spout. I think it’s this product, right?http://www.highsidechem.com/zoom_spout.htmlOK, so that is ISO 32 (at the bottom of this page) paraffin oil, ...

While my background is in engineering, I am not a metallurgist either. But I do know that 316L is considered an non-magnetic material (see https://greenwoodmagnetics.com/resource/what-is-the-difference-between-304-and-316-stainless-steel/). But even ...

I have not opened my bearing yet to change the oil, following the philosophy of “if it ain’t broke, don’t fix it”. It’s a different situation here than a car’s oil. The seals prevent the oil from being exposed to oxygen, moisture and other contam...

Wellington,It is my understanding that lead was used because it'a anti an anti-seize properties. The bearing fit is very tight and I suppose this helped with the lubricants of the period and is not a problem with modern synthetics.The bearing does no...

Measet,Thank you very much for posting this extremely valuable information! It adds to the data base for the 5000. I will have to translate it to English using the Google translator. Now, if someone could locate and post the RY-5500 schematic, we’d a...
|

I have to agree with Wellington. To be fair we both use stainless steel platters (heavier than stock) and use CU-180 mats to damp the platter which ensures an almost dead platter, way better than any acrylic, hard rubber and felt mat I have tried. St...

[quote user="mem916"] Oh, by suspension, I meant the tuned spring suspension that the versa (and many other 'tables) use to isolate the plinth platter, and arm from vibrations coming up through the floor and the stand. I don't think of a platter bear...

George,
I do not think that the 3 motors example of Clearaudio is applicable. Theoretically it correct and a single motor driving a platter coastally minor-swing it on it’s bearing. In realty the things are more completed. With enough mass of platte...

[quote user="hagtech"] I'm not convinced a constant side load on bearing is good. It causes assymetrical wear. Just seems to me a center balanced bearing with no lateral loads would be better. Merely an intuitive hunch. [/quote]

OK, I understand now when you talk about suspension and will translate to "bearing". I don't know if it needs to be the turntable or the stand but something needs to be responsible for isolation. I have heard good things about the vibraplane and wo...

I usually do not do the Audiogon posting. There are too many idiots in there and they are under too much protection of the douchebags that run that site. Not to mention that I well remember WHY I was “banned” from Audiogon to begin with:

Hi Romy,
First I want to say thank you for your opinion.
I have read your post several times and I will read it again to understand fully what you mean with my 8000 next to me. You have given me things to think of such as 'dirt that cause the scra...

The RX5000 platter is ball bearing and I feel that in some
cases if a platter has a direct path to mechanical ground then it is slightly better
than suspended platters, would it be oil, magnetic, air or a penicillin sustention.
There are two aspec...

Hi Micro Seiki guys!
From a few months I have RX5000 and of course this is great TT and even more if the platter is damped and upgraded with a proper mat.
Now I have offer from a seller of SX8000I. First I...
