Recently I got introduced to some info about Chinese steel and how it's not very good. I'll have to do some checking to find that info again. But the end result was that Chinese steel just isn't that great at all. I want to say it's in their heat treating.
A supplier would be fine. But they're just suppliers. I'm hoping to find a manufacturer who makes quality, at a reasonable price. That way I can look for that brand in my normal places. Like Amazon.
Amazon sells what their sellers sell. Does Amazon actually sell anything?
From the top
1) Chinese steel mills make what they are asked to make
Good high quality steel is expensive to make so costs more money
US companies want CHEAP to maximumize their profits ( and that IS the problem ) so they buy products made from cheap steel
China makes steel to order , not for stock so the steel mills will make steel to any international standard
Having said that China does have their owns steel standards based on the Japanese JSI standards but with higher levels of Phosphorous & Sulphur ( then major impurities in steel ) and by doing this they simply buy iron ore from 5 different countries & mix the filthy ores with high quality ore from Aust so the output is the lowest grade of steel that is acceptable but is very very cheap and cheap is what the West wants because we are very greedy & selfish .
2) bearings are the most counterfitted product on the planet ( not Rolex watches ) and buying bearings from anonomous sources like Amazon is begging to be supplied with counterfit bearings which is why bearings must always be bought from a specialist retailer with a real shop that you can walk up to & throw a brick through the front window.
So use the retailer Star pointed you to and never ever get bearings off the www .
I tried some from various manufacturers in China and all of them will stamp what ever brand you ask for into the bearings is you buy them in big enough numbers and if bought in the thousands they will ever pack them in fake brand name boxes .
Which bearings there is cheap & there is good and those qualities are mutually exclusive
So Stars supplier sells quality brand name bearings (Koyo ) and budget house branded Chinese bearings for less critical applications, they are being honest about this and honest people are what we should be dealing with.
Then only time a quality bearing will be cheaper is when they are supplied in commercial tubes & not retail boxes and even then you are only looking at a 10% to 20% discount which is generated from bulk handling savings .
