At these prices there won't be any competition from Japan,USA or anywhere else.
Its too bad these guys are flooding the market with super cheap parts. Sure its great for hobbiest, but in less than 20 years, i bet ALL manufacturing will only done in China and the unemployment in the western world will be 30% . China has 1.3 billion people and they want what we have, and maybe its their time, who knows.

Next year that spindle will be about $100...maybe 3 for $100.

There hundred of chinnses spindle manufacture... quality is not all ways visual eg the rotor is the most import and hardest item to find a replacement if damaged...most cheep motors ie general use thinly coated insualting enmal wire coating on the rotor with time heat vibration dirt you will develop a short and prehaps melt thany internal plastic parts...

BTW, There is no wire in the rotor on an induction motor.

my mistake this a dc motor, thus its a stator. Same problem occurs.... regardless when motor heat up etc......

The sad part is when resellers dont even want you to know
what your getting but want maxuim $$$$$$$$$$ profit, then tell you there product the best but then dont want to inform you what brand / model your buying from just that it made in china?


Of those that have bought a spindle was there a owers manual that came with it, with info on the manufacture of the spindle ? contact info for service/ parts.

Sorry, but 99% sure these are rolled. I have some. They're nice, but not ground. Isn't it usually around C5 or C3 where you get into ground screws? Where as these are C7 (+/- 0.002" / ft).
