Hiwin rails / blocks

[JAZZCNC]

Thanks, here is a photo of mine. it really looks like to be Hiwin. The red protection is rubber. Is there a way to be sure that it's genuine or not?
If they are rejected, it means that they have a quality issue, is it right?

They look ok to me but difficult to tell without having in your hands. The copies tend not to have any Hi-win markings at all, they just look the same.
The etchings on the rails can sometimes be difficult to see and won't always be on short rails so check any longer rails you have.

Thanks everyone, I'll check again to see if I miss something. Next time I'll order with Fred.
I just noticed that the counterbore on the rails seems to be better on the Genuine (left) than mine.


And what do you think about the Chai Ballscrew RM... anyone has already tried them?

Hi BriceO,

Do you need a better closeup of the counter bore?

Thank you driftspin , it's clear that they are different now.

it's difficult to judge the quality of Chai's rails and ballscrews. I assume that it correspond to the price...
