Retrofitting a 1986 Maho MH400E

Lol

The only source i have found for ball bearing grade balls sells 1000 balls minimum, and if the balls are not standard (oversized), then 15000 is the minimum order. Any help appreciated here.

www.precisionballs.com/catalog/index.php

is one US source

Thank you
John

Thank you for that, the size is 3,5 mm. like those

More than that I think its suggested that the balls be in alternate sizes (spacer balls and load bearing balls)

The micrometer reeds 3,499. The only solution is to send samples to the supplier and he will responsible to proper measure the balls with the his advanced measurement tools, and then send me the proper sized replacements. Or even better solution is to find some company on Europe to send the whole ballscrew, to replace all the balls and seals. The only one that I have found has never answer back.
