Hi guys
Hope to hear from a bearing expert.
I have some 12" ballscrews,20mm dia 5mmlead with the proper bearings which appear to be NOOK.The ballnut is the only marked item.THK KX20797.Anyone know what the numbers mean?
I need a longer screw.What would be the max length recommended for 20mm.
Is it possible to buy longer screws with machined ends?
Also have 16mmdia 5mm lead with thk bk12& bf12 the ballnut is marked KX70322.
Same questions.
BTW from researching prices ballscrew or Acme are near in price if you use the proper angular bearings.
Larry
