Got onto machtool. He is too busy to look at it.
Still trying to weigh up doing it myself
About $800aud for the bearings they are a common spindle set here In Aus so no lead time for parts.
I also changed out the y axis 7304 thrust bearings with proper 61deg contact angle preloaded ball screw support bearings.
Previous i was chasing 0.01mm in the bearings and they were new. Swapped them out, no shims needed as they have 350kg or so preload on them once assembled. Now have zero backlash on that axis from the bearings and probably last a heap longer as they are a higher capacity bearing for ball screws.
Not a kit just worked it out myself.
22 years in the bearing game helped as suppliers of this bearing set a pretty hard to find.
If it was 25mm inside dia I would have many manufactures to choose from.
Yep, I have (Had) water cooled ball screws, so there is an IN and an OUT port in the screw, which means 3 seals for the cooling, and 1 dust seal for the bearing.
Bit of an update.
I replaced x and y ball screws seals and thrust bearings. All were changed over to proper ball screw support bearings.
1 reballed the z axis.
