Accurate Strong Gantry

[Boyan Silyavski]

Some technical info and bearing sizes and data . There are some force calculators there and so on. May be you know them already but let be here on one place.


Here is the 3kw/3.2-4kw i believe also/ spindle with all sizes if you dont have it at hand. I took them personally :-) .This is the original Guanzhou spindle with the 4 bearings and the black rings. Maybe enough place that the attachment could be clamped directly at the spindle there.

Hope that helps. When i have time will sit also and see if i have some ideas.








These are the bearings and dimensions of the BT35 spindles for reference:








Here is some belt info. If i read it correctly best would be HTD3- HTD5 belt or GT belt even better . Dont be put off by the lower life the figures show. After all one belt is 1-4 euro only. One thing to note is that wider than necessary is not a good idea.
