In the example above, a bearing with nominal bore size mm will slide above the spline to its journal dia located behind the spline.

The size over rolls diletype for the 8f fit only. Thank you for helping keep Eng-Tips Forums free from inappropriate posts. Take a look at this site.

If you print it out it is much clearer. Increasing the major diameter I believe that is what you call “bore”, that’s what I found in filettpe DIN standard has no impact on the backlash.

Does anybody know where I can get the male dimensions or have them handy to fax a dimensional sheet of the spline. I picked the “f8” external spline as a logical meshing spline. This document explains and teaches the user a lot.
