Ball Splines ISO 23848

Ball Splines ISO 23848

Ball Splines ISO 23848

(OP)
Has anyone done much ball spline calculations?  I am trying to determine load ratings.

Iso released a new ball spline document 11/15/09.  

ISO 23848-1: Machine tools -- Ball splines -- Part 1: General characteristics and requirements.

ISO 23848-2: Machine tools -- Ball splines -- Part 2: Dynamic and static load ratings and rating life.

Has anyone read these?  They seem so incomplete and flat out wrong I don't know how they can be published.  For instance, equations that only have units of mm or unitless and the result is supposed to be Newtons.

Does anyone have any suggestions on good resources for calculating ball spline load capacities?
