Factor of Tooth Side Contact
The factor indicates the load is not spread evenly on all the spline teeth because of production and assembly inaccuracy. At a common and higher mounting accuracy, it is supposed that one half of teeth carry the load (K s = 0.5), for splining with higher production inaccuracy the load is only carried by one third of teeth (K s = 0.3).
