8 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Involute splines have curved tooth profiles that provide better load distribution and self-centering, while straight-sided splines are simpler to manufacture but may have higher stress concentrations.
The spline design allows the mating component to slide along the shaft's length while maintaining rotational engagement, which is essential for adjusting steering linkage or absorbing suspension movements.
