Frequently Asked Questions
What are DIN 5480 and DIN 5482 standards?
DIN 5480 and DIN 5482 are German standards that specify dimensions and tolerances for involute splines, ensuring interchangeability between splined shafts and hubs.
What is the difference between a bore and a shaft spline?
A shaft has external teeth (external spline), while a bore has internal teeth (internal spline). They mate to transmit torque.
