DIN 5480 uses a side-fit system where the fit is determined by tooth thickness (shaft) and space width (hub). Hub Deviation Shaft Deviation Description Clearance (Slip) Easy assembly; "a" is loosest, "h" is line-on-line. Transition Tighter fit for precision alignment. Interference p, r, s, t Permanent or semi-permanent press-fits. 4. Verified Resource Documents
The DIN 5480 standard specifies the dimensions and tolerances for splines with a straight or involute tooth profile. The standard covers various types of splines, including: Component Type
The functional limit of the spline profile when considering manufacturing imperfections. This dictates whether the parts will slide together smoothly during assembly. Common Tolerance Classes
Always check the status of the standard. The current active version of the base standard is . However, this part was updated in 2025. DIN 5480-2 has a more recent edition: DIN 5480-2:2015-03 . A draft of DIN 5480-1:2025 was also issued. 38: The Number of Teeth (z)
DIN 5480 is a German standard that defines the dimensions and tolerances for splines, which are used to transmit rotational motion and torque between two shafts. In this write-up, we will provide an overview of the DIN 5480 spline dimensions and their significance in ensuring proper fit and function.
