The shaft must have a smooth, burr-free lead-in chamfer to prevent damaging the delicate rubber lip during assembly. Housing Bore Requirements
Type B features a bare metallic outer diameter. It offers a tighter, more precise press-fit inside the housing bore. However, it requires closer tolerances and smoother finishes on the housing cylinder to prevent static leakage. Type BS (Form BS) din 3760 pdf
The hardness of the shaft is crucial, especially at higher speeds. The minimum hardness required is . However, as peripheral speed increases, the hardness must increase as well:

The shaft entry must be chamfered and polished to prevent the sealing lip from turning inside out or cutting during installation.
A DIN 3760 PDF is not just for purchasing; it is an installation manual. Adhering to the specified tolerances is critical for seal longevity.
