The SAE-SMB axle housings have very high fatigue resistance and a long lifespan, particularly thanks to their spindles, which feature:
- An optimal profile at the connection zone with the rest of the axle housing, with no abrupt section changes
- Simultaneous machining on both sides, perfectly symmetrical
- Surface treatment through roller burnishing The hollow, compact, and large-diameter spindles also allow for a reduction in the length of the hub.
