Chrome-plated shafts, also referred to as ground shafts and induction shafts, are components that prepare a clean surface for bearings to operate, ensuring a longer lifespan for the bearings.
Induction shafts allow the surface shell to harden, minimizing the damage caused by balls while in motion. The absence of induction shafts leads to a faster degradation of the ball bearings on the shaft. Indeed, because they are hardened through heat treatment, they ensure a longer lifespan for the ball bearings.
