Most gears in the metallurgical industry run with quenched and tempered output gears. However, gears made from this type of steel come with a significantly lower wear resistance than the much harder case-hardened variety. This is where SMS group's fatigue-resistant output gears make all the difference. Why? Because they are the most reliable solution for high-performance work roll drives.
What's so special about the SMS group case-hardening process for large gear wheels is that it boosts the torque capacity of new as well as existing gearboxes
