Continuous Casting

Segment Rolls

Top-End Performance
at the Top End

Bearings in continuous casting segments are exposed to unimaginably punishing stressors. Intense heat, massive loads, ultra-low speeds, water intrusion, scale, and mold powder contamination are constant challenges to operating life. Unplanned stoppage here is costly – in maintenance and replacement – and potentially impacts all downstream operations with lost production.

NSK segment bearing solutions have been purpose-engineered to withstand the environmental and mechanical forces prevalent in continuous casting applications. Advanced material and design technology is applied to effectively resist wear and support reliable roll operation.


Application-Optimized Solutions

With extreme durability and core toughness, NSK SWR™ Spherical Roller Bearings are engineered to deliver superior resistance to wear and the onset of progressive bearing damage in guide rolls of continuous casting machines.
