Super Wear-Resistant (SWR) Spherical Roller Bearings

NSK SWR spherical roller bearings are engineered to deliver superior resistance to wear and the onset of progressive bearing damage in the guide rolls of continuous casting machines. As an effective countermeasure to heavy loads at ultra-low speeds, debris and water contamination and roll bending stress, SWR spherical roller bearings deliver longer operating life and mitigate unplanned maintenance downtime.

Operating Benefits

Superior wear resistance – 3 times that of conventional bearing steel
Improved flaking life property – 5 times that of conventional bearing steel
Higher toughness of material core (prevention of crack damage) – 5 times that of conventional bearing steel
Improved bearing durability extends segment roll operation, reducing maintenance costs and preventing unplanned downtime
