Handling Extreme Loads
Safely and Reliably

From the outset of the metal-making process, sequencing, timing and reliable motion are critical. In furnaces and converters, at temperatures exceeding 2,500ºF, thousands of tons of molten steel moving slowly and precisely in stages of limited rotation impose severe mechanical forces on supporting bearings. Any performance issues here could potentially shut down the entire mill.

NSK bearing solutions for furnaces and converters are application-optimized, engineered to operate with stability at high temperatures, accommodating heavy loads, low speeds and oscillating motion with predictably reliable efficiency.

Application-Optimized Solutions

Eliminate removing bull gears and dismantling drives and surrounding equipment. With NSK Ultra-large Split Roller Bearings, replacement time, maintenance costs and
production loss is reduced – considerably.
