Metal Manufacturing

Withstanding the toughest of operating conditions in metal production.

ROLLING MILLS

NTN’s roll-neck bearings feature a four-row, taper setup that effectively supports both radial and axial loads. Most bearings are available with seals, and the bearing boxes can be designed in compact configurations since thrust bearings are eliminated.

NTN roll-neck bearings are also available with EA™ surface treatment and RustGuard™ corrosion preventative for especially harsh applications.

NTN's EA prefix designates the use of case-carburized bearing steel that has a special surface heat treatment modification. This combination gives the bearing significant protection against shock loading, as well as greatly extended fatigue life when operating in contaminated lubrication.

If corrosion is a concern, RustGuard™ is a manganese phosphate coating applied to bearing rings and rolling elements. This special coating extends bearing life by up to 100% and is especially effective for controlling downtime-induced rust. So, when your line is ready to start back up, you can be sure your bearings are too.

CONTINUOUS CASTING MACHINES

Continuous casting machines subject bearings to some of the most extreme conditions possible. Bearings face high temperatures, high loads, low speeds, and water splash. With dimensional stability up to 200° C, a high capacity for misalignment, and the highest load rating in the industry, NTN high-load capacity sphericals are an ideal solution to the unique demands of casters.

SAFS PILLOW BLOCKS

SAFS type pillow blocks are made of high-quality cast steel in a two-piece split design for ease of installation and inspection. The most modern machining equipment and exacting quality control assure maximum life and reliability. Triple-seal rotating rings eliminate debris ingress, and unique relubrication design channels apply lubricant directly through the housing to the center of the bearing, for immediate penetration to all working surfaces.
