Bearing for roll necks of rolling mills

Bearings used in roll necks must be capable of performing even in severe environments such as heavy load and high-speed rotation. JTEKT has adopted a newly developed hardened steel for bearings, thus drastically improving the rolling fatigue life, toughness and corrosion-resistance compared to conventional models. JTEKT also offers a premium model which has had fatigue life and corrosion-resistance enhanced even further through a special heat treatment process.
