摘要:
A rolling device includes: an outer member; an inner member; and a plurality of rolling elements arranged between the outer and inner members, the outer member having a first contact surface which contacts the rolling elements, the inner member having a second contact surface which contacts the rolling elements, each of the rolling elements rolling against the first and second contact surfaces. At least one of the outer member, inner member, and rolling elements is formed of steel containing: C of less than 0.6 wt %; Cr of 10.0 wt % to 22.0 wt %; Mn of 0.1 wt % to 1.5 wt %; Si of 0.1 wt % to 2.0 wt %; N from 0.05 wt % to less than 0.2 wt %; Mo of 0 to 3.0 wt %, and V of 0 to 2.0 wt %; and the balance Fe and inevitable impurities, the steel satisfying C %+N %.gtoreq.0.45 wt % and containing retained austenite of .ltoreq.6 vol %. The rolling device has excellent characteristics in fatigue strength, wear resistance, corrosion resistance, and acoustic characteristic.
