| titleOfInvention | Rolling member for machine tool and rolling bearing for machine tool |
| abstract | A rolling member for a machine tool and a rolling bearing for a machine tool that has a long life even in a harsh environment while suppressing the content of alloy elements. SOLUTION: An outer ring 11, an inner ring 12 and a ball 13 of an angular ball bearing 1 for supporting a main shaft of a machine tool are 0.7 to 1.1% carbon, 0.3 to 0.7% silicon, and. 3-0.8% manganese, 0.5-1.2% nickel, 1.3-1.8% chromium, 0.1-0.7% molybdenum and 0.2-0.4% It is composed of steel with the balance of vanadium, balance iron and impurities, silicon + manganese 1.0% or less, nickel + chromium 2.3% or more, chromium + molybdenum + vanadium 3.0% or less , A high carbon content layer is formed, the hardness of the surface layer portion is 725 to 800 HV, the maximum particle size of the carbide of the surface layer portion is 10 μm or less, the area ratio is 7 to 20% or less, and the surface layer portion has 0 carbon content than the inside. .2 to 0.4% higher and the nitrogen content in the surface layer is 0.1 to 0.5% by mass.
