嚴(yán)格的純潔度要求。鋼的純潔度是指鋼中所含非金屬夾雜物的多少，純潔度越高，鋼中的非金屬夾雜物越少。軸承鋼中的氧化物、硅酸鹽等有害夾雜物是導(dǎo)致軸承早期疲勞剝落、顯著降低軸承壽命的主要原因。特別是脆性夾雜物危害很大，由于在加工過程中容易從金屬基體上剝落下來，嚴(yán)重影響軸承零件精加工后的表面質(zhì)量。因此，為了提高軸承的使用壽命和可靠性，必須降低冷拔圓鋼中夾雜物的含量。表面缺點包括裂紋、夾渣、毛刺、結(jié)疤、氧化皮等，內(nèi)部缺點包括縮孔、氣泡、白點、嚴(yán)重的疏松和偏析等。這些缺點對于軸承的加工、軸承的性能和壽命有很大的影響，在軸承材料標(biāo)準(zhǔn)中明確規(guī)定不允許出現(xiàn)這些缺點。
