滚动轴承的材料
制造轴承部件所用的材料，对滚动轴承的性能和可靠性有很大的影响。一般对轴承套圈和滚动体的考虑因素包括：与承载能力有关的硬度、在滚动接触和不同清洁度下的润滑条件的耐疲劳性、以及尺寸的稳定性。对于保持器，要考虑的是摩擦、应变和惯性力，而在某些情况下还要考虑与某些润滑剂、溶剂、冷却剂和制冷剂等的化学作用。这些考虑因素相对的重要性亦受到其它工作参数的影响，如腐蚀、高温、冲击负荷或这些因素的综合影响。我们所用的材料为高碳铬滚动轴承钢，含有约1%的碳和1.5%的铬。这种滚动轴承钢的成份在制造和应用方面都达到了最佳的平衡。用于制造滚动轴承的碳铬钢通常是经过马氏体或贝氏体的热处理，硬度范围在58至65HRC之间。
