NSK 7204CTYNSUP4轴承
机床用主轴轴承通常包括深沟球轴承、角接触球轴承、圆柱滚子轴承、双向推力角接触球轴承、圆锥滚子轴承和推力轴承等六种结构类型。
随着数控技术的快速发展，“复合、高速、智能、精密、环保”已成为当今机床工业技术发展的主要趋势。其中，高速加工可以有效地提高机床的加工效率、缩短工件的加工周期。这就要求机床主轴及其相关部件要适应高速加工的需求。目前，数控机床主轴轴承基本上限定在角接触球轴承、圆柱滚子轴承、双向推力角接触球轴承和圆锥滚子轴承等四种结构类型。
伴随着数控机床主轴向高速化发展，陶瓷材料（主要指si3n4工程陶瓷）因具有密度小、弹性模量高、热膨胀系数小、耐磨、耐高温、耐腐蚀等优良性能，从而成为制造高速精密轴承的理想材料。陶瓷轴承得到越来越广泛的应用，鉴于陶瓷材料的难加工性，精密陶瓷轴承多为滚动体是陶瓷、内外套圈仍由铬钢制造的混合陶瓷球轴承。
滚珠丝杠副作为精密、高效、灵敏的传动元件，除了应采用高精度的丝杠、螺母和滚珠外，还应注意选用轴向刚度高、摩擦力矩小、运转精度高的轴承。滚珠丝杠支承过去常用双向推力角接触球轴承、圆锥滚子轴承、滚针和推力滚子组合轴承、深沟球轴承和推力球轴承等。目前，滚珠丝杠支承采用最多的是60°接触角的单列推力角接触球轴承，而且，精度等级也是以p4及其以上级为主。
