深沟球轴承是滚动轴承中最为普遍的一种类型。基本型的深沟球轴承有一个外圈、一个内圈、一组钢球和一组保持架构成。深沟球轴承类型代号为6。 深沟球轴承主要用于承受纯径向载荷，也可同时承受径向载荷和轴向载荷。当其仅承受纯径向载荷时，接触角为零。当深沟球轴承具有较大的径向游隙时，即具有角接触轴承的性能，可承受较大的轴向载荷。深沟球轴承的摩擦系数很小，极限转速也很高，特别是在轴向载荷很大的高速运转工况下，深沟球轴承比推力球轴承更有优越性。 深沟球轴承结构简单，与别的类型相比易于达到较高的制造精度，所以便于成系列大批量生产，制造成本也较低，使用极为普遍。深沟球轴承除基本型外，还有各种变型结构，如：带防尘盖的深沟球轴承；带橡胶密封圈的深沟球轴承；有止动槽的深沟球轴承；有装球缺口的大载荷容量的深沟球轴承；双列深沟球轴承。 1、带防尘盖的深沟球轴承 标准的带防尘盖深沟球轴承Z型和2Z型两种，一面带防尘盖的是Z型，两面带防尘盖的是2Z型。 带防尘盖的轴承用在单独润滑较为困难、安置润滑油路和检查情况不方便的条件下，轴承在制造厂已填注了定量、定牌号的防锈、润滑两用锂基脂。每套轴承注入的脂量通常是轴承内有效空间的1/4～1/3，也可根据用户要求增减用脂量。注入的润滑脂通常能保证轴承在-40～+120℃的工况下运转。如果用户对轴承还有更高的要求，也可根据情况填注其他性能、牌号的润滑脂。带防尘盖的轴承经过注脂就可长期有效的工作，不需在使用期间再添加润滑脂。 带防尘盖轴承多用于中小型发电机、电动机的转子两端、汽车、拖拉机、空调器、风扇等处，以及对轴承的噪声振动有特别要求的场合。 2、带密封圈的深沟球轴承 标准型带密封圈的深沟球轴承有接触式密封轴承RS型（一面密封）、2RS型（两面密封）和非接触式密封轴承RZ型（一面密封）、2RZ型（两面密封）。 带密封圈的轴承的性能、添脂和用途与带防尘盖轴承基本相同。不同的是带防尘盖轴承的防尘盖与内圈之间有较大间隙，而非接触式密封圈轴承的密封唇与内圈之间间隙很小，接触式密封圈轴承的密封唇与内圈之间没有间隙，密封效果好，但摩擦有所增加。 有低噪声要求的场合，多用60和62系列的较小尺寸的深沟球轴承。不论开式轴承、带防尘盖型或带密封圈型的轴承，都可在订货时提出低噪声、低振动的要求。在我国JB（机械行业标准）中规定了V1、V2、V3各振动等级的低、中、高三个频带的振动允许值。在SKF公司还可提供超低噪声的轴承，这种轴承标有后置代号QE5。 3、有止动槽的和带止动环的深沟球轴承 标准型的有止动槽的深沟球轴承，后置代号为N，有止动槽并带止动环的轴承后置代号为NR，此外还有ZN，ZNR等结构变型。 有止动槽和带止动环的轴承除具备深沟球轴承可承受径向载荷的功能外，止动环可限制轴承轴向位移，简化轴承座的轴向结构和缩小轴向尺寸。 有止动槽和止动环的轴承多用于汽车、拖拉机等轴向载荷不大的工作部位。1，开式轴承是指不带任何密封盖的轴承。 2，同一个尺寸的轴承，客户可以选择不同的材料，等级。 3，以下尺寸为按国际标准的轴承的基本尺寸，如客户有不同的要求，我们可以定做。 4，相同的轴承有各种不同的代号和叫法，请确认自己需要的轴承的尺寸。
