深沟球轴承（GB/T 276-2003） 径向滚珠轴承的原始列表是应用最广泛的滚动轴承。它的特点是摩擦阻力小，速度快。可用于可同时承受径向载荷或径向和轴向联合载荷的机械零件。也可用于承受轴向载荷的机械零件，如小功率电机、汽车和拖拉机齿轮箱、机床齿轮箱、通用机器、工具等

基本参数

基本型深沟球轴承由外圈、内圈、一组钢球和一组固定架组成。深沟球轴承有两种类型：单列和双列。深沟球结构也分为密封和开放式两种。开式是指没有密封结构的轴承。密封的深沟球分为防尘封和防油封。防尘密封盖的材料由钢板冲压而成，仅用于防止灰尘进入轴承滚道。防油型为接触式油封，可有效防止轴承内润滑脂溢出。

轴承结构

深沟球轴承结构简单，比其他类型容易达到更高的制造精度，因此便于批量生产，制造成本也低，非常受欢迎。除基本型外，深沟球轴承还具有各种改性结构，如：带防尘罩的深沟球轴承、带橡胶密封件的深沟球轴承、带止动槽的深沟球轴承、滚珠缺口大负载能力的深沟球轴承、双列深沟球轴承等。 仪器仪表、电机、家用电器、内燃机、运输车辆、农业机械、工程机械、工程机械、旱冰鞋、溜溜球等

游隙：

轴承的径向游隙分为原载游隙、安装游隙和工作游隙。通常，轴承的原始径向游隙大于轴承运行时的游隙。间隙是轴承的重要技术参数，直接影响轴承的载荷分布、振动、噪声、摩擦、使用寿命和机械运动精度等技术性能。严格来说，轴承的额定动载荷随游隙大小而变化。产品目录中列出的额定载荷（C 和 C0）是工作游隙为零时的载荷值。如果间隙过大，轴承内部轴承面积会减小，滚动接触面上的应力会增加，轴承的运动精度会降低，振动和噪音会增加，轴承的使用寿命会缩短。它甚至会导致轴承在运行过程中“咬合”。因此，根据轴承类型和工况选择不同级别的轴承游隙非常重要。

Clearance:

The radial clearance of the bearing is divided into original clearance, installation clearance and working clearance. Generally, the original radial clearance of the bearing is larger than the clearance when the bearing is in operation. Clearance is an important technical parameter of bearings, which directly affects the technical performance of the bearings such as load distribution, vibration, noise, friction, service life and mechanical motion accuracy. Strictly speaking, the dynamic load rating of the bearing changes with the size of the clearance. The rated load (C and C0) listed in the product catalog is the load value when the working clearance is zero. If the clearance is too large, the bearing internal bearing area will be reduced, the stress on the rolling contact surface will be increased, the bearing's motion accuracy will be reduced, the vibration and noise will be increased, and the service life of the bearing will be shortened. It can even cause the bearing to "bite" during operation. Therefore, it is important to select different levels of bearing clearance according to the type of bearing and working conditions.
