高精度轴承和江苏NSK轴承通过精密加工，所有类型的滚动轴承都能满足高精度要求，但在高精度应用中，江苏NSK轴承是应用***广泛、精度高、刚度高的角接触球轴承。

High precision bearings and Jiangsu NSK bearings through precision machining, all types of rolling bearings can meet the high precision requirements, but in the high precision application, Jiangsu NSK bearing is the most widely used, high precision, high stiffness angular contact ball bearings.

美国轴承公司ESS要求金属切削机床主轴有两列和短圆柱滚子。轴承有很多，其次是圆锥滚子轴承。

The American bearing company ESS requires metal cutting machine tool spindle with two columns and short cylindrical rollers. There are many bearings, followed by tapered roller bearings.

目前，由于江苏NSK轴承加工技术的发展，江苏NSK轴承的实际误差大多低于标准值1/2，如机床NSK轴承的圆度。机床的LL为0.3米，用于NSK轴承的计算机为0.25米。

At present, due to the development of NSK bearing processing technology in Jiangsu, the actual error of Jiangsu bearing NSK is mostly lower than the standard value 1/2, such as the roundness of NSK bearing of machine tool. The LL of the machine tool is 0.3 meters, and the computer used for NSK bearing is 0.25 meters.

在一般情况下，用户选择前三种类型的NSK轴承的精密江苏轴承。即使在这三种类型中，也不是每一种规格都有***的生产。必须在江苏NSK轴承公司或生产厂的样品上找到，或者在江苏NSK轴承销售部门找到。

In general, the user selects the first three types of NSK bearings for precision Jiangsu bearings. Even in these three types, not every specification has precise production. It must be found on the sample of Jiangsu NSK bearing company or production plant, or found in Jiangsu NSK bearing sales department.

一般来说，P4级精密江苏NSK轴承更容易购买，而P2级精密江苏NSK轴承需要通过特殊订单获得。***次生产的精密产品应根据生产的新产品进行加工。

Generally speaking, the P4 grade precision Jiangsu NSK bearing is easier to purchase, while the P2 grade precision Jiangsu NSK bearing needs to be obtained through special orders. The precision products produced for the first time should be processed according to the new products produced.

获得高精度主轴轴承的方法可归纳如下。

The methods for obtaining high-precision spindle bearings can be summarized as follows.

（1）选择高精度江苏NSK轴承，并通过应用技术提高其精度。

(1) choose high-precision Jiangsu NSK bearing and improve its accuracy through application technology.

（2）应注意应用技术，如通过误差法提高安装精度，减少滚道变形和调整间隙，从而提高***精度和旋转精度。

(2) attention should be paid to application technology, such as improving installation accuracy by error method, reducing raceway deformation and adjusting clearance, thereby improving positioning accuracy and rotation accuracy.

（3）消除影响江苏NSK轴承精度损失的因素。

(3) eliminate the factors that affect the accuracy loss of NSK bearing in Jiangsu.

过度变形的***在于，如果轴被加载，过大的弯曲变形或扭转变形将影响轴类零件的正常工作。

The danger of excessive deformation is that if the shaft is loaded, excessive bending deformation or torsional deformation will affect the normal work of shaft parts.

例如，江苏NSK轴承中齿轮的弯曲变形将使齿轮啮合局部载荷，而由滚动轴承支撑的轴的弯曲变形将使轴承的内、外圈相互倾斜。当允许值超过允许值时，轴承的寿命将急剧下降。

For example, the bending deformation of the gear in the Jiangsu NSK bearing will make the gear meshing the local load, and the bending deformation of the shaft supported by the rolling bearing will make the inner and outer ring of the bearing incline to each other. When the allowable value exceeds the allowable value, the life of the bearing will drop sharply.
