Linear bearings are a low-cost linear motion system used in conjunction with cylindrical shafts with infinite travel. Due to the point contact between the bearing ball and the shaft, the load is small. The steel ball rotates with minimal frictional resistance, allowing for high-precision smooth motion.

直线轴承间隙选择需要考虑以下几因素：

The selection of linear bearing clearance needs to consider the following factors:

直线轴承和轴套孔立室的间隙值的变化会影响密封性，安置后一样通常会减少间隙值。

The variation in the clearance value between the linear bearing and the vertical chamber of the shaft sleeve hole can affect the sealing performance, and the clearance value is usually reduced after installation.

直线轴承在运行过程中，由于冷却轴和环境差别，导致温度，值降落。

During the operation of linear bearings, the temperature and clearance values decrease due to differences in cooling shaft and environment.

由于膨胀系数差别而增长，导致轴和外壳质料或减少间隙值。

Due to the difference in expansion coefficient, the material of the shaft and shell may increase or decrease the clearance value.

直线轴承的固定：

Fixation of linear bearings:

固定YTP直线轴承的时候，做好清洁之后，应该对YTP直线轴承及关联部件的尺寸和精加工情况做好检查，保证这些方面都不存在不良问题，确保部件质量可靠，在尺寸及加工精度方面也都符合使用要求。

When fixing the YTP linear bearing, after cleaning, the size and precision machining of the YTP linear bearing and its related components should be checked to ensure that there are no adverse problems in these aspects, and to ensure that the quality of the components is reliable, and the size and machining accuracy also meet the requirements of use.

固定前，YTP直线轴承内部必须清洗干净后涂抹润滑脂。

Before fixing, the interior of the YTP linear bearing must be cleaned thoroughly before applying lubricating grease.

直线轴承压入支承座时，应采用专用安装工具压靠外圈端面，不允许直接敲打YTP直线轴承，以免变形。

When pressing the linear bearing into the support seat, special installation tools should be used to press against the outer ring end face. It is not allowed to directly hit the YTP linear bearing to avoid deformation.

导轨轴装入YTP直线轴承时，应对准轻轻插入。如歪斜地插入，会使滚珠脱落，保持架变形。

When installing the guide rail shaft into the YTP linear bearing, gently insert it into the center of alignment. If inserted obliquely, it will cause the ball to fall off and the cage to deform.

直线轴承装入支承座时，不允许转动，强行使其转动，会损坏YTP直线轴承。

When installing the linear bearing into the support seat, it is not allowed to rotate. Forcing it to rotate will damage the YTP linear bearing.

不允许用止头螺钉直接紧定在YTP直线轴承外圈上，否则会发生变形。

It is not allowed to directly fasten the outer ring of YTP linear bearing with a stop screw, otherwise deformation may occur.

封闭调整型和开放型的YTP直线轴承安装要注意用螺钉压紧调整间隙，注意不要使预压过大。

The installation of closed adjustment and open YTP linear bearings should pay attention to using screws to tighten and adjust the clearance, and be careful not to make the preload too large.
