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.

直線軸承間隙選擇需要考慮以下幾因素：

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

直線軸承和軸套孔立室的間隙值的變化會影響密封性，安置后一樣通常會減少間隙值。

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.

直線軸承在運行過程中，由于冷卻軸和環境差別，導致溫度，值降落。

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

由于膨脹系數差別而增長，導致軸和外殼質料或減少間隙值。

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

直線軸承的固定：

Fixation of linear bearings:

固定YTP直線軸承的時候，做好清潔之后，應該對YTP直線軸承及關聯部件的尺寸和精加工情況做好檢查，保證這些方面都不存在不良問題，確保部件質量可靠，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直線軸承內部必須清洗干凈后涂抹潤滑脂。

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

直線軸承壓入支承座時，應采用專用安裝工具壓靠外圈端面，不允許直接敲打YTP直線軸承，以免變形。

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.

導軌軸裝入YTP直線軸承時，應對準輕輕插入。如歪斜地插入，會使滾珠脫落，保持架變形。

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.

直線軸承裝入支承座時，不允許轉動，強行使其轉動，會損壞YTP直線軸承。

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.

不允許用止頭螺釘直接緊定在YTP直線軸承外圈上，否則會發生變形。

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

封閉調整型和開放型的YTP直線軸承安裝要注意用螺釘壓緊調整間隙，注意不要使預壓過大。

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.
