滚珠丝杠是只承受轴向负载的部件，如果使其承受径向负载或力矩负载，可能导致滑动不良及产生振动、异常声响、从而缩短使用寿命。

Ball screw is a component that only bears axial loads. If it is subjected to radial or torque loads, it may cause poor sliding, vibration, abnormal noise, and shorten its service life.

导轨丝杠厂家提醒，引起滚珠丝杠承受径向负载、力矩负载的原因是周围零部件的轴心偏差和平行度误差，因此为了防止产生误差，必须正确地设计和组装滚珠丝杠的外围零件。

The guide screw manufacturer reminds that the reason for the ball screw to bear radial load and torque load is the axis deviation and parallelism error of surrounding components. Therefore, in order to prevent errors, it is necessary to correctly design and assemble the peripheral parts of the ball screw.

滚珠丝杠与支座组件的轴心偏差

Axis deviation between ball screw and support component

所谓轴心偏差是指，由固定侧支座组件所固定的滚珠丝杠的轴心与支持侧支座组件轴承的轴心偏差。

The so-called axis deviation refers to the deviation between the axis of the ball screw fixed by the fixed side support component and the axis of the support side support component bearing.

轴心偏差的容许值20μ以下（参考值）

Allowable value of axis deviation 20 μ Below (reference value)

滚珠丝杠与直线导轨的平行度

Parallelism between ball screw and linear guide rail

平行度误差是指，滚珠丝杠相对于直线导轨等的基准产生上下或左右方向的倾斜。

Parallelism error refers to the inclination of the ball screw relative to the benchmark of a linear guide rail in the up, down, or left and right directions.

倾斜的容许值1/2000以下

Allowable value of inclination below 1/2000

组装时的注意事项

Precautions during assembly

组装后如果发觉滚珠丝杠运行时有异常声响、移动时有被卡的现象，请旋松各零部件的联结后进行调整，待移动顺畅后重新组装。

If you find any abnormal noise or jamming during the operation of the ball screw after assembly, please loosen the connection of each component and adjust it. After the movement is smooth, reassemble it.
