The dummy shaft of the corresponding model shall be used for installation, and the steel balls of the corresponding model shall be provided. The imported ones shall be wear-resistant. For example, the dummy shaft of 16 shall be used for installation of 3.175 steel balls, and the dummy shaft of 32 shall be used for installation of 6.350 steel balls, etc

滚珠丝杠螺母装滚珠方法详细步骤：

Detailed steps of ball screw nut mounting method:

1、把滚珠丝杠螺母和滚珠清洁干净。

1. Clean the ball screw nut and ball.

2、把塑料挡珠器（滚珠反向器）放回到螺母内。安装挡珠器时要注意挡珠器滚珠进出口与螺旋槽要平滑衔接。

2. Put the plastic ball stopper (ball reverser) back into the nut. When installing the ball stopper, pay attention to the smooth connection between the ball inlet and outlet of the ball stopper and the spiral groove.

3、在螺母内涂上油脂。

3. Grease the nut.

4、把滚珠放入螺旋槽内。注意，不是所有的螺旋槽都有填满，是按照一个挡珠器是一个循环园的原则放滚珠，我看见你的螺母好像是4个挡珠器，那就是4个循环园。

4. Put the ball into the spiral groove. Note that not all spiral grooves are filled. The ball is placed according to the principle that a ball stopper is a circulation circle. I see that your nut seems to be four ball stoppers, that is, four circulation circles.

5、把螺母拧入丝杠内（注意不要掉滚珠）。

5. Screw the nut into the lead screw (be careful not to drop the ball).

6、旋转螺母前进后退，检查螺母运行是否顺畅，如顺畅这表示OK。

6. Rotate the nut forward and backward to check whether the nut runs smoothly. If it runs smoothly, it means OK.

滚珠丝杆螺母装滚珠其它方法

Other methods for installing ball screw nut

，不用户自行拆卸和安装螺母，特别是高导程滚珠丝杠。

First of all, it is not recommended that users disassemble and install nuts by themselves, especially high lead ball screws.

在螺母意外脱落或你现在已经拆卸的情况下，请按照以下方法把螺母重新安装上去：车制一个外径略小于螺杆滚道底径（小0.1mm左右）、内径略大于螺杆端部外径（大0.5~2mm）、长度长于螺母长度（长10~50mm）的空心套。

If the nut falls off accidentally or you have removed it now, please reinstall the nut according to the following methods: turn a hollow sleeve with an outer diameter slightly smaller than the bottom diameter of the screw raceway (about 0.1mm smaller), an inner diameter slightly larger than the outer diameter of the screw end (0.5 ~ 2mm larger) and a length longer than the length of the nut (10 ~ 50mm long).

将空心套的一端用泡沫包装类软物体堵住，穿入清洗干净的无滚珠的螺母内，然后把清洗干净的滚珠按每个循环沟槽一个一个装入，装满一圈（空隙以0.5~1.5个滚珠直径尺寸为宜）后轻轻转动空心套，确认顺畅后再推动空心套装下一圈，直到全部装满为止。

One end of the hollow sleeve is blocked by foam packing soft objects and penetrated into the cleaning nut without ball nuts. Then the cleaned ball is loaded into one circle of each circular groove, filled with a circle (the diameter of the ball is 0.5~1.5 ball diameter), then the air core sleeve is lightly turned. After confirming that it is smooth, the hollow sleeve is then pushed to the next circle until all the contents are filled.

再把堵口的填充物弄掉，将空心套连螺母一起套入螺杆轴端，一手顶住空心套，一手慢慢往螺杆上旋入螺母，直螺母顺畅地全部旋入螺杆的有用螺纹沟槽部分。在螺母注油孔注入润滑脂或润滑油，旋转螺母全行程移动2次以上，以确定运转顺畅，再注入一次润滑油脂，此完工。

Then remove the filler of the plug, put the hollow sleeve and nut into the shaft end of the screw rod, hold the hollow sleeve with one hand, and slowly screw the nut into the screw rod with the other hand until the nut is smoothly screwed into the useful thread groove of the screw rod. Inject lubricating grease or lubricating oil into the nut oil filling hole, rotate the nut and move it more than twice in the full stroke to ensure smooth operation, and then inject lubricating grease again to complete the work.
