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

滾珠絲杠螺母裝滾珠方法詳細步驟：

Detailed steps of ball screw nut mounting method:

1、把滾珠絲杠螺母和滾珠清潔干凈。

1. Clean the ball screw nut and ball.

2、把塑料擋珠器（滾珠反向器）放回到螺母內。安裝擋珠器時要注意擋珠器滾珠進出口與螺旋槽要平滑銜接。

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、在螺母內涂上油脂。

3. Grease the nut.

4、把滾珠放入螺旋槽內。注意，不是所有的螺旋槽都有填滿，是按照一個擋珠器是一個循環園的原則放滾珠，我看見你的螺母好像是4個擋珠器，那就是4個循環園。

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、把螺母擰入絲杠內（注意不要掉滾珠）。

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

6、旋轉螺母前進后退，檢查螺母運行是否順暢，如順暢這表示OK。

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

滾珠絲桿螺母裝滾珠其它方法

Other methods for installing ball screw nut

，不用戶自行拆卸和安裝螺母，特別是高導程滾珠絲杠。

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

在螺母意外脫落或你現在已經拆卸的情況下，請按照以下方法把螺母重新安裝上去：車制一個外徑略小于螺桿滾道底徑（小0.1mm左右）、內徑略大于螺桿端部外徑（大0.5~2mm）、長度長于螺母長度（長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).

將空心套的一端用泡沫包裝類軟物體堵住，穿入清洗干凈的無滾珠的螺母內，然后把清洗干凈的滾珠按每個循環溝槽一個一個裝入，裝滿一圈（空隙以0.5~1.5個滾珠直徑尺寸為宜）后輕輕轉動空心套，確認順暢后再推動空心套裝下一圈，直到全部裝滿為止。

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，將空心套連螺母一起套入螺桿軸端，一手頂住空心套，一手慢慢往螺桿上旋入螺母，直螺母順暢地全部旋入螺桿的有用螺紋溝槽部分。在螺母注油孔注入潤滑脂或潤滑油，旋轉螺母全行程移動2次以上，以確定運轉順暢，再注入一次潤滑油脂，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.
