The ball screw is under force. Ball screws are not allowed to withstand radial forces and should be fully considered in design. The force referred to here is the axial force, which is the "rated dynamic load" in the manufacturer's parameter sample.

滚珠丝杠的保护。常规产品不做特殊表面处理，不防水，不防锈，不防尘。如果在灰尘、铁屑等潮湿、不干净的地方使用，要注意防止异物落在螺杆上，尤其是螺母内侧。

Protection of ball screws. Conventional products do not undergo special surface treatment, are not waterproof, rust proof, or dustproof. If used in damp and unclean areas such as dust and iron filings, attention should be paid to preventing foreign objects from falling on the screw, especially on the inside of the nut.

滚珠丝杠的运行速度。合适的运行速度曲线可以提高丝杠的寿命。通常的设置是：匀加速---匀速---匀减速。并且速度是有限制的，这个值是动态的，可以参考DN值，一般情况是速度与长度成反比，与直径和精度成正比。

The running speed of the ball screw. A suitable operating speed curve can improve the lifespan of the lead screw. The usual settings are: uniform acceleration - uniform speed - uniform deceleration. And the maximum speed is limited, which is dynamic and can refer to the DN value. Generally, the speed is inversely proportional to the length and directly proportional to the diameter and accuracy.

滚珠丝杠的调整。本次调整主要针对螺母调整松紧度（预紧力），不建议用户自行调整螺母间隙。你可以试试垫圈式（两个螺母之间有环的那种）可以拆下来量一下环的厚度，然后做一个尺寸一样但比它厚一点的（取决于螺母的大小，厚度增幅不同，建议在0.05到0.15之间），安装试试看。

Adjustment of ball screw. This adjustment is mainly aimed at adjusting the tightness (pre tightening force) of the nut, and it is not recommended for users to adjust the nut clearance themselves. You can try the washer type (the type with a ring between two nuts). You can remove it and measure the thickness of the ring, and then make a size that is the same but slightly thicker than it (depending on the size of the nut, the thickness increase varies, it is recommended to be between 0.05 and 0.15). Try installing it.

滚珠丝杠的润滑。丝杠出厂时已润滑，短时间内无需添加润滑脂。一段时间后（视运行条件而定，约3～6个月），用户需要进行定期润滑。有脂润滑和油润滑两种。该润滑脂适用于中低速及常温场合。润滑脂可以是钙基或锂基的。润滑油适用于中高速、低温和高温场合，可根据工作温度和转速选择合适的粘度。

Lubrication of ball screw. The screw is lubricated when leaving the factory, and there is no need to add lubricating grease for a short period of time. After a period of time (depending on operating conditions, approximately 3-6 months), users need to undergo regular lubrication. There are two types of lubrication: grease lubrication and oil lubrication. This grease is suitable for medium to low speed and room temperature applications. Lubricating grease can be calcium or lithium based. Lubricating oil is suitable for medium to high speed, low temperature, and high temperature applications, and suitable viscosity can be selected based on working temperature and speed.

滚珠丝杠的清洁。长期使用后，螺母内部会残留金属粉尘和油脂的混合物，有条件的可以考虑清洗。

Cleaning of ball screw. After long-term use, a mixture of metal dust and grease will remain inside the nut. If conditions permit, cleaning can be considered.

滚珠丝杠的检查。丝杠长期使用后性能下降是不可避免的，但为了防止突然故障，可以多做检查。主要靠听和看。当你听到它时——有咔哒声吗？声音要么是珠子有问题，要么是循环器损坏。再看——观察丝杠滚道是否有划痕，特别是经常性划痕，三触——冰凉顺滑或暖暖滑是没有问题的。

Inspection of ball screw. It is inevitable that the performance of the lead screw will decrease after long-term use, but in order to prevent sudden malfunctions, more inspections can be conducted. Mainly relying on listening and watching. When you hear it - is there a clicking sound? The sound is either a problem with the beads or a damaged circulator. Looking again - observe if there are scratches on the screw raceway, especially frequent scratches. Three touch - cool and smooth or warm and smooth is no problem.
