What may cause premature failure of ball screws or ball nuts?

In the working operation, the ball screw will always produce some friction. Under the appearance of these friction forces, the ball screw will wear to a certain extent. When the ball screw is used for a certain time, the ball screw will be damaged. This is the process of ball screw damage, but besides, there are other reasons that will cause ball screw damage, such as unreasonable use of staff. What are the reasons for ball screw damage?

1. The clearance of the ball screw guide rail is not appropriate.

When we install the ball screw, if the installation is not in place, the ball screw clearance may be too large. If this happens, when the ball screw is working, it will be easy to have a big impact. Under the influence of this situation, the wear speed of the ball screw will be greatly accelerated. If we want to solve this problem, we need to disassemble the ball screw and install it correctly.

2. Causes of lubrication

Before the ball screw is used, we need to lubricate it. At this time, some inexperienced novice employees may not be able to grasp the usage of lubricating oil. If the lubricating oil used by the novice ball screw is not enough, in this case, the ball screw will generate more friction when it is used, which will also have adverse effects on the ball screw. Therefore, at this time, the novice should add more lubricating oil to the ball screw for lubrication.

3.Excessive speed

Exceeding the ball nut critical speed can lead to pickup fingers breaking, which will allow to the ball bearings to come out of the nut. Exceeding the screw critical speed will cause the screw to whip or vibrate and cause misalignment. Shaft speeds resulting in screw surface speeds above 8,000 inches per minute will reduce rated life.
