Diagnosing A Ball Screw Problem

If your ball screw isn’t working the way it should, you may need to look into having repairs done. This type of screw usually serves a very important purpose. They’re frequently used in automobiles, and often have an impact on power steering. If you encounter an issue, you’re going to want to address it.


However, not everyone understands when a ball screw needs to be replaced. Here are a few signs of a problem with a ball screw:

screw1Do You Have Less Accuracy Than You Did Before?

If the device that uses the ball screw is less accurate than it was in the past, then the screw may be worn down, dirtied or damaged. A ball screw can be negatively impacted by dust and dirt. If there’s a lot of build up around the screw, you may not be able to steer with accuracy.

If you’ve noticed a drop in your accuracy, have a professional look at your ball screw. They can figure out whether the screw is the culprit, or whether you have another kind of problem.

Is There An Alignment Issue?

If it looks like something is wrong with your screw, there’s probably some issue afoot. Again, have someone come and look at your screw with a trained eye. They should be able to get to the bottom of this.

Is The Nut Accessible?

If you have access to the nut, try unbolting it and rotating it. If it feels rough to you, then it has probably been worn down. Remove the unit before it becomes even more damaged.

When you’re looking at the nut, you should also make sure that it’s properly aligned. Sometimes, a minor alignment issue can seem like a big problem. If you notice an issue that you can take care of on your own, you should do that. You might be able to resolve this problem completely.

Check For Steel Balls

If there are steel balls on the floor, then there’s a serious problem. Shut off the machine immediately, and leave it off until someone can fix it. If you leave an issue like this unaddressed, you might wind up seriously damaging the machine. A problem like this could also cause an injury.

If a ball screw has failed, you’ll need to figure out why. Sometimes, the issue is minor. If there’s an alignment issue or a build-up of dust, you can take care of that on your own. In other cases, you may need to enlist the help of a professional repair team.

They can fix your old ball screw, or can manufacture a new screw for the device. They won’t just be able to resolve the current problem; they can take steps to enhance the performance of the device. Working with a professional could pay off.
