The importance of these steel balls - the castor wheels of your robot and how they influence the movement of the robot. When you buy these steel balls they come brand new and they are very smooth. When you move with this there is almost no sound

While if you use an older one, it gets more rusty and if you move this ball, you hear a sound.

If this steel ball is very rusty, what happens is that it will have some influence of the movement of the robot. So, you should always check them and make sure that these are not very rusty.

Buy replacements to ensure the robot movements are least affected!
