Question:
A ball screw in one of my machines locked up and on inspection some of the balls have split in two pieces. Why did this happen?

Answer:
When balls are split in two pieces like peas it is invariably caused by extreme pressure. Usually this pressure is the result of a mis-aligned ball nut. It is important when installing a precision ball screw to ensure that the ball nut flange face mates perfectly with the contact face of the nut housing or a lateral twisting can occur causing extreme pressure inside the ball nut. It is possible, especially on nut housings that are bolted and pinned in position, that alignment of the flange contact face was changed because of a collision.
