Loading a Standard Ball Nut Video III
When Arbor WILL Slide Over the Machined Journal
Assembly a standard ball nut onto a machined ball screw must be done with care to insure proper loading of the ball nut. If not done properly, internal bearings can become misplace out of the bearing circuit which will reduce life and increase ware, and possible locking of the ball nut on the ball screw. In certain circumstances, the ball nut and ball screw can be permanently damaged.
Each ball nut comes with detailed instructions on how to properly load the ball nut on the ball screw.Figure 1
