How does the anti-backlash nut eliminate the clearance?

The anti-backlash nut lead screw is designed to eliminate the clearance between the screw and nut by incorporating a mechanism that reduces or completely eliminates the backlash or play between them.
One common type of anti-backlash nut uses a split nut design. It consists of two separate halves that are preloaded against each other. When the screw rotates, one half of the nut moves in one direction while the other half moves in the opposite direction. This action effectively eliminates the clearance between the screw and nut.
Another type of anti-backlash nut uses a spring-loaded mechanism. It includes a spring that applies constant pressure on the nut to keep it in contact with the screw. This constant contact ensures that there is no clearance or backlash between the screw and nut.
Both of these designs prevent any free movement or play between the screw and nut, resulting in a more precise and accurate motion control system.
