NEFF Precision Rolled Ball Screws

NEFF Rolled Ball Screw Assemblies are designed to provide quiet, smooth running, efficient performance. They are rolled to an accuracy of ±12µm/300mm, with higher accuracies readily available upon request.  Ball nuts include one of three unique ball return systems (depending on the diameter and lead of the screw used) providing great guidance, low wear, and smooth running performance.  Ball nuts come standard with profiled nitrile butadiene rubber wipers to contain lubricant and help repel fine contaminants (dust, powder, etc.).
