Ball Screws & Ball Nuts
New!
RBS R10, R20, R30, R37, R40, and R44 series ball screws pair hardened steel screws with compatible recirculating ball nuts for custom linear-motion assemblies requiring efficient rotary-to-linear conversion. Six screw sizes, several leads, and multiple end-preparation styles allow selection around load, travel rate, bearing support, and machining requirements.
- 24-, 48-, and 72-inch screw lengths support different machine-axis travel requirements before custom cutting or installation
- Plain, 2A, and 5A end configurations allow selection between unmachined and prepared bearing or drive ends
- Ball nut and wiper choices allow the screw assembly to be configured around load support and contamination protection

Ball Screws & Ball Nuts Accessories
New!
Ball screw and ball nut accessories provide the support, mounting, and contamination-control components needed to integrate RBS screw assemblies into custom axes. Bearing mounts establish end support, flanges connect ball nuts to the moving member, and wiper or protective components help control contamination where exposed screw threads operate in less-protected machinery.
- Select bearing-support components to match the screw end preparation and required support arrangement
- Ball nut flanges provide a mounting interface between the nut and the moving machine member
- Wipers provide additional contamination protection where debris can reach the ball screw assembly
