More Details

MRT Rolled Ball Screw assemblies feature 100µm / 300mm lead accuracy ball screws with precision ball nuts that are an economical, high-performance alternative to ground thread ball screw assemblies. The ball nut assemblies ensure accuracy, consistent repeatability, and high system stiffness at low running torque.

Metric Ball nuts can be assembled with a selective fit to minimize lash. Nook Industries provides quality end machining of the rolled ball screw to standard configurations or to your specifications. Precision rolled ball screw assemblies may be fitted to Nook Ezze Mounts for simple system integration.
