Metric Precision Accuracy Ball Screw Assembly Features

PMT metric precision accuracy rolled ball screw assemblies feature 25┬Ám/300mm lead accuracy ball screws with precision ground preloaded ball nuts that are an economical, high-performance alternative to ground thread ball screw assemblies.

The PMT metric precision accuracy ball screw assemblies are manufactured under tightly controlled conditions in the rolling process. Uniform heat treatment is monitored by temperature sensors to ensure high quality and accurate lead. The preloaded ball nut assemblies ensure accuracy, zero backlash, consistent repeatability, and high system stiffness at low running torque.

Ball nuts feature a unique solid preload that enhances system smoothness, and are factory-fit on the ball screws, providing a backlash-free system for long life.
