More Details

PMT Precision Rolled Ball Screw assemblies feature 25µm/300mm lead accuracy ball screws with precision ground preloaded ball nuts that are an economical, high-performance alternative to ground thread ball screw assemblies.

PMT Precision Rolled Ball Screw 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 sytem for long life.
