PMI Ballscrews are critical components used in precision machinery. They are manufactured by PMI Precision Motion Industries, Inc., a company established in 1990. Here are some key features of PMI Ballscrews:

  1. High Reliability: PMI manages the entire production sequence, from order receipt to delivery. This systematic approach ensures the reliability of PMI Ballscrews.
  2. High Accuracy: PMI Ballscrews undergo machining, grinding, assembly, and quality control inspection under constant temperature control (20°C). This process ensures precise performance.
  3. Long Durability: Made from German alloy steels, PMI Ballscrews are quenched, tempered, and surface-hardened for rigidity and durability.
  4. High Working Efficiency: Unlike traditional ACME screws, which rely on friction sliding, PMI Ballscrews rotate inside the nut, offering higher efficiency with only 1/3 of the driving torque.
  5. No Backlash and High Rigidity: PMI uses a Gothic profile, optimizing ball-to-groove contact. Proper preload eliminates clearance, resulting in better rigidity and accuracy1.
