SFI series delivers high smoothness, high rigidity and high durability. With strong dust-proof design, SFNI & SFI series prevents abnormal chips getting into the nut extending service life, making SFNI & SFI series applicable to contaminative environment.

  • High reliability: TBI Motion applies stringent quality control standards, which realize trouble-free operation for an extended period of time.
  • Smooth operation: the high efficiency of ball screw is vastly superior than conventional screws. It takes less than 30% torque to make the linear motion into rotary motion.
  • High Durability: TBI Motion rigidly selected materials, intensive heat treating and processing techniques, have resulted in the most durable ball screws manufactured.
