Features

• Surface-treated ball screw

  As the surface treatment, low-temperature black chromium finishing is applied to the ball screw and nuts to improve corrosion resistance. The color of the surface is black. It is also possible to apply the surface treatment to shaft end fittings, the main body of the jack, etc.

  Low dust generation grease

  We offer several types of grease, including urea and fluorine series, suitable for your usage environment.

  Unified paint application

  The color of the jack’s main body is black, which is similar to the color of the surface-treated ball screw. That creates a sense of unity, making nothing stand out when the jack is assembled.
  (You can also specify the color of paint)

  Choice of driving source

  Various types of the servo motor with brakes can be mounted according to your purpose of use.
