    Samyang Reducer Worm Gear Screw Jack SJ-T Series, Traveling Nut Type (1 to 30 tonf)

    Samyang Reducer Worm Gear Screw Jack SJ-T Series, Traveling Nut Type (1 to 30 tonf)

    Worm gear screw jacks in traveling nut design, where the screw rotates and a nut travels along it.

    Key features

    • The jack body stays fixed and only the nut moves, which saves space for long strokes
    • Available in upright and inverted mounting with high (H) and low (L) worm ratios
    • Base ratings are the same as the corresponding traveling shaft SJ sizes
