For more parameters, please consult us. Accessories include tooth-depth device, anti-rotation device, safety nut, dust shield, and magnetic induction limit switch.

1.1Normal Type (US, DS)

The nut runs and guide screw move up and down

US :Up rise   DS :Drop

Pls select US or DS according to the load and mounting position

Anti-rotation measures must be taken to prevent the rotating tendency occurred during screw shaft elevating

1.2Anti-rotation Device

UM :Up rise   DM: drop

Screw with no rotation , only travel up and down

Pls select UM or DM according to the load and mounting position

1.3Travelling Nut

In general, screw jack need enough space for screw’s travelling journey and dust hood. Using travelling nut can help jack realize longer travelling journey in limited space. The top end fittings are column, it can be a supporting point for a good transmission effect when a long travelling journey is selected.

UR : Up rise DR : Drop

Pls select UM or DM according to the load and mounting position.

Note : pls inform us the nut installation direction when selecting the types.
