Worm Gear Ball Screw Jacks

Ball Screw Jacks - 1/4 Ton to 100 Ton & 5 kN to 200 kN

ActionJac™ Inch or Metric Worm Gear Ball Screw Jacks use a ball screw and nut made from hardened alloy steel with hardened bearing balls carrying the load between nut and screw. This rolling action reduces friction between the nut and the screw permitting smooth and efficient movement of the load. Because of the greater efficiency and rolling action, the ball screw can operate at higher speeds or increased duty cycle when compared with the Machine Screw Jack.

The addition of a high efficiency ball screw and nut reduces the required input torque to approximately one-third the torque required for the Machine Screw Jack.

Depending on size, ball screw jack designs are available with optional accessories such as boots, motor mounts, right-angle reducers, motors, encoders and rotary limit switches.

Available Finishes: Standard Nook Epoxy, Nook Outdoor, Nook Marine (Can also paint to customer specification)

Inch

Upright

A lift shaft moves through the gear box and extends out from the top. Integrated nut and worm gear for synchronized rotation. When the lift shaft is held to prevent rotation, it moves linearly through the gear box to move the load.

Inverted

A lift shaft moves a nut as it turns and is fixed to the worm gear and extends out the bottom of the jack. The load (attached to travel nut), moves along the lift shaft. 

 

Upright Rotating

A lift shaft extends out of the top of the jack and moves a nut as it turns while being fixed to the worm gear. This causes the load (attached to travel nut) to move along the lift shaft. 

Inverted Rotating

A lift shaft moves a nut as it turns while being fixed to the worm gear. This causes the load (attached to travel nut) to move along the lift shaft. The lift shaft extends out the bottom of the jack.

Double Clevis

Moves a load through an arc, such as tracking antennas, hinged doors or air dampers. One clevis is mounted on the end of the lift shaft and the other clevis is welded to a heavy duty stem cover, which is welded to the housing.

Upright Keyed

Prevents rotation of the lift shaft with a square guide attached to the screw translating inside a square stem cover. The square stem tube is supplied with lube fittings. A lift shaft moves through the gear box and extends out from the top. An integrated nut and worm gear rotate together. When the lift shaft is held to prevent rotation, it moves linearly through the gear box to move the load.

Inverted Keyed

Prevents rotation of the lift shaft with a square guide attached to the screw translating inside a square stem cover. The square stem tube is supplied with lube fittings. A lift shaft moves through the gear box and extends out from the bottom. An integrated nut and worm gear rotate together. When the lift shaft is held to prevent rotation, it moves linearly through the gear box to move the load.
