Universal Joint

A universal joint is a mechanical device that allows two shafts not in line (offset) with each other limited freedom of movement in any direction whilst transmitting rotary motion. It is an ideal form of coupling each two shafts by universal joints when offset is unavoidable in simultaneously lifting twin screw jack systems or multiple screw jack s

Flexible Jaw Coupling

JACTON Screw Jacks used alone or in multiple screw jack lifting systems arrangements require couplings to transmit power to the input shaft. JACTON provides flexible type couplings for use with screw jacks. Require no lubrication, and are resistant to oil, grease, moisture and other contaminants. Small volume and large transmitted torque. To be plu

Connecting Shafts

JACTON connecting shafts is used to interconnect the input shafts of JACTON worm gear screw jacks used in a multiple screw jack lift system arrangement. The connecting shafts transfer the torque from the motor to the screw jack or from screw jack to screw jack. Machined journals and keyways at each end, keys supplied for each end. Standard diameter

Linear Bushings and Shafts

Note 1: Running single screw jack with unguided of linear bushings and shafts or others, should be marked to JACTON sales, require anti-rotation keyed screw jacks.
Note 2: Running big sizes table top and heavy load several units screw jack lift systems, linear bushings and shafts will be recommended as the guides, to prevent the lateral force / s

Pillow Blocks

JACTON pillow blocks are important components in screw jack lift system. Pillow blocks is sometimes needed to support long connecting shafts. Pillow blocks include self-aligning replaceable bearings that are pre-lubricated. They are suitable for use under normal duty operation.

Hand Wheel

A handwheel is a convenient solution for manual operation self-locking screw jacks or self-locking lightweight screw jacks lifting systems. They are mounted directly to the jack input shafts. Can be adapted for use on self locking jacks from 2.5kn up to the 20 ton load capacity model. Handwheels are available in a range of diameters such as 80mm, 1

Aluminum Handwheel with Folding Handle

Aluminum Handwheel with Folding Handle is a convenient solution for manually operated self-locking screw jacks or screw jack system. Aluminum Handwheel directly coupled with screw jack's input worm shaft, which can be adapted to use on self locking jacks from 2.5kn up to the 20 ton load capacity model. Aluminum Handwheel are available in a range of

Electric Motor

JACTON standard motor mounts allow direct coupling to the motor shaft on either the right or the left side of the screw jacks input shafts. These assemblies are available for all screw jacks sizes. Non-standard motor mounts can be designed for special requirements including special couplings, NEMA frame motors, DIN standard motors, hydraulic motor,

Helical Gear Motor

When motorized worm gear screw jacks or screw jack lifting systems required low travel speed, but screw jacks is can not be reached with 4pole or 6pole 3-phase motor, under this conditions, it will be need 3-phase motor combined with gear reducer. JACTON uses high efficiency and high torque helical gear reducers for motorized worm gear screw jacks

Single Phase Asynchronous Motor

Single Phase Asynchronous Motor is coupled with screw jack as electric screw jack when have not 3-phase voltage. Suitable Single Phase Asynchronous Motor voltage 110V,115V,120V,220V,240V and 50Hz,60Hz frequency, Insulation class B,F, Protection class IP44, IP54, IP55 etc.
