Pillow block is used for long connecting shaft for screw jack system.

Worm gear screw jacks not only can be used by single unit, but also can be used by multiple units. Multiple screw jacks can make up to a screw jack system together with spiral bevel gearbox,connecting shafts, couplings and motor etc.

when hydraulic, pneumatic or chain systems are prohibitive choices. These jacking system arrangements or configurations can be built in many formats with the use of bevel gearboxes, motors, reduction gearboxes, drive shafts, couplings, plummer blocks and motion control devices. Four of the most popular system configurations are the ‘H’, ‘U’, ‘T’ and ‘I’ configured jacking systems. Note that multiple screw jacks can be linked together mechanically or electrically. The latter is useful if there is no space for linking drive shafts. A screw jack system is where more than one screw jack is operated in unison to achieve a linear movement. The screw jack system arrangement is also commonly referred to as a “screw jacking system”.
