Precision jacks for lifting and
actuation
High quality jacks are thoroughly tested and environmentally engineered to ensure consistent high performance and safety for the user.
Tsubaki UK has a new range of high quality, high precision power jacks for lifting and actuation tasks in all areas of industry and commerce The comprehensive Linipower range, with three model types, and supported by a wide range of options and accessories, delivers solutions in key sectors such as medical, industrial, transport, liquid crystal/PDP manufacture, telecommunications and entertainment, providing constant high performance, precision and reliability even under demanding application conditions
The Linipower jacks are the result of cutting-edge technology developed by Tsubaki's Emerson division; acquired through years of experience as a leading manufacturer of electromechanical actuators.
They are high quality units that are thoroughly tested and environmentally engineered to ensure consistent high performance and safety for the user.
Robust in design, the Linipower jacks offer lift capabilities in the range 1.96 to 980kN; strokes to 2m; and the flexibility to be installed horizontally, vertically or inclined.
They can be supplied as individual items, or as motorised systems employing matched standard or specialised gearmotors, space-saving hypoid motors or servomotors.
The jacks also offer the user options such as an LD function for excellent low dust performance, and safety caps to protect personnel from possible injuries.
The standard base model in the Linipower range is the JWM series, a simple, compact and affordable machine screw jack that integrates a trapezoidal screw and high precision worm gear, making it highly suitable for low speed, low frequency operations.
The unique sliding motion of the trapezoidal screw provides smooth and consistent low speed performance, while an integrated Self-Lock feature maintains load, obviating the cost and time of installing a brake unit in the majority of applications.
Offering the highest capacity (908kN) in the Linipower range, the JWB ballscrew type jack is a highly efficient unit for high speed, high frequency operations.
The compact drive produces high power, while its ball screw technology delivers long and predictable life, and also high efficiency, which, when compared with the JWM, allows a higher speed drive.
For applications where speed rather than lift capacity is the major requirement, the Linipower range offers the JWH high lead ball screw type jack.
Depending on the lead used, the screw shaft speed of the JWH jack can exceed that of a JWB by up to 4x, at the same input shaft rev/min; reaching maximum screw shaft speeds of up of 7.5m/min.
Importantly, despite its higher speed performance, the JWH is actually quieter than the JWB jack, as it requires less input rev/min at its drive and reducer units to run at the same speed.
Completing the Linipower range is the LD (low dust) type jack, which is an excellent choice for use in clean rooms such as those serving FDP (liquid crystal/PDP) manufacture, and bearing assembly.
This model regulates dust generation resulting from wear, as well as dust produced from the screw.
Factory tested for dust volume, the LD jack is highly reliable for clean room operation.
Complementing the Linipower jacks, and widening their range of application, is a comprehensive list of options.
These include: IP55 sealed motors; stroke control devices; brakes; bellows; position sensors; limit switches and LS counters; potentiometers that allow full adjustment of stroke; rotary encoders that enable users to control the jack stroke; clevis and trunnion mounting adapters; hand wheels and columns for manual operation; and Tsubaki's high performance Emer-Flex and Jaw-Flex couplings, which aid installation and enhance system reliability.
