The BJ worm gear screw jack was created in a number of different versions and is currently found in countless solutions within Healthcare, the Food Industry and other industries.
All worm equipment screw jacks may since standard be given easy-to-clean and yellow-colored chromated surfaces with stainless spindles and meals approved lubricants.
If there are unique requirements for the look, we are pleased to offer adaptations even in smaller quantities.
The spindles can be protected from dirt and water by using protecting tubes.
Ball-screw jacks include a high-efficiency ball screw and nut that reduces the mandatory insight torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-steel screw jack are for conditions where corrosion level of resistance is essential. Stainless-metal lifting threads are precision shaped to Class 2-C (centralizing) thread profiles.
The design is compact, simple and its own modular construction allows great flexibility in the choice of gear, mounting options, flanges, oil types and surface area treatments. The modular style is also ideal if there is a dependence on customisations where in fact the gearbox should be optimized for specific needs. That’s the reason why we can produce worm gear screw jacks adapted to your wishes at an attractive price.
The worm gear screw jack permits axial positioning and as well as our other items within the field of encoders, couplings and connecting shafts, it allows for running more axial motions synchronously.
By connecting individual screw jacks with drive shafts lifting systems could be realized in a straightforward way. With the wealthy accessories many problems could be solved with the standard program.
There are two basic types of screw jacks of which a few additional styles originate. Initial, there are translating screw jacks. These kinds of screw jacks make use of a lift shaft or screw that travels into or out from the worm gear package. The lift shaft can either protrude from the installation flange part of the gearbox or from the very best side of the worm gear container. Secondly, are rotating type screw jacks. In this design, the lift shaft remains stationary and a lifting nut techniques along the lift shaft. Much like the translating screw jacks the screw may also protrude down from the mounting flange or up from the top of the jack. To produce translation of the lift shaft or nut, both configurations 
should be secured to prevent rotation. Where this is unfeasible, keyed screw jacks are an option.
Each model’s worm-gear-set arrangement uses an alloy-steel worm, which drives a high-strength bronze worm equipment (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with exterior seals to prevent loss of lubrication. Machine-screw jacks include a lifting shaft manufactured from alloy steel with the very least tensile strength of 95,000 psi. Lead accuracy is around 0.004 in./ft.
