The BJ worm gear screw jack was created in several different versions and happens to be used in countless solutions within Healthcare, the Food Industry and other industries.
All worm gear screw jacks may because standard be given easy-to-clean and yellow chromated surfaces with stainless steel spindles and food approved lubricants.
If there are unique requirements for the look, we are pleased to offer adaptations actually in smaller quantities.
The spindles can be protected from dirt and water through the use of protecting tubes.
Ball-screw jacks include a high-effectiveness ball screw and nut that reduces the required input torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-steel screw jack are for environments where corrosion resistance is essential. Stainless-steel lifting threads are precision formed to Class 2-C (centralizing) thread profiles.
The look is compact, simple and its own modular construction allows great flexibility in the choice of gear, installation options, flanges, oil types and surface treatments. The modular style is also ideal if there is a dependence on customisations where the gearbox should be optimized for specific needs. That is the reason why we can produce worm equipment screw jacks adapted to your wishes at an attractive cost.
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 permits running more axial movements synchronously.
By connecting person 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 which a few additional styles originate. First, there are translating screw jacks. These types of screw jacks make use of a good start shaft or screw that travels into or right out of the worm gear box. The lift shaft can either protrude from the installation flange part of the gearbox or from the top side of the worm equipment container. Secondly, are rotating type screw jacks. In this style, the lift shaft remains stationary and a lifting nut moves along the lift shaft. Similar to the translating screw jacks the screw may also protrude down from the installation flange or up from the very best of the jack. To create translation of the lift shaft or nut, both configurations must be secured to avoid rotation. Where that is unfeasible, keyed screw jacks are an option.
Each model’s worm-gear-set arrangement uses an alloy-metal worm, which drives a high-strength bronze worm equipment (drive sleeve). The worm shaft is backed on antifriction tapered roller bearings with exterior seals to prevent lack of lubrication. Machine-screw jacks include a lifting shaft made of alloy steel with the very least tensile strength of 95,000 psi. Lead accuracy is approximately 0.004 in./ft.
