The BJ worm gear screw jack is designed in several different versions and happens to be used in countless solutions within Healthcare, the Food Industry and other industries.
All worm equipment screw jacks may as 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 even in smaller quantities.
The spindles can be protected from dirt and water through the use of protecting tubes.
Ball-screw jacks feature a high-effectiveness ball screw and nut that reduces the mandatory input torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-steel screw jack are for environments where corrosion level of resistance is essential. Stainless-metal lifting threads are precision created to Course 2-C (centralizing) thread profiles.
The look is compact, simple and its modular construction allows great versatility in the decision of gear, installation options, flanges, oil types and surface area treatments. The modular design is also ideal if there is a dependence on customisations where the gearbox must be optimized for particular needs. That is the reason why we are able to produce worm gear screw jacks adapted to your wishes at an attractive cost.
The worm equipment screw jack permits axial positioning and together with 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 simple way. With the wealthy accessories many problems could be solved with the typical program.
There are two basic types of screw jacks of which a few additional styles originate. First, there are translating screw jacks. These kinds of screw jacks make use of a lift shaft or screw that travels into or right out of the worm gear package. The lift shaft can either protrude from the installation flange aspect of the gearbox or from the top part of the worm gear package. Secondly, are rotating type screw jacks. 
In this design, the lift shaft continues to be stationary and a lifting nut moves along the lift shaft. Similar to the translating screw jacks the screw may also protrude down from the mounting 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 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 gear (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 manufactured from alloy steel with the very least tensile strength of 95,000 psi. Lead accuracy is approximately 0.004 in./ft.
