The BJ worm gear screw jack was created in a number of 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-colored chromated areas with stainless steel spindles and meals approved lubricants.
If there are special requirements for the look, we are pleased to offer adaptations actually in smaller quantities.
The spindles could 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 required 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 produced to Class 2-C (centralizing) thread profiles.
The look is compact, simple and its own modular construction allows great versatility in the choice of gear, mounting options, flanges, oil types and surface area treatments. The modular design is also ideal when there is a dependence on customisations where the gearbox must be optimized for particular needs. That is the reason why we can produce worm equipment screw jacks adapted to your wishes at an attractive price.
The worm gear screw jack allows for 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 person screw jacks with drive shafts lifting systems can be realized in a simple way. With the rich accessories many problems can be solved with the typical program.
There are two basic types of screw jacks 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 box. The lift shaft can either protrude from the installation flange aspect of the gearbox or from the top side of the worm gear container. Secondly, are rotating type screw jacks. In this style, the lift shaft remains stationary and a lifting nut movements along the lift shaft. Much like 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 should be secured to prevent rotation. Where that is unfeasible, keyed screw jacks are a choice.
Each model’s worm-gear-set arrangement uses an alloy-metal worm, which drives a high-strength bronze worm gear (drive sleeve). The worm shaft is backed on antifriction tapered roller bearings with external seals to prevent lack of lubrication. Machine-screw jacks feature a lifting shaft manufactured from alloy steel with the very least tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
