The BJ worm gear screw jack is designed in several different versions and is currently used in countless solutions within Healthcare, the meals Industry and other industries.
All worm equipment screw jacks may because standard be supplied 
with easy-to-clean and yellow chromated surfaces with stainless steel spindles and food approved lubricants.
If there are special requirements for the look, we are pleased to offer adaptations even in smaller quantities.
The spindles could be protected from dirt and water through the use of protecting tubes.
Ball-screw jacks include a high-performance ball screw and nut that reduces the mandatory input torque to about one-third the torque required for machine-screw jacks. 300 Series Stainless-metal screw jack are for conditions where corrosion level of resistance is essential. Stainless-steel lifting threads are precision shaped to Course 2-C (centralizing) thread profiles.
The design is compact, simple and its own modular construction allows great versatility in the choice of gear, installation options, flanges, oil types and surface treatments. The modular design is also ideal if there is a need for customisations where in fact the gearbox should be optimized for particular needs. That is the reason why we are able to produce worm equipment screw jacks adapted to your wishes at an attractive price.
The worm gear screw jack allows for 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 can be realized in a simple way. With the rich accessories many problems can be solved with the standard program.
There are two basic types of screw jacks which a few additional styles originate. 1st, there are translating screw jacks. These types of screw jacks make use of a lift shaft or screw that travels into or out from the worm gear container. The lift shaft can either protrude from the mounting flange side of the gearbox or from the very best aspect 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. Similar to the translating screw jacks the screw can also protrude down from the installation flange or up from the top 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 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 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 a minimum tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
