The BJ worm gear screw jack is designed in several different versions and is currently found in countless solutions within Healthcare, the meals 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 meals approved lubricants.
If there are particular requirements for the look, we are very happy to offer adaptations even in smaller quantities.
The spindles could be protected from dirt and water by using protecting tubes.
Ball-screw jacks feature 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 shaped to Course 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 area treatments. The modular style is also ideal if there is a need for customisations where in fact the gearbox should be optimized for particular needs. That’s the reason why we can produce worm gear screw jacks adapted to your wants at an attractive cost.
The worm gear screw jack permits axial positioning and together with our other items within the field of encoders, couplings and connecting shafts, it allows for running more axial movements synchronously.
By connecting person screw jacks with drive shafts lifting systems can be realized in a straightforward way. With the wealthy accessories many problems could be solved with the typical program.
There are two basic types of screw jacks which a few additional styles originate. 1st, 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 very best aspect 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. Similar to the translating screw jacks the screw can also protrude down from the installation flange or up from the very best of the jack. To produce translation of the lift shaft or nut, both configurations must be secured to avoid rotation. Where that is unfeasible, keyed screw jacks are a choice.
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 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 precision is approximately 0.004 in./ft.
