The BJ worm gear screw jack is designed in several different versions and is currently used in countless solutions within Healthcare, the Food Industry and other industries.
All worm equipment screw jacks may because standard be supplied with easy-to-clean and yellow-colored chromated surfaces with stainless spindles and meals approved lubricants.
If there are unique requirements for the look, we are very happy 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 feature a high-performance ball screw and nut that reduces the mandatory insight torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-steel screw jack are for conditions where corrosion level of resistance is essential. Stainless-metal lifting threads are precision produced to Class 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 area treatments. The modular design is also ideal when 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 desires 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 permits running more axial motions synchronously.
By connecting individual 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. Initial, there are translating screw jacks. These kinds of screw jacks use a lift shaft or screw that travels into or out from the worm gear container. The lift shaft can either protrude from the installation flange part of the gearbox or from the very best part of the worm equipment container. Secondly, are rotating type screw jacks. In this design, the lift shaft remains stationary and a lifting nut movements along the lift shaft. Much like 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 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 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 a minimum tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
