The BJ worm gear screw jack is designed in a number of different versions and happens to be found in countless solutions within Healthcare, the meals Industry and other industries.
All worm gear screw jacks may as standard be supplied with easy-to-clean and yellow-colored chromated surfaces with stainless spindles and food approved lubricants.
If there are special requirements for the design, we are very happy to offer adaptations actually in smaller quantities.
The spindles can be protected from dirt and water by using protecting tubes.
Ball-screw jacks feature a high-performance ball screw and nut that reduces the required 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-steel lifting threads are precision shaped to Course 2-C (centralizing) thread profiles.
The look is compact, simple and its modular construction allows great versatility in the choice of gear, mounting options, flanges, oil types and surface area treatments. The modular style is also ideal if there is a dependence on customisations where in fact the gearbox should be optimized for 
specific needs. That is the reason why we are able to produce worm gear screw jacks adapted to your desires at an attractive cost.
The worm equipment screw jack permits axial positioning and as well as our other items within the field of encoders, couplings and connecting shafts, it permits running more axial actions synchronously.
By connecting individual screw jacks with drive shafts lifting systems could 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. Initial, there are translating screw jacks. These kinds 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 installation flange aspect of the gearbox or from the top part of the worm gear box. Secondly, are rotating type screw jacks. In this style, the lift shaft continues to be stationary and a lifting nut movements along the lift shaft. Much like the translating screw jacks the screw can 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 should be secured to avoid rotation. Where that is unfeasible, keyed screw jacks are an option.
Each model’s worm-gear-set arrangement uses an alloy-metal 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.
