The BJ worm gear screw jack was created in several different versions and happens to be used in countless solutions within Healthcare, the meals Industry and other industries.
All worm gear screw jacks may since standard be supplied with easy-to-clean and yellow-colored chromated areas with stainless steel spindles and food approved lubricants.
If there are 
special requirements for the design, we are pleased 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-efficiency ball screw and nut that reduces the required input torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-metal screw jack are for conditions where corrosion level of resistance is essential. Stainless-metal lifting threads are precision shaped to Course 2-C (centralizing) thread profiles.
The design is compact, simple and its own modular construction allows great flexibility 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 in fact the gearbox should be optimized for particular needs. That is the reason why we can produce worm gear screw jacks adapted to your wants at an attractive cost.
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 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 could be solved with the standard program.
There are two basic types of screw jacks of which a few additional styles originate. 1st, there are translating screw jacks. These kinds of screw jacks use a lift shaft or screw that travels into or right out of the worm gear package. The lift shaft can either protrude from the mounting flange aspect 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 continues to be stationary and a lifting nut moves along the lift shaft. Similar to 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 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 backed on antifriction tapered roller bearings with external seals to prevent loss of lubrication. Machine-screw jacks include a lifting shaft made of alloy steel with a minimum tensile strength of 95,000 psi. Lead accuracy is approximately 0.004 in./ft.
