The BJ worm gear screw jack was created in a number of different versions and is currently used in countless solutions within Healthcare, the Food Industry and other industries.
All worm gear 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 design, we are very happy to offer adaptations even in smaller quantities.
The spindles can 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 required insight torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-metal screw jack are for conditions where corrosion resistance is essential. Stainless-steel lifting threads are precision produced 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 when there is a dependence on customisations where in fact the gearbox must be optimized for specific needs. That’s the reason why we can 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 products 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 could 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 of which a few additional styles originate. Initial, there are translating screw jacks. These kinds of screw jacks use a good start shaft or screw that travels into or out from the worm gear package. The lift shaft can either protrude from the installation flange side of the gearbox or from the top side of the worm equipment box. 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. Much like the translating screw jacks the screw may also protrude down from the mounting 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 avoid rotation. Where this 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 gear (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with external seals to prevent lack of lubrication. Machine-screw jacks feature a lifting shaft made of alloy steel with the very least tensile strength of 95,000 psi. Lead accuracy is around 0.004 in./ft.
