The BJ worm gear screw jack is designed in a number of different versions and is currently found in countless solutions within Healthcare, the meals Industry and other industries.
All worm equipment screw jacks may as standard be supplied with easy-to-clean and yellow chromated areas with stainless spindles and food approved lubricants.
If there are unique requirements for the look, we are very happy to offer adaptations also in smaller quantities.
The spindles can be protected from dirt and water through the use of 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-steel screw jack are for environments where corrosion resistance is essential. Stainless-steel lifting threads are precision created to Class 2-C (centralizing) thread profiles.
The look is compact, simple and its own modular construction allows great flexibility in the choice of gear, mounting options, flanges, oil types and surface treatments. The modular design is also ideal if there is a dependence on customisations where the gearbox must be optimized for particular needs. That's the reason why we can produce worm equipment screw jacks adapted to your wants at an attractive price.
The worm equipment screw jack allows for 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 wealthy accessories many problems can be solved with the typical program.
There are two basic types of screw jacks of which a few additional styles originate. 1st, there are translating screw jacks. These types of screw jacks use a lift shaft or screw that travels into or out from the worm gear box. The lift shaft can either protrude from the installation flange part of the gearbox or from the very best aspect of the worm equipment 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 may 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 prevent 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 backed on antifriction tapered roller bearings with external seals to prevent loss of lubrication. Machine-screw jacks feature a lifting shaft manufactured from alloy steel with a minimum tensile strength of 95,000 psi. Lead accuracy is approximately 0.004 in./ft.
