The BJ worm gear screw jack is designed in several different versions and happens to be used in countless solutions within Healthcare, the Food Industry and other industries.

All worm equipment screw jacks may since standard be given easy-to-clean and yellowish chromated surfaces with stainless steel spindles and meals approved lubricants.
If there are particular requirements for the look, we are pleased to offer adaptations actually in smaller quantities.

The spindles could 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 insight torque to about one-third the torque required 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 formed to Course 2-C (centralizing) thread profiles.
The design is compact, simple and its modular construction allows great flexibility in the choice of gear, installation options, flanges, oil types and surface area treatments. The modular design is also ideal if there is a dependence on customisations where the gearbox should be optimized for particular needs. That’s the reason why we are able to produce worm gear screw jacks adapted to your wishes at an attractive price.
The worm equipment screw jack allows for axial positioning and together with our other items within the field of encoders, couplings and connecting shafts, it allows for 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 typical 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 good start shaft or screw that travels into or out from the worm gear box. The lift shaft can either protrude from the installation flange aspect of the gearbox or from the very best side of the worm gear box. Secondly, are rotating type screw jacks. In this design, the lift shaft remains stationary and a lifting nut techniques along the lift shaft. Similar to the translating screw jacks the screw can 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 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 gear (drive sleeve). The worm shaft is supported 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 the very least tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
