The BJ worm gear screw jack was created 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 yellow-colored chromated surfaces with stainless spindles and meals approved lubricants.
If there are unique requirements for the look, we are very happy to offer adaptations even in smaller quantities.

The spindles can be protected from dirt and water by using protecting tubes.

Ball-screw jacks feature a high-effectiveness ball screw and nut that reduces the required input torque to about one-third the torque required for machine-screw jacks. 300 Series Stainless-metal screw jack are for environments where corrosion resistance is essential. Stainless-metal lifting threads are precision shaped to Class 2-C (centralizing) thread profiles.
The look is compact, simple and its own modular construction allows great flexibility in the decision of gear, mounting options, flanges, oil types and surface area treatments. The modular style is also ideal if there is a need for customisations where the gearbox must be optimized for specific needs. That is the reason why we are able to produce worm gear screw jacks adapted to your wants at an attractive cost.
The worm equipment screw jack permits axial positioning and together with our other products 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 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 lift shaft or screw that travels into or out from the worm gear container. The lift shaft can either protrude from the installation flange part of the gearbox or from the very best side of the worm equipment container. Secondly, are rotating type screw jacks. In this style, the lift shaft continues to be stationary and a lifting nut techniques along the lift shaft. Similar to the translating screw jacks the screw may also protrude down from the mounting flange or up from the top of the jack. To produce translation of the lift shaft or nut, both configurations should be secured to prevent rotation. Where this 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 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 around 0.004 in./ft.
