The BJ worm gear screw jack was created in a number of different versions and happens to be used in countless solutions within Healthcare, the meals 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 food approved lubricants.
If there are special requirements for the look, we are pleased to offer adaptations actually in smaller quantities.

The spindles can 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 required for machine-screw jacks. 300 Series Stainless-metal screw jack are for environments where corrosion resistance is essential. Stainless-steel lifting threads are precision shaped to Course 2-C (centralizing) thread profiles.
The design is compact, simple and its modular construction allows great versatility in the decision of gear, installation 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 specific needs. That is the reason why we are able to produce worm equipment screw jacks adapted to your desires at an attractive cost.
The worm equipment screw jack allows for axial positioning and as well as our other items within the field of encoders, couplings and connecting shafts, it permits running more axial actions synchronously.

By connecting person screw jacks with drive shafts lifting systems can be realized in a straightforward way. With the wealthy accessories many problems can be solved with the typical program.
There are two basic types of screw jacks which a few additional styles originate. Initial, there are translating screw jacks. These kinds of screw jacks make use of a good start shaft or screw that travels into or out from the worm gear package. The lift shaft can either protrude from the mounting flange side of the gearbox or from the top side of the worm equipment 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. Much like the translating screw jacks the screw can 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 avoid rotation. Where that is unfeasible, keyed screw jacks are a choice.
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 backed on antifriction tapered roller bearings with external seals to prevent loss of lubrication. Machine-screw jacks include a lifting shaft manufactured from alloy steel with a minimum tensile strength of 95,000 psi. Lead precision is approximately 0.004 in./ft.
