The BJ worm gear screw jack was created in a number of different versions and is currently found in countless solutions within Healthcare, the meals Industry and other industries.

All worm gear screw jacks may because standard be given easy-to-clean and yellowish chromated surfaces with stainless steel spindles and food approved lubricants.
If there are unique requirements for the design, we are pleased to offer adaptations actually in smaller quantities.

The spindles could 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-metal screw jack are for environments where corrosion resistance is essential. Stainless-steel lifting threads are precision produced to Class 2-C (centralizing) thread profiles.
The design is compact, simple and its modular construction allows great versatility in the choice of gear, mounting options, flanges, oil types and surface area treatments. The modular design is also ideal if there is a dependence on customisations where in fact the gearbox should be optimized for specific needs. That’s the reason why we are able to produce worm equipment screw jacks adapted to your wishes at an attractive cost.
The worm equipment screw jack permits axial positioning and as well as our other items within the field of encoders, couplings and connecting shafts, it permits running more axial movements synchronously.

By connecting individual 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 standard program.
There are two basic types of screw jacks of which a few additional styles originate. First, there are translating screw jacks. These kinds of screw jacks use a good start shaft or screw that travels into or right out of the worm gear package. The lift shaft can either protrude from the mounting flange part of the gearbox or from the top side of the worm equipment container. Secondly, are rotating type screw jacks. In this style, the lift shaft remains stationary and a lifting nut moves along the lift shaft. Similar to the translating screw jacks the screw can also protrude down from the installation 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 gear (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with external seals to prevent lack 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 around 0.004 in./ft.
