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

All worm gear screw jacks may since standard be supplied with easy-to-clean and yellowish chromated areas with stainless steel spindles and meals approved lubricants.
If there are special 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 include a high-performance ball screw and nut that reduces the mandatory insight torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-metal screw jack are for conditions where corrosion resistance is essential. Stainless-metal lifting threads are precision produced to Class 2-C (centralizing) thread profiles.
The look is compact, simple and its own modular construction allows great versatility in the choice of gear, installation 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 is the reason why we can produce worm equipment screw jacks adapted to your wants at an attractive cost.
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 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 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 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 package. Secondly, are rotating type screw jacks. In this style, the lift shaft remains stationary and a lifting nut techniques along the lift shaft. Much like 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 avoid rotation. Where this 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 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 accuracy is approximately 0.004 in./ft.
