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

All worm equipment screw jacks may as 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 look, 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 mandatory insight torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-steel screw jack are for environments where corrosion resistance is essential. Stainless-steel lifting threads are precision formed to Course 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 need for customisations where in fact the gearbox must be optimized for particular needs. That is the reason why we can produce worm gear screw jacks adapted to your desires at an attractive price.
The worm gear screw jack allows for axial positioning and as well as our other products within the field of encoders, couplings and connecting shafts, it allows for running more axial actions synchronously.

By connecting individual screw jacks with drive shafts lifting systems can be realized in a simple way. With the rich accessories many problems can be solved with the typical 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 make use of a lift shaft or screw that travels into or right out of the worm gear container. The lift shaft can either protrude from the mounting flange aspect of the gearbox or from the top aspect of the worm equipment package. Secondly, are rotating type screw jacks. In this style, the lift shaft remains 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 top 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 an option.
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 backed 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 the very least tensile strength of 95,000 psi. Lead accuracy is around 0.004 in./ft.
