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

All worm gear 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 very happy to offer adaptations also in smaller quantities.

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

Ball-screw jacks include a high-efficiency ball screw and nut that reduces the mandatory input 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 created to Course 2-C (centralizing) thread profiles.
The look is compact, simple and its modular construction allows great flexibility in the choice of gear, installation 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 particular needs. That’s the reason why we are able to produce worm gear screw jacks adapted to your wishes at an attractive price.
The worm gear screw jack allows for axial positioning and as well as our other items within the field of encoders, couplings and connecting shafts, it allows for running more axial motions 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 which a few additional styles originate. First, there are translating screw jacks. These types of screw jacks make use of a good start shaft or screw that travels into or out from the worm gear box. The lift shaft can either protrude from the mounting flange aspect of the gearbox or from the top side of the worm equipment package. 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. Much like the translating screw jacks the screw can 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 must 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-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 include a lifting shaft made of alloy steel with a minimum tensile strength of 95,000 psi. Lead accuracy is approximately 0.004 in./ft.
