The BJ worm gear screw jack is designed 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 because standard be supplied with easy-to-clean and yellow chromated surfaces with stainless 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 can be protected from dirt and water through the use of protecting tubes.

Ball-screw jacks feature a high-performance ball screw and nut that reduces the required 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-steel lifting threads are precision created to Class 2-C (centralizing) thread profiles.
The design 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 is the reason why we are able to produce worm equipment screw jacks adapted to your wishes at an attractive price.
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 permits running more axial movements synchronously.

By connecting person screw jacks with drive shafts lifting systems can 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 which a few additional styles originate. Initial, there are translating screw jacks. These types of screw jacks use a lift shaft or screw that travels into or right out of the worm gear package. The lift shaft can either protrude from the installation flange aspect of the gearbox or from the top side of the worm gear box. Secondly, are rotating type screw jacks. In this style, 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 produce translation of the lift shaft or nut, both configurations must 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 gear (drive sleeve). The worm shaft is backed on antifriction tapered roller bearings with exterior seals to prevent lack of lubrication. Machine-screw jacks include a lifting shaft made of alloy steel with a minimum tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
