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

All worm equipment screw jacks may as standard be given easy-to-clean and yellow chromated areas with stainless steel spindles and meals approved lubricants.
If there are unique requirements for the design, we are pleased to offer adaptations actually in smaller quantities.

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

Ball-screw jacks include a high-effectiveness 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 conditions where corrosion level of resistance is essential. Stainless-metal lifting threads are precision shaped to Class 2-C (centralizing) thread profiles.
The look is compact, simple and its modular construction allows great versatility in the decision of gear, installation options, flanges, oil types and surface treatments. The modular style is also ideal when there is a dependence on customisations where the gearbox should be optimized for particular needs. That’s the reason why we can produce worm equipment screw jacks adapted to your wishes at an attractive cost.
The worm equipment screw jack allows for axial positioning and as well as our other products 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 straightforward way. With the wealthy 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. 1st, there are translating screw jacks. These types of screw jacks make use of 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 part of the gearbox or from the very best side of the worm gear box. Secondly, are rotating type screw jacks. In this design, the lift shaft continues to be stationary and a lifting nut movements 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 create translation of the lift shaft or nut, both configurations must be secured to prevent 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 gear (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with exterior seals to prevent loss of lubrication. Machine-screw jacks feature a lifting shaft made of alloy steel with a minimum tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
