worm gear screw jack

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

All worm equipment screw jacks may because standard be given easy-to-clean and yellow-colored chromated surfaces with stainless steel spindles and food approved lubricants.
If there are special requirements for the design, we are very happy 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 environments where corrosion resistance is essential. Stainless-metal lifting threads are precision created to Course 2-C (centralizing) thread profiles.
The design is compact, simple and its own modular construction allows great versatility in the decision of gear, installation options, flanges, oil types and surface treatments. The modular design is also ideal when there is a dependence on customisations where in fact the gearbox must be optimized for specific needs. That’s the reason why we are able to produce worm gear screw jacks adapted to your desires at an attractive cost.
The worm gear screw jack permits axial positioning and together with our other products 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 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. Initial, there are translating screw jacks. These kinds of screw jacks make use of a good start shaft or screw that travels into or right out of the worm gear container. The lift shaft can either protrude from the mounting flange part of the gearbox or from the very best aspect of the worm equipment container. Secondly, are rotating type screw jacks. In this design, the lift shaft remains 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 produce 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-metal 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 a minimum tensile strength of 95,000 psi. Lead accuracy is approximately 0.004 in./ft.
