The BJ worm gear screw jack is designed 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 because standard be supplied with easy-to-clean and yellow chromated surfaces with stainless steel spindles and food approved lubricants.
If there are special requirements for the design, we are pleased to offer adaptations also in smaller quantities.
The spindles could be protected from dirt and water by using protecting tubes.
Ball-screw jacks feature a high-effectiveness ball screw and nut that reduces the mandatory insight torque to about one-third the torque required for machine-screw jacks. 300 Series Stainless-steel screw jack are for environments where corrosion level of resistance is essential. Stainless-steel lifting threads are precision formed to Class 2-C (centralizing) 
thread profiles.
The look is compact, simple and its modular construction allows great flexibility in the decision of gear, mounting options, flanges, oil types and surface area treatments. The modular style is also ideal when there is a dependence on customisations where in fact the gearbox should be optimized for particular needs. That’s the reason why we can produce worm equipment screw jacks adapted to your desires at an attractive cost.
The worm equipment screw jack permits axial positioning and as well as our other products within the field of encoders, couplings and connecting shafts, it permits running more axial motions synchronously.
By connecting individual 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 standard program.
There are two basic types of screw jacks which a few additional styles originate. First, there are translating screw jacks. These kinds of screw jacks use a lift shaft or screw that travels into or out from the worm gear package. The lift shaft can either protrude from the mounting flange side of the gearbox or from the top aspect of the worm gear 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. Similar to the translating screw jacks the screw can also protrude down from the mounting 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 prevent 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 gear (drive sleeve). The worm shaft is backed on antifriction tapered roller bearings with external seals to prevent lack of lubrication. Machine-screw jacks feature a lifting shaft manufactured from alloy steel with the very least tensile strength of 95,000 psi. Lead precision is approximately 0.004 in./ft.
