The BJ worm gear screw jack was created in several different versions and happens to be found in countless solutions within Healthcare, the meals Industry and other industries.
All worm equipment screw jacks may since standard be supplied with easy-to-clean and yellow-colored 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 could be protected from dirt and water by using protecting tubes.
Ball-screw jacks include 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-steel screw jack are for conditions where corrosion level of resistance is essential. Stainless-steel lifting threads are precision produced to Class 2-C (centralizing) thread profiles.
The look is compact, simple and its own modular construction allows great flexibility in the decision of gear, mounting options, flanges, oil types and surface treatments. The modular design is also ideal if there is a dependence on customisations where the gearbox should 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 cost.
The worm gear screw jack permits axial positioning and together with our other items within the field of encoders, couplings and connecting shafts, it permits running more axial motions synchronously.
By connecting person screw jacks with drive shafts lifting systems can be realized in a straightforward way. With the rich accessories many problems could be solved with the standard program.
There are two basic types of screw jacks which a few additional styles originate. 1st, there are translating screw jacks. These kinds of screw jacks use 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 installation flange side of the gearbox or from the top part of the worm gear package. Secondly, are rotating type screw jacks. In this design, the lift shaft remains stationary and a lifting nut moves along the lift shaft. Similar to 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 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 equipment (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with external seals to prevent lack of lubrication. Machine-screw jacks feature a lifting shaft made of alloy steel with the very least tensile strength of 95,000 psi. Lead precision is approximately 0.004 in./ft.
