The BJ worm gear screw jack is designed in several different versions and is currently used in countless solutions within Healthcare, the Food Industry and other industries.
All worm equipment screw jacks may because standard be given easy-to-clean and yellow-colored chromated areas with stainless steel spindles and food approved lubricants.
If there are particular requirements for the design, we are pleased to offer adaptations also in smaller quantities.
The spindles can be protected from dirt and water by using 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 shaped to Course 2-C (centralizing) thread profiles.
The look is compact, simple and its modular construction allows great flexibility in the decision of gear, installation options, flanges, oil types and surface treatments. The modular style is also ideal when there is a need for customisations where in fact the gearbox must be optimized for specific needs. That is the reason why we can produce worm gear screw jacks adapted to your wishes at an attractive price.
The worm gear screw jack permits axial positioning and together with 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 could 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 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 out from the worm gear package. The lift shaft can either protrude from the mounting flange side of the gearbox or from the very best part of the worm gear container. Secondly, are rotating type screw jacks. In this design, the lift shaft continues to be stationary and a lifting nut moves along the lift shaft. Similar to the translating screw jacks the screw may 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 prevent rotation. Where this 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 backed on antifriction tapered roller bearings with external seals to prevent lack of lubrication. Machine-screw jacks include 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.
