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 gear screw jacks may as standard be supplied with easy-to-clean and yellow-colored chromated areas with stainless spindles and meals approved lubricants.
If there are unique requirements for the look, 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 include a high-efficiency ball screw and nut that reduces the mandatory input torque to about one-third the torque required for machine-screw jacks. 300 Series Stainless-steel screw jack are for environments where corrosion resistance is essential. Stainless-steel lifting threads are precision created 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 treatments. The modular design is also ideal when there is a need for customisations where in fact 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 desires at an attractive cost.
The worm equipment screw jack allows for axial positioning and together with our other products within the field of encoders, couplings and connecting shafts, it allows for running more axial actions synchronously.
By connecting person screw jacks with drive shafts lifting systems could be realized in a straightforward way. With the rich accessories many problems could be solved with the typical program.
There are two basic types of screw jacks which a few additional styles originate. 1st, there are translating screw jacks. These types of screw jacks use 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 part of the gearbox or from the very best side 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 mounting flange or up from the top 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-steel worm, which drives a high-strength bronze worm equipment (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with exterior seals to prevent loss of lubrication. Machine-screw jacks include a lifting shaft made of alloy steel with a minimum tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
