The BJ worm gear screw jack was created in a number of different versions and is currently used in countless solutions within Healthcare, the meals Industry and other industries.
All worm gear screw jacks may because standard be given easy-to-clean and yellowish chromated surfaces with stainless 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 through the use of 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 environments where corrosion level of resistance is essential. Stainless-steel lifting threads are precision produced to Course 2-C (centralizing) thread profiles.
The design is compact, simple and its modular construction allows great flexibility in the choice of gear, installation options, flanges, oil types and surface area treatments. The modular style is also ideal when there is a need for customisations where in fact the gearbox must be optimized for particular needs. That is the reason why we can produce worm equipment screw jacks adapted to your wishes at an attractive cost.
The worm gear screw jack allows for axial positioning and as well as our other items 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 can be realized in a straightforward 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. First, there are translating screw jacks. These kinds of screw jacks use a lift 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 top part of the worm equipment container. Secondly, are rotating type screw jacks. In this design, the lift shaft remains stationary and a lifting nut moves along the lift shaft. Much like the translating screw jacks the screw can also protrude down from the mounting flange or up from the very best of the jack. To create translation of the lift shaft or nut, both configurations must be secured to avoid rotation. Where that is unfeasible, keyed screw jacks are a choice.
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 supported 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 accuracy is approximately 0.004 in./ft.
