worm gear screw jack

The BJ worm gear screw jack was created in a number of different versions and happens to be used in countless solutions within Healthcare, the meals Industry and other industries.

All worm equipment screw jacks may as standard be supplied with easy-to-clean and yellowish chromated areas 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 by using protecting tubes.

Ball-screw jacks feature a high-efficiency ball screw and nut that reduces the mandatory insight torque to about one-third the torque required for machine-screw jacks. 300 Series Stainless-metal screw jack are for conditions where corrosion resistance is essential. Stainless-metal lifting threads are precision created to Class 2-C (centralizing) thread profiles.
The design is compact, simple and its modular construction allows great flexibility in the choice of gear, mounting options, flanges, oil types and surface treatments. The modular style is also ideal if there is a need for customisations where in fact the gearbox must be optimized for specific needs. That is the reason why we are able to produce worm gear screw jacks adapted to your wants at an attractive cost.
The worm equipment 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 individual 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. 1st, there are translating screw jacks. These kinds of screw jacks make use of a lift shaft or screw that travels into or out from the worm gear box. The lift shaft can either protrude from the mounting flange aspect of the gearbox or from the very best side of the worm equipment box. Secondly, are rotating type screw jacks. In this design, the lift shaft remains 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 top of the jack. To create translation of the lift shaft or nut, both configurations should be secured to prevent 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 equipment (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with exterior seals to prevent lack of lubrication. Machine-screw jacks include a lifting shaft manufactured from alloy steel with a minimum tensile strength of 95,000 psi. Lead precision is approximately 0.004 in./ft.
