worm gear screw jack

The BJ worm gear screw jack is designed in a number of different versions and happens to be found 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 yellow-colored chromated areas with stainless steel spindles and meals approved lubricants.
If there are unique requirements for the look, we are very happy to offer adaptations even in smaller quantities.

The spindles can be protected from dirt and water by using protecting tubes.

Ball-screw jacks include a high-effectiveness ball screw and nut that reduces the mandatory insight torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-metal screw jack are for environments where corrosion level of resistance is essential. Stainless-steel lifting threads are precision formed to Course 2-C (centralizing) thread profiles.
The look is compact, simple and its modular construction allows great versatility in the decision of gear, mounting options, flanges, oil types and surface treatments. The modular style is also ideal when there is a need for customisations where the gearbox should 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 price.
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 permits running more axial movements synchronously.

By connecting individual screw jacks with drive shafts lifting systems could be realized in a simple 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 types of screw jacks make use of a lift shaft or screw that travels into or right out of the worm gear box. The lift shaft can either protrude from the mounting flange side of the gearbox or from the top aspect of the worm gear box. Secondly, are rotating type screw jacks. In this style, the lift shaft remains stationary and a lifting nut movements along the lift shaft. Similar to the translating screw jacks the screw can also protrude down from the mounting 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 avoid 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 equipment (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 a minimum tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
