worm gear screw jack

The BJ worm gear screw jack is designed 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 since standard be given easy-to-clean and yellow-colored chromated surfaces with stainless spindles and meals approved lubricants.
If there are particular requirements for the design, we are very happy to offer adaptations also in smaller quantities.

The spindles could be protected from dirt and water through the use of protecting tubes.

Ball-screw jacks include a high-efficiency 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 resistance is essential. Stainless-metal lifting threads are precision produced 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 area treatments. The modular style is also ideal when there is a dependence on customisations where the gearbox must be optimized for particular needs. That is the reason why we can produce worm gear screw jacks adapted to your desires at an attractive cost.
The worm equipment screw jack permits 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 can be realized in a simple way. With the rich accessories many problems can be solved with the standard 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 make use of a lift shaft or screw that travels into or out from the worm gear container. The lift shaft can either protrude from the mounting flange side of the gearbox or from the top aspect of the worm gear container. 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 installation 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 an option.
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 exterior seals to prevent loss of lubrication. Machine-screw jacks feature a lifting shaft manufactured from alloy steel with a minimum tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
