The BJ worm gear screw jack was created in a number of different versions and is currently found in countless solutions within Healthcare, the Food Industry and other industries.

All worm gear screw jacks may since standard be given easy-to-clean and yellow chromated surfaces with stainless spindles and meals approved lubricants.
If there are unique requirements for the design, we are very happy to offer adaptations actually 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 required input torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-metal screw jack are for conditions where corrosion level of resistance is essential. Stainless-steel lifting threads are precision created to Class 2-C (centralizing) thread profiles.
The look is compact, simple and its own modular construction allows great versatility in the decision of gear, installation options, flanges, oil types and surface treatments. The modular style is also ideal when there is a dependence on customisations where the gearbox must be optimized for particular needs. That’s the reason why we are able to produce worm gear screw jacks adapted to your wants at an attractive cost.
The worm gear screw jack allows for axial positioning and as well as our other products within the field of encoders, couplings and connecting shafts, it permits running more axial actions 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 standard program.
There are two basic types of screw jacks which a few additional styles originate. First, 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 box. The lift shaft can either protrude from the mounting flange aspect of the gearbox or from the very best side of the worm gear container. Secondly, are rotating type screw jacks. In this style, the lift shaft continues to be stationary and a lifting nut moves 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 this 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 backed on antifriction tapered roller bearings with exterior seals to prevent lack of lubrication. Machine-screw jacks feature a lifting shaft made of alloy steel with the very least tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
