worm gear screw jack

The BJ worm gear screw jack is designed 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 as standard be supplied with easy-to-clean and yellow chromated areas with stainless spindles and meals approved lubricants.
If there are particular requirements for the design, we are pleased to offer adaptations actually in smaller quantities.

The spindles could be protected from dirt and water through the use of 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 environments where corrosion level of resistance is essential. Stainless-steel lifting threads are precision created to Course 2-C (centralizing) thread profiles.
The design is compact, simple and its modular construction allows great flexibility in the decision of gear, installation options, flanges, oil types and surface treatments. The modular style is also ideal when there is a need for customisations where in fact the gearbox must be optimized for specific needs. That’s the reason why we are able to produce worm equipment screw jacks adapted to your wishes at an attractive cost.
The worm gear screw jack permits axial positioning and together with 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 can be realized in a straightforward way. With the rich accessories many problems could be solved with the standard 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 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 installation flange aspect of the gearbox or from the very best part of the worm gear package. Secondly, are rotating type screw jacks. In this style, the lift shaft continues to be stationary and a lifting nut techniques along the lift shaft. Similar to the translating screw jacks the screw may also protrude down from the installation flange or up from the very best of the jack. To produce 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-metal worm, which drives a high-strength bronze worm gear (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 manufactured from alloy steel with the very least tensile strength of 95,000 psi. Lead precision is approximately 0.004 in./ft.
