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 Food Industry and other industries.

All worm equipment screw jacks may because standard be supplied with easy-to-clean and yellow chromated areas with stainless steel spindles and food approved lubricants.
If there are unique requirements for the design, we are pleased 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 feature a high-effectiveness ball screw and nut that reduces the mandatory input torque to about one-third the torque required for machine-screw jacks. 300 Series Stainless-steel screw jack are for conditions where corrosion resistance is essential. Stainless-metal lifting threads are precision produced to Class 2-C (centralizing) thread profiles.
The design is compact, simple and its modular construction allows great flexibility in the choice of gear, installation options, flanges, oil types and surface treatments. The modular design is also ideal if there is a dependence on customisations where in fact the gearbox should be optimized for specific needs. That’s the reason why we are able to produce worm equipment screw jacks adapted to your wants at an attractive price.
The worm gear screw jack permits axial positioning and as well as our other items within the field of encoders, couplings and connecting shafts, it allows for running more axial movements synchronously.

By connecting person screw jacks with drive shafts lifting systems could be realized in a simple way. With the rich accessories many problems could be solved with the typical 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 good start shaft or screw that travels into or out from the worm gear container. The lift shaft can either protrude from the installation flange side of the gearbox or from the very best part of the worm equipment package. Secondly, are rotating type screw jacks. In this design, the lift shaft continues to be stationary and a lifting nut moves along the lift shaft. Much like the translating screw jacks the screw can also protrude down from the mounting flange or up from the top of the jack. To produce translation of the lift shaft or nut, both configurations should be secured to avoid 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 gear (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 the very least tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
