worm gear screw jack

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

All worm equipment screw jacks may because standard be given easy-to-clean and yellow-colored chromated areas with stainless spindles and food approved lubricants.
If there are unique requirements for the design, we are very happy to offer adaptations also in smaller quantities.

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

Ball-screw jacks include 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-metal screw jack are for environments where corrosion level of resistance is essential. Stainless-metal lifting threads are precision created to Course 2-C (centralizing) thread profiles.
The look is compact, simple and its own modular construction allows great flexibility 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 in fact the gearbox must be optimized for particular needs. That is the reason why we can produce worm equipment screw jacks adapted to your desires at an attractive cost.
The worm equipment screw jack permits axial positioning and as well as our other items 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 wealthy accessories many problems could 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 kinds of screw jacks use a good start shaft or screw that travels into or out from the worm gear package. The lift shaft can either protrude from the installation flange aspect of the gearbox or from the very best side of the worm equipment package. 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 top of the jack. To create 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 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 the very least tensile strength of 95,000 psi. Lead precision is around 0.004 in./ft.
