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 particular requirements for the design, we are very happy to offer adaptations actually in smaller quantities.

The spindles can 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 required insight torque to about one-third the torque necessary for machine-screw jacks. 300 Series Stainless-steel screw jack are for environments where corrosion level of resistance is essential. Stainless-metal lifting threads are precision shaped to Course 2-C (centralizing) thread profiles.
The design 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 design is also ideal when there is a dependence on customisations where the gearbox should be optimized for particular needs. That is the reason why we are able to produce worm equipment screw jacks adapted to your wants 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 permits running more axial movements 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 typical 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 make use of a good start 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 top aspect of the worm equipment box. Secondly, are rotating type screw jacks. In this design, the lift shaft continues to be stationary and a lifting nut techniques 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 must be secured to avoid 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 equipment (drive sleeve). The worm shaft is supported on antifriction tapered roller bearings with external seals to prevent loss of lubrication. Machine-screw jacks include a lifting shaft manufactured from alloy steel with a minimum tensile strength of 95,000 psi. Lead precision is approximately 0.004 in./ft.
