Description:
800KG compact bevel gear ball screw jacks (High-speed Screw jacks) are a special form of Screw jacks. They allow higher lifting speeds than the usual Screw jacks. This is made possible by a low gear reduction, stable design, optimised lubrication conditions, variable thread pitches and permissible input speeds of up to 1500 rpm. The arc-toothed, single-stage bevel gear sets are designed for high running smoothness and load capacity and thus enable smooth and stable running of the spindle with high input power.


Main Features
* Higher efficiency, higher lifting speed, higher duty cycle, longer lifespan
* Static load capacity 400 kgf. Dynamic load capacity 200 kgf. 
* Ball screw diameter 20 mm, ball screw lead 5 mm.
* There are no "standard" travel lengths.
* Upright or Inverted mounting. Available in tension or compression loads.
* Translating, Keyed for non-rotating, and Rotating designs.
* Available in 2:1 ratio. 
* Standard with single lead ball screw, custom double lead ball screw which offers increased travel speed and require a brake or external locking device to hold position.
* Ball Screw Ends: top plate, clevis end, plain end, threaded end, fork end, rod end.
* Manual operation or Motor driven are available.
* Bevel gear ball screw jacks, gear motors, bevel gearboxes, connecting shafts and couplings for dual or multiple jack arrangements.
* Optimal for low-speed operation: The driving system has less noise because machinery can be driven at a lower input speed.
* Simple and effective solution in comparison with hydraulic and pneumatic systems.

Structures and Materials
