| The decision to use a bevel gear ball screw jack or a bevel gear machine screw jack is based on the application. For many applications, a ball screw model is the best choice. Bevel gear ball screw jacks are more efficient and therefore require less power than a bevel gear machine screw jack in the same application. For low duty cycle applications, for hand-operated applications, or if back driving is not acceptable consider a bevel gear machine screw jack. Bevel Gear Ball Screw Jacks are preferred for Long travel lengths, Long, predictable life, High duty cycles, and Oscillating motion. Bevel Gear Machine Screw Jacks are preferred for Vibration environments, Manual operation, and High static loads. | |||||||||

Product Description
Bevel Gear Ball Screw Jack 800kg-20x5-Ball Screw-Aluminum housing. Bevel Gear Ball Screw Jacks use a ball screw and nut made from hardened alloy steel with hardened bearing balls carrying the load between the nut and the screw permitting smooth and efficient movement of the load. Because of the greater efficiency and rolling action, the ball screw can operate at higher speeds or increased duty cycle when compared with the Machine Screw Jack. The addition of a high efficiency ball screw and nut reduces the required input torque to approximately one-third the torque required for the Machine Screw Jack.
Main Features
* Equipped with hardened spiral toothed bevel gear transmissions for high lifting speeds, greater duty cycles, high efficiency and long lifespan.
* Available in single shaft, two shaft and three shaft configurations. In two and three shaft configurations, the jack offers right angle characteristics with the ability to divide input power or torque, sending it equally in different directions.
* Maximum static load capacity 800 kg. Maximum dynamic load capacity 500 kg.
* High precision ball screw sizes 20x5, precise positioning, and uniform speed.
* Reduction gear ratio: 2:1. Travel 2.5 mm per turn of input shaft.
* There are no "standard" travel lengths and each bevel gear jack is built to specification, maximum stroke 800 mm in compression load, 1500 mm in tension load.
* Basic designs: Translating screw, Anti-rotation screw, and Rotating screw.
* Upright or Inverted mounting. Available in tension or compression loads.
* Standard with single lead ball screw, custom double or high lead ball screw which offers increased travel speed and require a brake or external locking device to hold position.
* Screw end fittings: top plate, clevis end, threaded end, plain end, fork head and rod end.
* Power source: electrically by brake motor driven.
* Easy synchronized operation: System design such as the simultaneous operation of multiple jacks is easy.
* Optimal for low-speed operation: The driving system has less noise because machinery can be driven at a lower input speed.
* Higher efficiency, higher lifting speed, higher duty cycle, longer lifespan
* Simple and effective solution in comparison with hydraulic and pneumatic systems.
