Product Description

Worm Gear Screw Jacks vs. Bevel Gear Screw Jacks. How To Select The Correct Types Screw Jacks For Your Application? When faced with the need to lift, lower, push or pull a load-especially a heavy load-and hold it in the correct position, a screw jack or multiple jacking system may provide the best linear motion solution when considering its performance and cost ratio. There are two main types of screw jacks: Worm Gear Screw Jacks, and Bevel Gear Screw Jacks. To determine the type of screw jack that is best for your application, you need to consider several factors, they are load, self-locking capabilities, travel rate or travel speed, efficiency, accuracy, duty cycle and price, among others.



Worm Gear Screw Jacks includes Machine Screw Jacks and Ball Screw Jacks. The key components of mechanical worm gear screw jacks are: trapezoidal lifting screw and lifting nut(machined screw jacks), or ball screw and ball nut(ball screw jacks), worm screw, worm gear and gear housing. The most common screw jack is the worm gear screw jack, also referred to as machined screw jacks because the acme, or trapezoidal, lead screw is machined. In addition to the low cost and self-locking characteristics, another advantage of machine screw jacks, and all screw jacks, is the mechanical advantage achieved through the internal gear ratio resulting in the ability to lift, lower, push or pull a significant load with a relatively small amount of torque on the drive shaft. Ball screw jacks incorporate a ball screw instead of a machined screw and a ball nut, which activates the screw. The advantage of ball screw jacks and the rolling action of their design is greater efficiency, up to 60%, which is much greater than machined screw jacks. Because of their efficiency ball screw jacks can be used in heavier duty cycle applications. They also provide good positional accuracy in high speed applications. One potential disadvantage is that ball screw jacks are not self-locking and will require a brake or motor with enough holding torque to prevent the ball screw from back-driving. 




Bevel Gear Screw Jacks Advance from having Screw Jack and Bevel Gearbox as a separate unit to a combined Miter bevel gearbox and Screw Jack in a single housing. The Bevel Jack product will save you money by offering less maintenance and fewer components. Available in many configurations, this line offers customers quality, long-duty cycles and configurable solutions for their applications. Available in Bevel Gear Machine Screw Jacks and Bevel Gear Ball Screw Jacks. Although worm gear jacks are sufficient for large loads that are infrequently moved, bevel gear jacks offer more flexibility and programmable options for a wider range of applications. The key components of bevel gear machine screw jacks use the same trapezoidal or acme screws used in machined screw jacks, or ball screws used in ball screw jacks to move the load. However, bevel gear jacks use spiral bevel gears set inside the housing instead of worm gearing. Bevel gears are more efficient than worm gearing, and they have lower ratios that result in higher speeds and travel rates. Typically, bevel gear machine screw jacks maintain self-locking characteristics while providing higher travel speeds, but bevel gear ball screw jacks incorporate a ball screw instead of a machined screw and a ball nut, which activates the screw. The advantage of bevel gear ball screw jacks and the rolling action of their design is greater efficiency, which is much greater than bevel gear machined screw jacks. Because of their efficiency bevel gear ball screw jacks can be used in heavier duty cycle applications. They also provide good positional accuracy in high speed applications. One potential disadvantage is that bevel gear ball screw jacks are not self-locking and will require a brake or motor with enough holding torque to prevent the ball screw from back-driving. 

Another benefit of bevel gear screw jacks is their drive shaft flexibility. They are 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. Flexibility in shaft configuration makes bevel gear jacks ideal for multiple jack configurations and can eliminate the need for stand-alone right angle gearboxes used in many worm gear jack systems.

Additionally, our bevel gear screws can be arranged in three jack configurations: translating, rotating and keyed. This allows the load to be moved in different ways along the lift shaft, offering further options for customers.
