Selection Criteria
Here, you'll learn how to quickly and easily select the right drive product and calculate important parameters such as duty cycle, deflection, speed, and more. You'll also discover how to avoid incorrect purchases and why electromechanics is often the better choice compared to hydraulics or pneumatics.
FAQs about Selection Criteria
Yes, for Screw Jacks with ball or roller screw mechanisms, a lifespan can be calculated. However, for trapezoidal screw mechanisms, lifespan calculation is not possible. More information on the calculations can be found here.
There is no calculation basis for this. The buckling length has been determined through tests. You can find a corresponding diagram for horizontal applications here: General Catalog 2023 (grob-antriebstechnik.de). For vertical applications, please contact us.
- The load must be guided
- The Linear Chain size must be chosen correctly
- It should be driven over a ramp
You have several options for achieving this:
- Modifying the gear ratio
- Modifying the spindle pitch
- Adjusting the motor speed
All of these measures are available in many standard configurations from us
The determining factor for motor size is power, which results from the product of speed and torque. For more information on this topic, please refer to our Learning Center.
Yes, threaded spindles can also be equipped in stainless steel.
