Selection & Decision Support
Anyone looking for the right drive solution is quickly faced with a wide range of options - from screw jacks to electric cylinders. But which solution fits your specific application? Which technical requirements are critical?
Here you will learn how to properly select specific linear actuators and avoid costly purchasing mistakes.
How to solve these problems – with practical, application-oriented articles
I’ve found several drives, but which one truly fits my application?
I don’t want to make an expensive mistake
The product data is available, but how do I select the right option?
I’m not sure whether I know all the important selection criteria
Identifying the right solution
Anyone looking for the appropriate drive technology for an application often faces a confusing variety of options: Should it be a screw jack or an electric cylinder? Is a standard drive sufficient, or is a specialized solution required? And which criteria are truly decisive for selection? Especially in the early project stages, the necessary knowledge to make the right decision is often lacking.
Guidance instead of guesswork
The goal of this section is to provide clear guidance. You’ll learn how to proceed in a structured, practical way, what to focus on when selecting a drive, and how to avoid common pitfalls — even without in-depth prior knowledge of drive technology.
Let's dive in:
FAQs
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.
