AM Ball Screws - Installation & Protection
Installation Notes & Protective Devices
Installation Notes
To ensure proper function, we recommend that the perpendicularity of your flange locating surface to the screw axis be maintained within the range shown in the illustration, i.e., alignment of bearings and guide rails must also be observed.
Important Warnings
- The nut must be prevented from being subjected to any static or dynamic radial forces
- Disassembly of the nut is prohibited
In the case of vertical ball screw applications, the machine manufacturer must check whether a safety stop device needs to be provided.

Protective Devices
Contaminants and Foreign Objects
The working space of the ball screw should be protected by appropriate covers to prevent chips, abrasive particles, or other foreign objects from entering.
Even soft particle deposits such as fibers, wood shavings, and other substances that obstruct the lubricating film must be avoided.
In principle, we recommend the use of wipers.
Overload Protection
Overload from Collision or Impact
Overload clutches and predetermined breaking points are recommended because impact loads exceeding the static load rating may occur during collisions. This protection is especially important when the screw has a high moment of inertia.
If limit switches are overrun, buffer devices can prevent damage.
Storage Notes
Storage Requirements
Never place ball screws on the nut; store them on V-blocks.
