AM Nut Design
Our ball recirculation system has been proven over many years and continuously developed to perfection. Under specific application conditions, the following characteristic values can be achieved:
nperm × d0 = 200,000 Permissible Speed Factor
150 m/min Maximum Speed
20 m/sec² Maximum Acceleration
Ball Recirculation Design
Optimized geometry and manufacturing precision ensure smooth ball transfer within the nut wall, providing the following advantages:
- Uniform and Quiet Operation - Suitable for all speed ranges
- High Axial Rigidity - Combined with minimum friction
- Optimal Concentricity - Nut internal thread ground over full length, no inactive threads
- Complete Protection - Smooth enclosed profile protects ball return track from contamination and damage
Preload System
AM Fixed Preload
The proven AM fixed preload uses keyway-type fitting. We set the preload value, and it remains constant throughout the entire service life.
Wiper Seals
Internal Brush-Type Wiper Seals
- Circumferential Direction - Elastically adaptable to thread profile
- Axial Direction - Reinforced by backing plate, prevents contamination of lubricant film
- Low Friction - Prevents heat generation
- Improved Wiping Effect - Ground thread profile on base enhances performance
For special applications (such as machining of castings, aluminum, magnesium, etc.), we provide professional advice and special designs.
