Many of our customers may not be aware that, in addition to our core competency in developing and manufacturing innovative, customized drive solutions, we are also specialized in the production of threaded spindles. As experienced experts in thread rolling, we rely on state-of-the-art machinery and extensive know-how to produce these precise components, which are used both in our own products and in external applications. Our reputation as a reliable, technically skilled partner extends far beyond the borders of Europe and is underscored by our outstanding customer service and our commitment to the highest quality.
Where Robustness Meets Precision Mechanics
High-quality Threaded Spindles for Demanding Industrial Applications
Ketterer Relies on Thread Rolling (Roll Threading)
Our threaded spindles are manufactured using the thread rolling process. In this process, the thread is rolled onto the raw material using two tools. The cold forming ensures a smooth, mirror-like surface and significantly increases the endurance strength. Through this process, our threaded spindles are not only visually appealing but also exhibit lower wear and high efficiency. Additionally, this manufacturing technology is characterized by high material efficiency: Compared to conventionally manufactured threads, we can save up to 20% of raw material, which is a strong argument from both an ecological and economic perspective.
The Advantages of Our Threaded Spindles
The advantages of our threaded spindles speak for themselves: Thread rolling enables the production of threads of outstanding quality. In addition to the benefits of cold forming, these threads also benefit from an optimized thread geometry that further enhances their performance.
- Significantly increased endurance strength
- Higher efficiency levels
- Longer service life
- Low wear
- Low-noise and low-vibration operation
- Higher material and cost efficiency

Higher efficiency thanks to optimized tooth geometry
The thread rolling process ensures that Ketterer spindles have an extremely hard and smooth surface. The optimized tooth geometry, which includes both tooth tip and tooth root roundings, significantly improves the material flow. Thanks to special rollers, the tooth shape and tooth height can be individually adapted to the respective application.
The combination of the smoothly rolled surface and the optimized geometry of the thread enables efficiencies of up to 80 % with very good low-noise and low-vibration running properties.
Quiet and vibration-free operation thanks to rounded teeth
The low-noise and vibration-free running of Ketterer spindles is achieved by the rounded teeth. This special tooth shape minimizes both the contact surface and therefore also the friction between the threaded nut and the spindle. The result is a significant reduction in noise levels and vibrations, which not only makes operation more pleasant, but also extends the service life of the components.
Good mating with plastic nuts due to larger distances between the threads
Größere Abstände zwischen den Gewindegängen der Spindel bieten insbesondere beim Einsatz von Kunststoffmuttern erhebliche Vorteile. Dies ermöglicht einen umfangreicheren Materialansatz in den Gewindegängen der Mutter. Das Risiko von Verschleiß und Beschädigungen wird verringert, was zu einer erhöhten Robustheit und Lebensdauer des Systems führt.
High material and cost efficiency
By specifically optimizing the tooth geometry, spindles up to 3 metres long can be produced with modular threads (worm shafts). Compared to milling, whirling or chasing, this enables worm gear sets to be produced at significantly lower cost: Rolled worm shafts offer material savings of up to 30% and reduce production times by up to 90%. In addition, the rolling process leads to material compaction, which means that cheaper raw material can often be used. The rolled screws are characterized by an extremely hard and smooth surface.
- Material savings approx. 30 %
- Savings in production time < 90 %
- 3 meter worm mill approx. 64 minutes
- 3 meter worm roll approx. 4 minutes
- Due to material compaction often a cheaper raw material is suffi cient
