High-quality Threaded Spindles for Demanding Industrial Applications

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 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.

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
• Reduced wear
• Higher effectiveness
• Quiet and low-vibration operation

Thanks to the thread rolling process, Ketterer spindles have a very smooth surface and an optimized tooth geometry depending on the application. By using customized rolling dies, it is possible to adjust the contour of the tooth to match the counterpart.

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 characteristics.

Another application is the Ketterer module spindles. Through clever optimization of the geometry, it is possible to produce a module worm up to 3 meters long. In further connected manufacturing processes, cost-effective worm gear sets can thus be produced. The rolled worms feature an extremely hard and smooth surface.

Greater spacing between the thread turns of the spindle offers significant advantages, especially when using plastic nuts. This allows for a more substantial material engagement in the thread turns of the nut. The risk of wear and damage is reduced, leading to increased robustness and longevity of the system.
