Ball Screw Drives
Nuts
Kammerer ball screw nuts are designed for precise force transmission, high running smoothness, and long service life. Their application-specific design and high manufacturing quality enable optimal integration into various machine concepts and ensure reliable performance in operation.

The ball screw nut is the heart of ball screw drives. It enables linear movements with high precision, speed, and efficiency. It contains balls that roll in the thread grooves of the spindle, enabling movement with minimal rolling friction, in contrast to the sliding friction of trapezoidal thread nuts.
By rotating the spindle, the nut moves linearly along the spindle. Conversely, by moving the nut, rotation of the spindle can also be generated.
The matching ball screw nuts can be manufactured according to DIN standards, company standards or customer drawings. You decide whether you want to use a single nut or a double nut for the ball screw drive.
For long spindles, we alternatively offer driven nuts that are delivered with a complete bearing package.
Technical
Ball screw drives combine high dynamics with precise and efficient force transmission. With efficiencies of up to 98%, they are ideally suited for fast and highly accurate motion sequences.
Despite medium load capacity, they provide high rigidity and dimensional stability through uniform force distribution.
Questions
- What are the benefits of being able to customize a mold to my specifications?
If the nut can be customized to meet your specific requirements, it can be adapted to the application and the available installation space. This allows the installation configuration, interfaces, fasteners, and additional functions to be precisely tailored, which reduces assembly time and eliminates the need for additional components. In addition, stiffness, preload, seals, and lubrication concepts can be specifically designed to improve the performance, service life, and reliability of the lead screw drive.
- What are the advantages of a driven nut?
A driven nut offers the advantage that the spindle itself remains stationary and only the nut is moved by a motor or drive, thereby reducing the mass that needs to be accelerated. This design results in higher dynamics, faster response times, and lower load capacity. At the same time, it allows for the use of long or heavy spindles, thereby facilitating integration into tight or complex machine-building environments. Furthermore, the direct drive force applied to the nut enables optimization of precision and positioning accuracy.
- When does it make sense to use a driven nut?
A driven nut is a good choice when high dynamics, rapid acceleration, or long spindles are required. Since the spindle is stationary and does not need to rotate, inertia, vibrations, and critical speeds are significantly reduced. This design is particularly advantageous in limited installation spaces, for long travel distances, at high speeds, or when precise positioning is required at high speeds.
