Ball screw actuator
Our focus is always on optimal precision and cost-effectiveness. To ensure these characteristics over the long term, the ball tracks, bearing seats and contact surfaces for the ball screws are precision ground. This enables optimum force transmission with a high degree of positioning accuracy and repeat accuracy. The path distance is measured via the spindle.
Areas of application for ground ball screws
- Machine tools
- Process machines
- General mechanical engineering
- Robotics and automation
- Drive technology
- Plastic injection molding machines
- Measuring and testing technology
For demanding applications, the new Schneeberger ball screws (SBS) stand out for their precision and efficiency, primarily attributed to the ground and hardened ball contact surfaces.
They are adept for use across a wide range of speeds, from high to low, and are perfect for oscillating short stroke movements. This versatility makes them especially appealing for use in machine tools, as well as in measuring and testing technology.
A.MANNESMANN Ball Screws
Ball screws from AM are manufactured in the accuracy classes IT 1, IT 3, or IT 5. They are equally suitable for both horizontal and vertical use. The preloaded ball screws can typically withstand axial force loads of up to 30% of the dynamic load rating. At a standard travel speed and acceleration, they often achieve an operational lifespan of significantly more than 20,000 hours.
Areas of Application
The use ultimately determines the structural design and manufacturing method of a ball screw. Ball screws find application not only in "normal" domains but also in specialized areas such as high-speed, heavy-load, short-stroke and oscillation (micro-move), and smooth operation ranges (e.g., grinding drives). Additionally, they are capable of operating safely under unique environmental conditions like underwater or at high temperatures.
The technological requirements and expectations vary significantly across different application areas, being highly specific and sometimes even contradictory. For instance, a ball screw designed to handle very high loads will not be suited for achieving very high travel speeds. Conversely, a ball screw that is highly dynamic will endure comparatively lower forces.
When a large mass needs to be moved in small increments, high dynamics are not necessary; instead, low breakaway torque and minimal friction are prioritized.
Consequently, it necessitates specialized structural designs tailored as closely as possible to the specific application profile.

- Ground Bearing Seats: Perfect bearing fit ensures stability and efficiency.
- Non-Interrupted Mounting Shoulder: Enables optimal connection of fixed bearings for maximum stability.
- Ground Bearing Seat on Nut: Provides optimal positional tolerance and internal ball recirculation, resulting in low noise and protected ball return.
- Combinable Wiper Systems: Offers optimal protection for the nut's interior, supporting a long life cycle while reducing lubricant loss.
What are the available wiper systems and their features?
SCHNEEBERGER offers three types of wiper systems for their ball screws: Brush wiper (BW), Finger wiper (FW), and Double wiper (DW), which is a combination of brush wiper and finger wiper. These wiper systems are designed to provide optimal protection for the ball screw mechanism.
The Brush wiper (BW) is suitable for normal loads and comes with a length dimension of l2 (standard), offering a very compact design integrated into the nut body. The Finger wiper (FW) is designed for heavy stresses, with a length measurement of l2 + 20 mm and a sealing lip adapted to the profile geometry for optimal sealing efficiency. The Double wiper (DW) combines the features of both brush and finger wipers, offering versatility and protection. When ordering Schneeberger ball screws, customers can specify their preferred wiper type along with other product specifications like thread length, spindle type, and flange shape to ensure the desired performance and functionality.
What applications can they used for?
Our ball screws are essential in demanding applications like machine tools, measuring, and testing machines, ensuring precise positioning and repeat accuracy. They also find use in process machines, general mechanical engineering, robotics, automation, drive technology, and plastic injection molding machines for their smooth operation and constant torque.
How do I maintain and extend the life of them?
Proper maintenance is crucial to extending the life of a ball screw. This includes regular lubrication to minimize friction and wear, cleaning to remove debris, and inspection for any signs of wear or damage. SCHNEEBERGER provides detailed maintenance guidelines and recommendations for their ball screws to ensure optimal performance and longevity.
