FAQ - Microball answers all your questions:
Where are ball screw drives used?
A ball screw drive converts rotary motion into precise linear motion.
Small balls circulate between the screw shaft and the nut, significantly
reducing friction. Thanks to this ball circulation technique, the
movement is particularly smooth and efficient. The balls carry the load
and roll in specially shaped raceways, which not only increases accuracy but also minimizes wear. This combination ensures long service life and precise positioning in demanding applications.
Where are ball screw drives used?
Ball screw drives are used in a variety of technical fields where precise
linear movements are required. Typical applications include machine
tools, CNC machines, robotics, medical technology, and automation
technology. They ensure efficient and accurate conversion of
rotary into linear motion, enabling high positioning accuracy and
repeatability. Ball screw drives are particularly valued for their
durability, high efficiency, and ability to move heavy loads precisely.
What are ball screws?
Ball screws are mechanical guide elements that convert rotary motion into precise linear motion. They consist of a threaded spindle and a matching nut, between which numerous small balls act as rolling elements. These balls roll between the thread grooves, significantly reducing friction and wear compared to conventional screw drives. Thanks to their high accuracy, efficiency, and smooth operation, ball screws are widely used in mechanical engineering, automation, and precision technology.
Balls for Ball Screws
Low-Friction Linear Motion with Maximum Efficiency
Balls play a central role in ball screws, where they convert rotational movements into precise linear motion. A ball screw, also known as a recirculating ball screw, is an axial screw drive characterized by the positive engagement of the raceway grooves of the screw and the nut. In the spiral guide tube, the balls roll as rolling elements, ensuring low-friction and precise movement.
Thanks to their high accuracy and efficiency, ball screws are widely used in industrial and precision machines and are considered the preferred solution for linear drives with the highest demands on precision and
load capacity.
microball GmbH offers balls in various materials and sizes, optimally tailored to the specific application.
Chrome Steel Balls for Ball Screws
Chrome steel balls are characterized by their exceptional hardness and wear resistance. They ensure precise and reliable conversion of rotational motion into linear movement. Thanks to their robust material properties, they are particularly resistant to mechanical stress and are ideal for applications with high demands and long service life.
Stainless Steel Balls for Ball Screws
Stainless steel balls offer an excellent combination of precision
and corrosion resistance. They enable smooth and quiet
movement in ball screws, even under humid or aggressive
environmental conditions. Due to their resistance to rust,
they are particularly well suited for applications where high
durability against environmental influences is required
alongside mechanical performance.
Ceramic Balls for Ball Screws
Ceramic balls are distinguished by their low weight and
exceptional hardness, which guarantees high wear resistance.
These properties ensure particularly precise movements with reduced friction and increased temperature resistance.
This makes them ideal for demanding applications where
smooth operation, durability, and chemical resistance are crucial.
