Ball screw

Ball screws are essential components in many mechanical systems, providing efficient and precise linear motion. At Tuli, we offer a comprehensive selection of ball screws to meet the diverse needs of various industries and applications. Explore our range and find the perfect ball screw to enhance the performance of your machinery.

Basic Functionality of Ball Screws

Ball screws are mechanical devices used to convert rotational motion into linear motion with minimal friction. They consist of a threaded shaft (screw) with recirculating ball bearings (nuts) that move along the threads, allowing for smooth and precise movement. Ball screws are widely used in applications requiring high precision and efficiency, such as CNC machines, industrial robots, and aerospace equipment.

Types and Shapes of Ball Screws

Ball screw nuts are available in standard sizes from 8x1 mm up to 100x20 mm. Ball nuts are available in cylindrical or flange shape. Beside standard type of ball nut, we offer also miniature, high speed, high load, and dustproof types. Ball screws are available in three lead accuracy classes C3 (0,008/300 mm), C5 (0,023/300 mm) and C7 (0,050/300 mm). Ball screws can be cut to length and end machining of the screw can be done to fit ball screw end support.

About the author

Jure Pleško is co-owner of Tuli, a family business that helps innovative mechanical engineers by supplying them with machine elements to assemble machines and devices. As part of a family tradition, he grew up with machine elements from an early age and also completed his studies in mechanical engineering, earning a Master's degree in Mechanical Engineering. As a 2-year-old child he was also the inspiration for the company name, because at that time he was shouting a lot and hence the name Tuli, which in translation means screaming. Jure is an innovative mechanical engineer himself, which he proved during his student years with the construction of an electric vehicle, which was also awarded by the Slovenian Fund for Human Resources Development and Scholarships.
