When the highest precision is required in the most confined spaces, HIWIN miniature ballscrews are the ideal solution. They have been specially developed for applications where every millimetre counts and where the most stringent requirements for accuracy, repeatability and reliability must be met.

Thanks to their compact design, with shaft diameters ranging from 4 to 12 mm, these miniature ball screws enable precise linear motion even in the smallest installation spaces. Users do not have to compromise on load capacity, efficiency or service life.
The compact ball screws feature an internal total recirculation system, which ensures smooth and reliable operation. Thanks to the low-friction power transmission, users benefit from high repeatability, low wear and a long service life, even during continuous operation.

Miniature ball screws are used in particular where small sizes and the highest precision are crucial, for example in medical technology, laboratory equipment, optics, metrology, the semiconductor industry and other high-precision automation applications.

Our experienced engineers will assist you in sizing and performing the selection for your application.
