Ball Screw ( Vít me bi )

The nut flange shape, mounting holes and rated load are compliant with DIN69051

A Ball Screw that achieves low noise, small torque fluctuations and long-term maintenance-free operation by using a ball cage.

A Ball Screw using a screw shaft ground to high accuracy.


A Stroke/Rotary unit that has Ball Screw grooves and a Ball Spline groove crossing one another on a single shaft. The nuts of the Ball Screw and the Ball Spline have dedicated support bearings directly embedded on the circumference of the nuts.

A Ball Screw using a screw shaft roll-formed to high accuracy.

This type of Ball Screw is mass manufactured by cutting the standardized screw shafts of Precision Ball Screws to regular lengths. Additional machining of the shaft ends can easily be performed.

The use of a guide plate system provides a compact design with a round outer diameter for the nut. The screw shaft is roll-molded with a high degree of precision to ensure smooth operation.


The Support Unit comes in six types: models EK, FK, EF, and FF, which are standardized for standard Ball Screw assembly provided with finished shaft ends, and models BK and BF, which are standardized for ball screws in general. The Support Unit on the fixed side contains a JIS Class 5-compliant angular bearing provided with an adjusted preload.

The nut bracket is standardized for standard Ball Screw assembly provided with finished shaft ends. This model is designed to be secured directly on the table using bolts. Since the height is low, it can be mounted on the table only using bolts.

The Lock Nut for Ball Screws is capable of easily fastening the screw shaft and the bearing with high accuracy. A loosening prevention mechanism comprising a hexagonal socket-head setscrew and a set piece prevents the Lock Nut from loosening and ensures firm fastening.
