A special ball screw bearing support FK serves to fix the screw from displacement along the axis. Bearing supports of screws of the FK series are metal housings with two angular contact bearings inside. Supports of this series are designed for the fixed end of the ball screw screw, i.e. are resistant and perceive both radial and axial loads.
For CNC equipment, ball screw bearings of the following sizes are often used:
FK10, FK12, FK15, FK17, FK20, FK25, FK30, FK35, FK40.
All popular ball screw support sizes can be found in the table below.

В опорах FK стоит пара радиально-упорных подшипников, установленных специальным образом. Именно поэтому опора надежно фиксирует винт ШВП от смещения в осевом и радиальном направлениях.
