Ball Screw Support Unit are designed to absorb the parallel error in between screw shaft and guide.
We provide BF-type and BK-type support units, the most common types of ball screw support bearings used in Industry. The structure of ball screw support bearing is such that as the rotational shaft or ball screw rotates and the bearings need to be in face-to-face contact, high rigidity angular contact ball bearings are installed in the fixed portion of the support unit. Furthermore, it allows for highly precise rotational or linear motion during assembly thanks to the precise control of preload.
Features:
- Uses the Optimal Bearing
- Support Unit Shapes
- Compact and Easy Installation
BF type
BF type ball screw support units have a fixed end support structure, which is suitable for vertical applications. The fixed end support prevents axial movement and ensures smooth operation. The BF type support unit is often used in machine tools, automation equipment, and robotics. The BF type is suitable for vertical applications with high rigidity and axial load capacity. The advantages of the BF type support unit include high rigidity, low noise, and excellent axial load capacity.
BK Type
BK type ball screw support units are designed with both fixed and floating end supports, which are suitable for horizontal applications. The floating end support allows for axial movement and compensates for thermal expansion. The BK type support unit is often used in CNC machines, milling machines, and lathes. The BK type is suitable for horizontal applications with high precision and low backlash. The advantages of the BK type support unit include high precision, smooth operation, and low backlash
FF type
FF type ball screw support units have a flange-mounted design with fixed end support and are suitable for both horizontal and vertical applications. The flange-mounted design allows for easy installation and reduces assembly time. The FF type support unit is often used in medical equipment, semiconductor equipment, and packaging machines. The FF type is suitable for compact designs with high accuracy. The advantages of the FF type support unit include high accuracy, high rigidity, and compact design.
Fk type
FK type ball screw support units have a compact design with both fixed and floating end supports and are suitable for high-speed applications. The compact design reduces the overall weight and saves space. The FK type support unit is often used in printing machines, semiconductor equipment, and high-speed pick-and-place machines. The FK type is suitable for high-speed applications with low noise and vibration. The advantages of the FK type support unit include high speed, low noise, and low vibration
