This ballscrew support unit is comprised of a main body, bearing and spacers. The Unit is used on the floating supported end of the ballscrew shaft making it possible to place it in the correct position. The compact size makes it easy to mount and can be used in narrow spaces. Additionally, an adequate amount of grease has already been sealed within the bearing to adjust it to the optimal state for use so that it can be installed immediately on the machine to reduce assembly operation time and improve assembly accuracy and consistency.
