Ball Screw with Single Nut Flange End Face SFD

ISUTAMI SFD ball screw with single end face flange nut assembly is an outer circulation nut ball screw combination, the ends of the nut are reinforced plastic seal. It has obvious advantages in high rigidity, low noise and temperature rise control, and is suitable for high lead ball screws. The average accurate pitch diameter of the ball on the thread in the assembly allows the ball screw to obtain a consistent preload pressure and reduce the noise value. The high-rigidity, wear-resistant reinforced plastic backflow system keeps the ball running low and smooth.
