SFU1204 Ball Screw Kit

400mm (15.75 in )

Our screw assembly adopts the ball screw production process. The screw and support seat are forged from high-quality carbon steel, and matched with the aluminum alloy bearing block, which has high precision and strong hardness. The ball screw slides smoothly and has low friction resistance. Due to its excellent integrity and high efficiency, ball screw kits are widely used in CNC machine tools, electronic instruments, medical equipment, automation equipment, cutting machine and other fields.
