Made through a relatively complex manufacturing process, the CMFZD ball screw is a double flange nut ball screw. It has found a variety of applications due to its large nut installation dimensions. Typically, the ball screw is used for various industrial equipment, precision instruments and precision CNC machine tools.

NOTE
1. KC is the theoretical calculation value when preload Fp is 0.1Ca and axial load F is 0.3Ca.
2. When axial load F is not equal to 0.3Ca.
KC=K(F/0.3Ca)1/3
In formula, K is rigidity value shown in Table.
