Ball Screw
The FFZL ball screw is a double nut ball screw made through a relatively simple manufacturing process. Because of its small nut installation dimensions, the ball screw is designed for use in situations requiring small, medium leads, and low, medium speeds. Applications include various industrial equipment, precision instruments, precision CNC machine tools, and more.

NOTE
1. KC is the theoretical calculation value when preload Fµ is 0.1Ca and axial load F is 0.3Ca
2. When axial load F is not equal to 0.3Ca.
KC= K (F/0.3 Ca)1/3
In formula, K is rigidity value shown in Table.
3. The normal working environment temperature for FFZL type ball screw is ±60℃.
