Ball Screw

The FFZD ball screw is a ball screw equipped with preloaded double flange nut. It is available in nominal diameters from 12-120mm with leads down to 1mm. With small nut installation dimensions, the ball screw is suitable for use in situations requiring small, medium leads, and low, medium speeds. The FFZD ball screw provides high positioning accuracy for equipment, precision instruments, precision CNC machine tools, and more.

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.
3. The normal working environment temperature for FFZD type ball screw is ±60℃.
