FF Internal Circulation Floating Ball Screw & FFZ with Increased Ball Diameter and Preload

FF
FF3

Note:

1) K is the theoretical calculation value when the preload force F is 0.1Ca and the axial load F is 0.3C;

2) When the axial load F is not equal to 0.3C, K in the formula is the stiffness value in the table

3) The normal working environment temperature range is ±80℃/176°F
