FF type ball screw

Details

FF type ball screw

Notes:

1. Kc is 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 FF type ball screw is ±60℃.
