FFZL type ball screw

Details

FFZL 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 FFZL type ball screw is ±60℃.
