FAQ
Q Choosing lead?
A
Lead = linear travel per nut revolution. Small (5-10 mm): low speed, high resolution (grinders). Medium (10-20 mm): standard machine tools. Large (25-40 mm): high speed (actuators, robot auxiliary axes).
Q C0/C3/C5 accuracy?
A
C0 ±3.5 μm/300 mm (ultra-precision spindles); C3 ±8 μm (precision machine tools); C5 ±18 μm (standard machine tools); C7 ±50 μm (automation); C10 ±210 μm (handling).
Q Internal vs external recirculation?
A
Internal: balls recirculate within the nut, compact, quiet. External: return tube outside, simple, high load, cheap. Machine-tool precision → internal.
