In general, machine screw jacks are the ideal choice for low to moderate duty cycles, lower efficiency, slower speed application. It usually holds the position without a brake, so it’s also quite suitable for manual operation. The prices are cost-effective.
While ball screw jacks are ideal for moderate to high duty cycles, higher efficiency, and faster travel speeds application. It’s not self-locking, requires a brake motor to hold the position. Compared with machine screw jacks, the prices are relatively high.
