Lead screws are less expensive and easier to manufacture. It is a lot more cost-efficient than ball screws in intermittent, reduced speed, and light to medium excess weight applications.
A hydrostatic leadscrew overcomes lots of the drawbacks of a traditional leadscrew, obtaining higher positional precision, extremely small friction, and very small use, but requires a ongoing supply of substantial-pressure fluid and significant precision manufacture, leading to a appreciably higher Charge than most other linear motion linkages.
