Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start.

Also known as single-start ball screws and nuts, these have a single thread that runs the length of the screw. They operate with more torque than fast-travel ball screws and nuts.

A set of ball bearings reduces friction and secures the end of a ball or lead screw.

Precision ground to create more points of contact, these roller screws and nuts are highly accurate and handle much higher loads than ball screws and nuts of the same size.

Low-friction ball bearings allow these screw jacks to use half the power required by an Acme screw jack to lift the same load. Typically used as actuators, they run at higher speeds than Acme screw jacks.
