Broad, strong Acme threads make these screw jacks better than ball screw jacks for heavy loads, intermittent positioning applications, and where vibration is present.

Add a flat mounting surface to to a screw jack to support loads.

Attach these fittings to the end of a ball screw jack to create pivoting connections with clevis rod ends and other linkages.

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.

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

Also known as trapezoidal-thread lead screws and nuts.

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

Also known as single-start and self-locking lead screws and nuts, these have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest.

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.

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.

Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. Also known as single-start metric ball screws and nuts, these have a single thread that runs the length of the screw.

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

Mount these two-piece collars anywhere on an Acme lead screw without removing components.

A crisscross thread pattern allows you to drive the nut back and forth without changing the lead screw's direction of rotation. When the nut reaches one end of the lead screw, it changes direction and travels back to the other end.
