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

Attach these fittings to the end of a 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.

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

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.

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

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.

Keep your ball screw spinning without the ball nut damaging your system. When the ball nut reaches the stop pin at either end of the ball screw, it disengages and begins to idle.

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

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.

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.

Move loads with consistent, repeatable push-pull motion.

Without any hardwiring, these actuators give you control over your push-pull motion using either a hand or foot switch.

Automate precise push and pull movements in clamping, sorting, and ejecting tasks.

With an included controller and an integrated stepper motor, these slides are a complete precision motion control system.

Prevent dust from circulating while precisely positioning parts for drilling, fastening, assembly, and measuring.

Use these slides in a variety of manual-positioning applications for laboratory and production equipment as well as for positioning parts for drilling, fastening, assembly, and measuring.
