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.

Add a flat mounting surface to a ball 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.

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 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.

Install these nuts on a rotary shaft to create a linear positioning system without a lead screw. Instead of threads, a set of angled ball bearings drives the nut along a shaft as it spins.

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.

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.

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.

Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.

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

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.

Precisely drive both linear and rotary motion from one compact system.

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

Precisely position parts in conditions as cold as -90° F.

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