Broad, strong Acme threads make these screw jacks better than ball screw jacks for heavy loads, intermittent positioning applications, and where vibration is present.
The mounting plate provides a flat surface for supporting loads.
Add a flat mounting surface to to a screw jack to support loads.
Attach these fittings to the end of a screw jack to create pivoting connections with clevis rod ends and other linkages.
Add a flat mounting surface to a ball screw jack to support loads.
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.
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.
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.
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.
Combine with an externally threaded acme nut to create a custom flange nut.
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.
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.
Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start.
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 ball or lead screw.
A set of ball bearings reduces friction and secures the end of a metric ball or lead screw.
Thread these one-piece collars onto an Acme lead screw.
Mount these two-piece collars anywhere on an Acme lead screw without removing components.
Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.
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.
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.
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.
Secure computer cables and panels.
Use the square head to turn these screws by hand, or use a wrench when you need more torque. Also known as half dog-point set screws, they have a protruding tip that locks within a mating hole or slot to keep parts aligned.
These metric screws have a square head, so you can turn them by hand or use a wrench for more torque. Also known as half dog-point set screws, they have a protruding tip that locks within a mating hole or slot to keep parts aligned.
Turn these metric screws by hand using the hex head, or tighten them with a wrench for extra torque. With an extended tip that locks into a mating hole or slot—sometimes known as a dog point—they are often used to align and secure parts such as gears and pulley wheels.
Use these steel set screws for light duty holding.
These set screws have good chemical resistance.
More corrosion resistant than 18-8 stainless steel set screws, these have excellent resistance to chemicals and salt water.
Alloy steel set screws dig into hard surfaces for a secure hold.
Wrench-adjustable jacks require less clearance to turn than bar-adjustable jacks.
The turning bar gives you leverage to lift heavier loads than wrench-adjustable screw jacks.
Mount these jacks to equipment to raise and level it.
A swivel caster lets you reposition your load.
Fit these compact jacks under low-height loads.
These jacks have a short body to fit in low-clearance spaces.
Pump the handle by hand to raise the jack. Turn the release valve to lower the load.
The ratcheting action makes adjusting these jacks under load easier than screw jack stands.
The screw adjustment allows you to make small changes to the height of your load.
After raising a load, add these steel stands for support.
When working with large or flexible workpieces that could bow under machining pressure, use these screws as easy-to-install support points. Also known as jack screws or jig screws.
Adjust the horizontal screw to hold workpieces of varying sizes in precise positions.
Slide these low-profile supports under a workpiece to provide support and reduce vibration.
From one compact system, transmit linear or rotary motion or both at once (sometimes called spiral motion). Because of these different motions, these ball screw/splines and bearings create efficient, fluid movements in complex automated applications, such as pick-and-place robots.
