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.
Also known as trapezoidal-thread lead screws and nuts.
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 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 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.
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.
Worm gears use screw threads to reduce shaft speed by ratios of 10:1 and greater while transmitting motion at a right angle.
These plastic gears are lighter and quieter than metal gears—pair them with metal worms for lubrication-free operation. Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle.
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.
