Selecting Compatible Lead Screws and Nuts

Metric Acme 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. To ensure compatibility, please select components that have the same thread direction, size, and pitch. Class 7E and 7H components are compatible.
Black-oxide carbon steel components have mild corrosion resistance. 932 bearing bronze components are more wear resistant than brass components. They have good machinability and fair corrosion resistance.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Metric Precision Acme Lead Screws and Nuts
Pair with a motor in automated motion and positioning applications. A tight thread fit allows these lead screws and nuts to make accurate, repeatable starts and stops. Also known as single-start and self-locking lead screws and nuts, they 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. To ensure compatibility, select components that have the same thread size.
Lead screws are 1018 carbon steel for good machinability.
932 bearing bronze nuts have good machinability and wear resistance. Manganese bronze nuts have good strength and wear resistance.
Travel distance per turn, also known as screw lead, is the distance a nut moves with one revolution of the lead screw.

Metric 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 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. To ensure compatibility, select components that have the same thread size and pitch. Ball nuts are furnished with a tube to keep ball bearings in place. Do not remove the tube until you are ready to install the nuts onto the screws.
Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.

Metric Fast-Travel Ball Screws and Nuts
With multiple thread starts, these metric ball screws create linear travel that’s approximately three times faster than ball screws with a single thread start. They’re ideal for applications with an actuator. The ball nuts have internal ball bearings to produce smooth, low-friction travel for applications that require high speed, accurate positioning, and repeatable movement. They come with a tube to keep the ball bearings in place. Do not remove the tube until you’re ready to install the nuts onto the screws. All of these ball nuts have an end cap on each end to stabilize fast-rotating motion. End caps also dampen the noise from the ball bearings and make the ball nuts more compact. Seals on the ball nuts keep out dust.
To ensure compatibility, select components that have the same thread size and pitch.
Ball nuts with four mounting holes have a lower profile than ball nuts with six mounting holes, so they’re better when assembly height clearance is tight.
Ball nuts with six mounting holes have a support bearing for greater axial rigidity than ball nuts with four mounting holes. They’re responsive to motor and actuator movements.
Root diameter indicates the diameter the ball screw will be after machining away the threads.
Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.
