Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start. Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. To ensure compatibility, select components that have the same thread size and number of thread starts. 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.

Ball Screws—Right-Hand Threaded

Carbon Steel—Carbon steel ball screws and nuts are case hardened, so they resist wear better than standard carbon steel. However, they are less corrosion resistant than black-oxide alloy steel screws and nuts.

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.

Root Diameter—Root diameter indicates the diameter the ball screw will be after machining away the threads.

Self-Stopping Ball Screws and Nuts

Stop Pin Shown Installed

Keep your ball screw spinning without the ball nut damaging your system—a clutch-like collar inside the ball nut prevents it from travelling past the stop pins. Install the included stop pins anywhere along the length of the ball screw by drilling a hole in the valley of the threads (also known as the root) and pressing in the stop pin. When the collar meets the stop pin, the ball nut disengages from the threads and begins to idle. To start the ball nut travelling again, spin the ball screw in the opposite direction. All components are black-oxide steel and have mild corrosion resistance. To ensure compatibility, select components that have the same thread size. 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.

Roller 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. They're most traditionally used to replace hydraulics in linear actuators but can also be used in place of ball and lead screw assemblies because of their high load capacity and precise motion control. In fact, they're almost four times more accurate than our most accurate ball and lead screws. They also last longer than ball screw nuts in systems with lower loads and can handle higher shock loads. However, because they have more contact points, they’re slightly less efficient than ball screws. To ensure compatibility, select components that have the same thread direction and size.

Fast-Travel Corrosion-Resistant Ball Screws and Nuts

Multiple thread channels (also known as thread starts) create faster linear travel than ball screws with a single thread start. Suitable for use in harsh environments, these ball screws and nuts are made of stainless steel. Internal ball bearings provide smooth low-friction travel in applications that require high speeds, accurate positioning, and repeatable movement. To ensure compatibility, select components that have the same thread size. 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.

Ball Screws—Right-Hand Threaded

Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.

Root Diameter—Root diameter indicates the diameter the ball screw will be after machining away the threads.
