Ball Screw

Manufacturer part: 3405N696

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, they 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 direction and 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.Black-oxide alloy steel ball screws and nuts have mild corrosion resistance.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 indicates the diameter the ball screw will be after machining away the threads.
