Stabilize your carriages against pitch, roll, and yaw forces by installing them in pairs.
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.
