Ball Screw Fast-Travel 3/4-4 Thread Size 2 Thread Starts 2 Feet Long

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.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.
