Use these rails with any track rollers that have a 90° V-groove. The bottom can be drilled for mounting.
420 stainless steel rails are more corrosion resistant than steel rails. Use them in areas where frequent washdowns with harsh cleaners take place.
Rails with a Rockwell hardness rating offer improved wear resistance over unhardened rails. The higher the hardness rating, the harder the metal.

Ball Screws and Nuts
![](/prerenderstable/mvPRE/contents/gfx/imagecache/596/5966k241p2-d03c-digital@halfx_636982087088463088.png?ver=imagenotfound)
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.

Fast-Travel Ball Screws and Nuts

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.
