Angle Rails for V-Groove Track Rollers
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 Transfer Plates
These plates are designed to rest on a flat surface and are good for rotating and positioning heavy workpieces.
Note: The length and width of the material you're moving should be at least three times the ball spacing.

Ball Screws and Nuts
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.

Self-Stopping Ball Screws and Nuts
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.

Fast-Travel Ball Screws and Nuts
