Keyed Rotary Shafts
Combine these shafts with a machine key (not included) to transmit torque to gears, sprockets, and other power transmission components. All have an ANSI standard keyway (keys not included; see our selection of key stock). Their edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to tight diameter and straightness tolerances.
Steel shafts are generally stronger than aluminum and stainless steel shafts but not as corrosion resistant. 1045 carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use. 4140 alloy steel shafts have a higher yield strength than 1045 carbon steel shafts for supporting heavier loads; however, they are more difficult to machine.
Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 303 and 304 stainless steel shafts have good corrosion resistance. 303 stainless steel shafts are annealed, which makes them softer than 304 stainless steel shafts but more corrosion resistant.

Attach threaded accessories, such as mixer propellers and fan blades, to the end of these shafts.
To Order: Please specify the length of the shaft (in 0.005" or 0.1 mm increments). For the keyed end of the shaft, please specify keyway length (in 0.005" or 0.1 mm increments). For the threaded end of the shaft, please specify thread size, thread length (in 0.005" or 01. mm increments), and step length (in 0.005" or 0.1 mm increments).

Metric 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, these 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 size and travel distance per turn. 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.
For technical drawings and 3-D models, click on a part number.
Root diameter indicates the diameter the ball screw will be after machining away the threads.
