Keyed Rotary Shafts

Match with a machine key to prevent slipping while transmitting torque to gears and other components. Turned, ground, and polished to tight tolerances, these shafts reduce vibration, evenly distribute loads, and improve accuracy.

Fully Keyed

Mount components anywhere along the length of these shafts. For secure torque transmission, slide a component from either end and lock it into place with an ANSI machine key (sold separately).

Carbon Steel—Strong and easy to machine. These shafts work best in dry environments since moisture will cause steel to rust.

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.

Air-Hardening A2 Tool Steel Rods

Made of A2 steel, they are more wear resistant than O1 rods and discs. They also keep a sharper cutting edge. When heat treated for added wear resistance, they don’t require baths or quenching and can be air-hardened. A2 tool steel is widely used for punches, blades, and hammers. These rods and discs are decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them more machinable and leads to better results from heat treating or finishing. With an oversized diameter, these rods and discs let you finish to your exact requirements.

Ultra-Wear-Resistant 440C Stainless Steel Rods

The high carbon content in this 440C stainless steel helps it withstand abrasion and wear better than any other stainless steel. Like tool steel, it can be heat treated to become extremely hard. It also maintains its corrosion resistance in temperatures up to 800° F. However, it’s more likely to break than bend from impacts. It’s often used to make bearings and valves.

Tight-Tolerance Water-Hardening W1 Tool Steel Rods

Ready for turning in your lathe, these rods are precision ground and held to strict diameter and straightness tolerances. Also known as drill rod. With far less alloy content than other tool steel, W1 is the most machinable we offer. These rods are often used to make hammers, files, and reamers—tools that don't require the dimensional stability of A2 or O1. These rods are also decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them even more machinable and leads to better results from heat treating or finishing. Heat treat the surface for extra wear resistance. Or, quench this steel in water to boost its hardness and strength, giving it a sharper, more durable edge for small tools.
