Rotary Shafts
Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are turned, precision ground, and polished to meet tight diameter and straightness tolerances. This means these shafts evenly distribute loads, reduce vibration, and improve accuracy and stability.
Steel shafts are generally stronger than stainless steel shafts but not as corrosion resistant. Carbon steel shafts balance high strength and good machinability, making them ideal for general purpose use.
Stainless steel shafts are more corrosion resistant than steel shafts but more difficult to machine. 303 stainless steel shafts have good corrosion resistance and are easier to machine than other types of stainless steel.
Shafts with chamfered edges reduce damage to bearings, housings, and other components during installation.

Linear Motion Shafts
Smooth, hard, and wear resistant, these shafts work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. 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. Carbon steel shafts are good for general purpose use. Alloy steel shafts are stronger and more wear resistant than carbon steel.
Stainless steel shafts are more corrosion resistant than steel shafts; however, they’re not as hard as steel shafts and can be more difficult to machine. 420 and 440C stainless steel shafts have good corrosion resistance and are harder than 17-4 PH stainless steel shafts, so they better resist wear.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.

Tapped Linear Motion Shafts
Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed. These shafts work with linear bearings to reduce friction in manual and automated systems because they're smooth, hard, and wear resistant. You'll often see them in packing, machine tool, and material handling operations. All are turned, ground, and polished to tight diameter and straightness tolerances.
The surface is hardened, so they stand up to repeated motion while keeping their center soft enough to absorb stress from shifting loads. Chamfered edges remove sharp corners at the end of these shafts, reducing damage to bearings, housings, and other components during installation.
Alloy steel shafts are stronger and resist wear better than stainless steel.
Surface smoothness—The lower the microinch value, the smoother the finish and the less friction and wear it will cause on the bearing.

Hollow Linear Motion Shafts
Lighter than solid shafts, hollow shafts reduce your total system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center. These shafts are smooth, hard, and wear resistant, so they work with linear bearings to reduce friction in manual and automated systems, such as those found in packing, machine tool, and material handling operations. The exterior of these shafts is turned, ground, and polished to tight diameter and straightness tolerances. The interior is unfinished.
These shafts are hardened on the surface, so they stand up to repeated motion. All have chamfered ends to remove sharp edges and reduce damage to bearings, housings, and other components during installation.
Carbon steel shafts are strong and good for general purpose use.

Support-Rail Shafts
These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating. Shafts have a smooth surface to reduce friction and wear on linear bearings—the lower the microinch value a shaft has, the smoother its finish and the less friction it will create. They are case-hardened to increase hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads. The 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.
Two-piece shafts allow you to replace the shaft when it becomes worn.
Carbon steel shafts are stronger than aluminum shafts but not as corrosion resistant. These shafts balance high strength and good machinability, making them ideal for general purpose use.

Ball Splines and Bearings
Create a compact linear and rotary motion system for applications requiring complex, fast movements, such as robotics. The grooves on the ball splines transmit rotary power as ball bearings move smoothly and precisely along their length, even at high speeds.
Ball splines are alloy steel for high strength and wear resistance. They're hardened on the outside for additional wear resistance while the center is soft enough to absorb stress from shifting loads.
Bearings have a retaining ring groove, so they can be positioned in your system with a retaining ring (not included). Bearings with a keyway include a machine key for attaching your load. Flanged bearings have a surface with mounting holes for attaching your load.

- Yield Strength: 73,000 psi
- Hardness: Brinell 150 (Medium)
- Temper: T6
- Fabrication: Cold Worked
- Specifications Met: ASTM B211
Ready for turning in a lathe, these rods are precision ground and held to a strict straightness tolerance. Originally developed for aircraft frames, uses for 7075 aluminum now include keys, gears, and other high-stress parts. It is often used as a replacement for 2024 aluminum because it’s stronger and provides similar performance in all other aspects.

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.
Carbon steel ball screws and nuts are case hardened, so they resist wear better than standard carbon steel. However, they are less corrosion resistant than black-oxide alloy steel screws and nuts.
Travel distance per turn, also known as screw lead, is the distance a ball nut moves with one revolution of the ball screw.
