About Shafts

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.
Shafts with chamfered edges reduce damage to bearings, housings, and other components during installation.

Low-Carbon Steel Rods and Discs
- Yield Strength: See table
- Hardness: See table
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: See table
- Fabrication: See table
- Specifications Met: See table
Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into low-strength fasteners, pins, and axles. You can surface harden this material for added wear resistance. All have been manufactured to meet ASTM standards for quality and performance.
Cold-worked rods and discs have a finished look and quality. The cold-working process gives the steel consistent strength, hardness, and dimensions throughout.

Tight-Tolerance Multipurpose 4140 Alloy Steel Rods
- Yield Strength: 60,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C60
- Fabrication: Cold Drawn
- Specifications Met: ASTM A108
Ready for turning in your lathe, these rods are precision ground and held to a strict straightness tolerance. Also known as chrome-moly steel, this versatile alloy steel is used for a wide range of parts, such as gears, axles, shafts, collets, and die holders. It resists fracturing from repeated stress. For added wear resistance, you can surface harden these rods with heat treating. They are manufactured to ASTM A108 standards for performance and quality.
Note: Rods may be made from either 4140 or 4142 alloy steel. They are interchangeable in most applications.

Tight-Tolerance Multipurpose Oil-Hardening O1 Tool Steel Rods
- Yield Strength: 50,000 psi
- Hardness: Rockwell B90 (Medium)
- Heat Treatable: Yes
- Maximum Hardness After Heat Treatment: Rockwell C65
- Fabrication: Hot Rolled
- Specifications Met: ASTM A681
Ready for turning in a lathe, these rods are precision ground to a tight diameter tolerance. They’re also known as drill rod. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion. It can also be surface hardened with heat treating for added wear resistance. These rods have been manufactured to meet ASTM A681 standards for performance and quality.

Tight-Tolerance Multipurpose Air-Hardening A2 Tool Steel Rods
Precision ground and held to a strict straightness tolerance, these rods are ready for turning in your lathe. Also known as drill rod, this A2 tool steel is more wear resistant than O1 and keeps a sharper cutting edge. It’s air-hardening, so it doesn’t require baths or quenching after heat treatment. This tool steel is often used for punches, blades, and hammers. These rods have been manufactured to ASTM A681 standards for performance and quality.
