About Carbon Steel, Alloy Steel, Spring Steel, and Cast Iron

Thick-Wall Steel Unthreaded Pipe

Typically used with thick-wall and high-pressure iron and steel unthreaded pipe fittings. Also known as Schedule 80.

Alloy Steel

Easy-to-Weld 4130 Alloy Steel Round Tubes

4130 alloy steel has a low carbon content that provides good weldability. It's often used for gears, fasteners, and structural applications.

Easy-to-Weld 4130 Alloy Steel Rectangular Tubes

4130 alloy steel has a low carbon content that provides good weldability. It's often used for structural applications.

Multipurpose 4140 Alloy Steel Tubes

Also known as chrome-moly steel, this versatile 4140 alloy steel is used for a wide range of parts, such as axles, shafts, collets, and die holders. It resists fracturing from repeated stress.

Rotary Shafts

Use these general purpose shafts with bearings, sprockets, and gears to transmit rotary motion.

Keyed Rotary Shafts

Combine with a machine key to transmit torque to gears, sprockets, and other power transmission components.

Threaded Rotary Shafts

Attach threaded accessories, such as mixer propellers and fan blades, to the end of these shafts.

D-Profile Rotary Shafts

A flat surface area allows set screws to dig into the shaft for securely mounting gears, sprockets, and bearings.

Tapped Rotary Shafts

Connect these internally threaded shafts directly to threaded components, or use a fastener to secure.

Step-Down Rotary Shafts

A shoulder near the end of the shaft provides a stop for gears, sprockets, and bearings.

Rotary Shafts with Retaining Ring Grooves

Clip retaining rings into the grooves to separate and position gears, sprockets, and bearings.
