About Shafts

Keyed Rotary Shafts

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

Partially Keyed Rotary Shafts

These shafts have keyways only on the ends, leaving a plain shaft in the center. Use the keyways with machine keys to transmit torque to gears, sprockets, and other keyed components. Use the middle of the shaft with bearings and other round-bore components.

Keyed Rotary Shafts with Material Certification

In addition to diameter tolerances that are twice as tight as standard keyed shafts, these shafts include a traceable lot number and test report. Use them with machine keys to transmit torque to gears, sprockets, and other power transmission components.

Rotary Shafts

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

Ultra-Straight Tight-Tolerance Rotary Shafts

Eight times straighter than standard rotary shafts, these tight-tolerance shafts minimize vibrations and reduce wear to bearings and other components. They also have diameter tolerances that are twice as tight as standard rotary 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 D-Profile Rotary Shafts

Connect these internally threaded shafts directly to threaded components, or use a fastener to secure. They have a flat surface area that 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.

Splined Rotary Shafts

With a splined profile on one end, these shafts transmit high rotational loads—good for hydraulic systems, machine tools, and other high-torque applications. Compared to keyed shafts, they last longer, handle higher torque, and do not require as tight of a fit.

Threaded Rotary Shafts

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

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.

Linear Motion Shafts

Combine these general purpose shafts with a linear bearing and shaft support to create a basic linear motion system.

Tapped Linear Motion Shafts

Internal threads allow you to mount these shafts onto threaded studs and fasteners, no shaft supports needed.

Threaded Linear Motion Shafts

Mount these externally threaded shafts into tapped holes rather than using a shaft support, or attach a hex nut, shaft collar, or other threaded accessory.

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.

Hollow Linear Motion Shafts with Material Certification

Keep a material certificate on hand for compliance and quality assurance needs. Certificates include a traceable lot number and material test report. These hollow shafts reduce system weight and allow you to run various media such as electrical wiring, compressed air tubing, coolants, or lubricants through the center.

Linear Motion Shafts with Machinable Ends

With 2" of each end softened, it's easier to machine a custom end for mounting. The rest of the shaft is case-hardened, which increases hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads.

Step-Down Linear Motion Shafts

A shoulder near the end of the shaft allows for easy positioning of housings, shaft supports, and collars.

Linear Motion Shafts with Retaining Ring Grooves

Clip retaining rings into the grooves to separate and position collars, supports, and housings.

Shafts for Support Rails

Replace worn shafts in two-piece support-rail shaft systems, or mate with a support rail to create your own. The tapped mounting holes match those on our Support Rails.

Support-Rail Shafts

These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating.

Metal

Low-Carbon Steel Rods and Discs

Also known as mild steel, low-carbon steel is easy to machine, form, and weld. It's widely fabricated into parts that don’t require high strength.

Polished Multipurpose 304 Stainless Steel

Polished to either a brushed or mirror-like finish, this material is often used to fabricate decorative enclosures and industrial workstations.

Polished Multipurpose 6061 Aluminum Rods

Choose between rods that are polished to a brushed finish or a mirror-like finish.

Polished Multipurpose 6061 Aluminum Round Tubes

Polished on the outside to a #8 reflective, mirror-like finish, these tubes have no visible grain lines.

Ultra-Formable 260 Brass Wire

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. 260 brass is sometimes called cartridge brass. This wire has a soft temper and stays in place when bent.

Ultra-Strength Easy-to-Form 510 Bronze Wire

Because 510 bronze is very strong and formable, it is the best choice for applications involving repetitive motion, such as springs and bellows.

Mirror-Like Multipurpose 110 Copper Wire

This wire is polished to a mirror-like finish.

High-Temperature Nickel-Clad Copper

This copper wire is clad in nickel to provide excellent corrosion resistance at temperatures up to 1200° F while maintaining high electrical conductivity.
