Steel Shafts | McMaster-Carr

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.

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.

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.

Threaded Rotary Shafts

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

Thread-Mount Idler Rotary Shafts

Thread these shafts into a tapped hole to support idler sprockets and pulleys in tensioning applications. They have a retaining-ring groove, retaining ring, and spacers to position your component and hold it in place.

Flange-Mount Idler Rotary Shafts

Mount the flange to a machine or wall to support idler sprockets and pulleys in tensioning applications. They include washers and a nut to position your component and hold it in place.

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.

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.

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.

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 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.

Linear Motion Shafts with Retaining Ring Grooves

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

Easy-Access Flange-Mounted Shaft Supports

A removable collar allows access to the shaft without unbolting the flange. For use with light to medium loads where shaft alignment is not critical, these carbon steel supports allow you to hold linear shafts perpendicular to the mounting surface. Secure the shaft by tightening the clamping screw.

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.

Low-Profile Support Rails

At approximately one-third the height of standard versions, these rails provide linear shaft support in applications with low vertical clearance. They provide stability over the entire length of shaft, allow virtually unlimited travel lengths, and eliminate bending under moderate to heavy loads.

Splined Shafts for Rotary and Linear Motion

Grooves on the surface of these shafts transmit rotary power while allowing bearings to move freely along the length of the shaft.

Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects.

Metric Acme Lead Screws and Nuts

These metric lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. They're commonly found in hand-powered clamps, vises, grates, doors, and work tables.

End Supports for Lead Screws and Ball Screws

A set of ball bearings reduces friction and secures the end of a ball or lead screw.

Metric End Supports for Lead Screws and Ball Screws

A set of ball bearings reduces friction and secures the end of a metric ball or lead screw.

Self-Reversing Lead Screws and Nuts

A crisscross thread pattern allows you to drive the nut back and forth without changing the lead screw's direction of rotation. When the nut reaches one end of the lead screw, it changes direction and travels back to the other end.

Clamping Acme Lead Screw Collars

Thread these one-piece collars onto an Acme lead screw.

Two-Piece Clamping Acme Lead Screw Collars

Mount these two-piece collars anywhere on an Acme lead screw without removing components.

Metric Clamping Acme Lead Screw Collars

Install these threaded collars on a metric lead screw to separate and position components, or use them as an end stop to limit travel.

Gear Rod Stock

Machine your own gears to fit the exact face width and shaft diameter required.

Recycled Plastic and Metal Composite Sheets

Made of recycled steel mill scale and reground plastic, these sheets are a sustainable, low-cost alternative to standard composites often used as counterweights, such as lead and steel.

Flexible Shafts

Made of steel, these shafts are stronger than stainless steel flexible shafts.

Heavy Duty Flexible Shafts

With a strong steel core, a protective plastic case, and bearings, these shafts handle the demands of high-torque applications.

Building and Machinery Hardware

Lever Handles

An easy-to-grip ball knob makes these handles a good replacement for gear levers. Use them to operate machinery.

Ball-Lever Shafts

Attach a ball knob to one of these shafts to create custom handles for operating machinery.

Rebar

Protect concrete from cracking due to tensile force, such as expansion caused by temperature changes.

Driver Shafts

Ball-End Driver Shafts

Create your own tool by attaching these shafts to a handle, or use with socket wrenches and power tools. They have a ball end that allows angled entry to make good contact with the recess when a standard-tip shaft can’t.

Ball-End Driver Shaft Sets

These assorted shafts attach to a handle or can be used with socket wrenches and power tools. They have a ball end that allows angled entry to make good contact with the recess when a standard-tip shaft can’t.

Clamping and Workholding

Setup Studs

Combine these setup studs with T-slot nuts, flanged nuts, setup clamps, or setup blocks to clamp and hold workpieces, vises, and other objects onto your fixturing table. Also known as double-ended studs, they have threads on both ends.

Vibration-Resistant Setup Studs

Also known as tap-end and fixture studs, these rods have friction-fit threads on one end to resist loosening and standard threads on the other side for attaching a nut.

Quick-Clamping Coil-Threaded Rods, Screws, and Nuts

Combine fast-threading components to build a clamping assembly.
