Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Connecting Rods

Connecting Rods

Use with rod ends and swivel joints to link components in push/pull assemblies

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Ball Screws and Nuts

Ball Screws and Nuts

Internal ball bearings roll on screws for low friction when moving components at high speeds

Gear Stock

Machine your own gears to an exact face width and shaft diameter

Gears and Gear Racks

Gears and Gear Racks

Connect two rotary shafts to change a system's speed, torque, and angle

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Ball Screw/Splines

Ball Screw/Splines

Transmit rotary power, move loads along the shaft, or do both at once

Flexible Shafts

Flexible Shafts

Snake around curves and obstructions to transmit rotary motion along any path

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Chain and Belt Pulley Stock

Chain and Belt Pulley Stock

Machine your own timing belt pulleys to fit an exact width and shaft diameter

Roller Screws and Nuts

Roller Screws and Nuts

More contact points to move heavier loads than ball and lead screw assemblies

Raw Materials

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Aluminum

Lightweight, easy to machine, and corrosion resistant in wet environments

Plastic

A lightweight alternative to metal and glass

Brass

More machinable than copper and bronze for making nuts, hinges, and locks

Bronze

With better wear resistance than copper and brass, it’s used for bearings, gears, and pump parts

Garolite

A strong, machinable alternative to metal and plastic widely used in circuit boards and gears

Tungsten

Our densest metal resists wear and heat to make end mills, heat shields, electrodes, and more

Carbon Fiber

The strongest composite we offer; comparable in strength to 6061 aluminum but lighter in weight

Titanium

The most corrosion-resistant metal we offer, with very high strength relative to its weight

Copper

The most conductive of our metals, it excels in all types of electrical applications

Fiberglass

A lightweight alternative to metal and wood widely used in electrical and structural applications

Ceramic

Hard and wear resistant, it also withstands corrosion and high temperatures

Nickel

An upgrade from stainless steel that withstands harsh chemicals and acids at high temperatures

Cobalt

Slides against other materials without wearing and sticking; resists impact and rapid temperature changes

Hard Fiber

Chemically treated to be hard and dense, this is the easiest composite to machine in our offering

Lead

A dense insulator often used to shield against radiation and absorb sound and vibration

Molybdenum

Retains its shape and strength in extreme temperatures and conducts heat and electricity

Gold

Softer than copper and nearly as conductive, form it into electronic components that won't corrode

Platinum

Conductive and formable, it resists extreme heat for use in parts such as thermocouple probes

Kevlar

Super tough for protection against prolonged wear and abrasion

Niobium

Conductive, corrosion resistant, and strong, even at extremely high and low temperatures

Zinc

Draws corrosion away from nearby metal; an alternative to lead for sound barriers and vibration dampers

Tantalum

Conductive with a higher melting point than most metals, it’s often used in heating elements

Fastening and Joining

Dowel Pins

Align parts before assembly or use as a pivot, shaft, or hinge to join moving components

Dowel Pin Stock

Dowel Pin Stock

Cut to the length you need for positioning and holding parts in place

Single-End Studs

Single-End Studs

Use the unthreaded end as a pivot point, hinge, shaft, or locator pin

Threaded Rods

Anchor, connect, or hang components in a wide variety of applications

Studs

Press, weld, or screw in place to add a threaded fastening point

Thread Adapters

Thread Adapters

Join threads of a different type, size, and gender

Standoffs

Threaded to separate or connect parts as well as position components in assemblies

Driver Shafts
