Power Transmission

Shafts

Transmit power, motion, and speed between machine components

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Flexible Shafts

Flexible Shafts

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

Ball Screw/Splines

Ball Screw/Splines

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

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

Tungsten

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

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

Titanium

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

Carbon Fiber

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

Garolite

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

Copper

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

Ceramic

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

Cobalt

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

Fiberglass

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

Lead

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

Nickel

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

Hard Fiber

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

Molybdenum

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

Zinc

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

Kevlar

Super tough for protection against prolonged wear and abrasion

Niobium

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

Fluid Handling

Mixer Shafts

Replace the shaft on mixers

Safety Equipment

Rotary Shaft Covers

Rotary Shaft Covers

Protect exposed rotary shafts from debris and reduce the chance of injury

Building and Machinery Hardware

Control Cables

Weave around obstructions to operate valves, throttles, and other machinery from a distance
