Lock bearings in place on a shaft for precise positioning

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

Gears and Gear Racks

Gears and Gear Racks

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

Gear Stock

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

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Shaft Collars

Hold and position parts on a shaft, or limit shaft movement

Lead and Ball Screw End Supports

Lead and Ball Screw End Supports

Brace and secure the ends of lead screws and ball screws

Ball Screw/Splines

Ball Screw/Splines

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

Track Rollers

Support and carry objects as they move along conveyor systems

Roller Screws and Nuts

Roller Screws and Nuts

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

Chain and Belt Pulley Stock

Chain and Belt Pulley Stock

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

Electric Actuators

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

Tungsten

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

Plastic

A lightweight alternative to metal and glass

Cobalt

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

Carbon Fiber

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

Brass

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

Titanium

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

Garolite

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

Bronze

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

Lead

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

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

Hard Fiber

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

Copper

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

Niobium

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

Kevlar

Super tough for protection against prolonged wear and abrasion

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

Nickel

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

Building and Machinery Hardware

Drawer Slides

Smoothly guide drawers in and out of cabinets

Material Handling

Robot Positioning Slides

Robot Positioning Slides

Extend the horizontal reach of your Universal Robots arm
