About Roller Chain and Sprockets

About Gears

Designed to meet ISO 606 and DIN 8187 international dimensional standards, these sprockets are for use with compatible ISO and DIN roller chain. They come machined to the shaft diameter size listed and are machinable up to the maximum shaft diameter size.

Flat Sprockets for Metric Roller Chain

With metric teeth and slim profile, these sprockets allow your ISO roller chain to reach narrow spaces. They're commonly referred to as A-plate sprockets. Machine the unfinished bore to fit your shaft—sprockets come machined to the shaft diameter listed and are machinable up to the maximum shaft diameter size. Sprockets meet DIN 8187 and ISO 606, international standards for sprockets and roller chains.

Taper-Lock Bushing-Bore Sprockets for Metric Roller Chain

While their teeth fit into metric ISO roller chain, these sprockets use taper-lock bushings to grip shafts. That means you can switch to a different diameter shaft by changing the bushing instead of machining the sprocket. Bushings mount flush inside these sprockets; secure them in place by tightening the set screws included with the bushings. These sprockets have an extended hub that makes them more stable and durable than flat sprockets. All meet ISO 606 (formerly DIN 8187), which is an international standard for sprocket and roller chain dimensions and materials.

High-Strength GT Timing Belt Pulleys

For higher speed or higher torque applications, these GT series timing belt pulleys provide a more precise fit than HTD pulleys. Use them where accuracy is critical, such as in storage and retrieval systems or in robotics. Similar to HTD timing belt pulleys, their teeth are curved for high strength. The curved teeth create positive grip engagement with timing belts, so these pulleys do not require re-tensioning—unlike drives using V-belts or sheaves. And unlike chain drives, there’s no metal-on-metal contact, so these pulleys don’t require lubrication.

Metal Gears and Gear Racks—20° Pressure Angle

The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Compared to plastic gears and racks, they’re better for high-load, high-speed, and heavy duty applications. Also known as spur gears.

Combine gears with different numbers of teeth to change speed and torque in your assembly. Combine a gear and rack to convert rotary motion into linear motion. To minimize your footprint, mount one or more standard gears inside of an internal gear.

For components to mesh correctly, they must have the same pressure angle and pitch/module.

Brass gears and racks are easy to machine, so you can add your own mounting holes and make other alterations. They won't rust when exposed to water.

Gears with teeth that are not hardened can be hardened to fit your application.

Stainless steel gears and racks resist rust in damp and wet environments, so they're commonly used in food-processing plants and other areas with frequent cleaning. Gears with a clamping bore have a built-in clamp that securely grips shafts without marring them. Use the included clamping screw to tighten or loosen the grip.

Metal Bevel Gears

Gear and Pinion Sold Separately

Gear

A type of miter gear where one gear (sometimes called a pinion) is smaller than the other, bevel gears provide right-angle speed reduction at speed ratios ranging from 2:1 to 5:1. All are carbon steel for strength; they're compatible with plastic bevel gears. Teeth are not hardened so you can harden them to fit your application. Hardening a gear’s teeth increases its wear resistance.

A complete set consists of a gear and pinion (sold separately). For a gear and pinion to mesh correctly, they must have the same pressure angle, pitch/module, and face width. Speed ratio is the ratio by which shaft speed is reduced when transferring motion from pinion to gear. To increase shaft speed, transfer motion from gear to pinion. Changing shaft speed also changes torque: as speed decreases, torque increases.

Plastic Gears and Gear Racks—20° Pressure Angle

The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Made of plastic, they run quieter than metal gears and have good corrosion and chemical resistance. They’re also known as spur gears.

Combine gears with different numbers of teeth to change speed and torque in your assembly. Combine a gear and rack to convert rotary motion into linear motion.

For components to mesh correctly, they must have the same pressure angle and pitch/module.

Acetal gears are best suited for use in light duty machines or for prototyping. Gears with a clamping bore secure to shafts with a clamping screw. They’re easily removed or adjusted without marring your shaft.

Plastic Gears and Gear Racks—14 1/2° Pressure Angle

A former industry standard, 14½° pressure angle gears are often found on older machinery. Made of plastic, they run quieter than metal gears and have good corrosion and chemical resistance. They’re also known as spur gears.

Combine gears with different numbers of teeth to change speed and torque in your assembly. Combine a gear and rack to convert rotary motion into linear motion.

For components to mesh correctly, they must have the same pressure angle and pitch.

Metal Ratcheting Gears

Pawl and Gear Sold Separately

Compared to plastic gears, these metal ratcheting gears are better for high-load, high-speed, and heavy duty applications. Used to prevent unwanted motion in jacks, tie downs, clutches, and winches, ratchet gears have sloped teeth that allow motion in one direction and prevent it in the other. Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear’s teeth increases its wear resistance.
