Machinable-Bore Corrosion-Resistant
Sprockets for Metric Roller Chain

Machine the center of these sprockets to fit the exact dimensions of your shaft. They come machined to the shaft diameter size listed and are machinable up to the maximum shaft diameter size. The teeth are sized to fit into metric ISO roller chain. Made from stainless steel, they won’t corrode from humidity or frequent washdowns. The extended hub makes these sprockets more stable and more durable than sprockets with flat hubs. They meet ISO 606 (formerly DIN 8187), which is an international standard for dimensions and materials.

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.

Sprockets for Double-Strand Metric Roller Chain

The double row of teeth on these sprockets are designed to fit into metric ISO double-strand roller chain. They have an unfinished bore that’s machined to the shaft diameter size listed. Machine them to fit any shaft up to the maximum shaft diameter size. The extended hub makes these sprockets more stable and more durable than flat sprockets. They meet ISO 606 (formerly DIN 8187), which is an international standard for sprocket and roller chain dimensions and materials.

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.
