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.

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.
