About Roller Chain and Sprockets
More
Sprockets for Metric Roller Chain
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.
For technical drawings and 3-D models, click on a part number.
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.

Timing Belt Idler Pulleys
Add these free-spinning pulleys to your timing belt setup to minimize vibration and keep belts from wearing out. The needle bearing at the center of these pulleys is lined with small, cylindrical rollers that reduce friction as they rotate. This bearing allows both the pulley and the shaft it’s mounted on to spin independently. Made from iron or steel, these pulleys are strong and wear-resistant. The black oxide coating protects the pulleys from corrosion in dry environments.
Trapezoidal teeth on the outside of the pulley fit into teeth inside your timing belt—select a pulley that matches your belt trade size. The maximum belt width should be the same size or larger than the width of your timing belt.
