Machine the center of these sprockets to fit the exact dimensions of your shaft. The teeth are sized to fit into metric ISO roller chain.

The double row of teeth on these sprockets are designed to fit into metric ISO double-strand roller chain.

A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket.

Pulleys are anodized aluminum, which is more corrosion resistant than steel.

Acetal and aluminum construction makes these pulleys useful in for weight-sensitive applications.

For smooth, quiet operation at high speeds under heavy loads, helical gears have curved teeth that engage gradually and stay in contact longer than straight teeth.

Worm gears use screw threads to reduce shaft speed by ratios of 10:1 and greater while transmitting motion at a right angle.

A type of miter gear where one gear is smaller than the other, bevel gears provide right-angle speed reduction at ratios ranging from 2:1 to 5:1. They’re more efficient than worm gears because they create less friction.

These plastic gears are lighter and quieter than metal gears—pair them with metal worms for lubrication-free operation. Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle.

Reduce speeds where noise, corrosion, and frequent lubrication are a concern. Compared to metal gears, these nylon gears run more quietly, won't rust, and don't need to be lubricated.
