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.

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 Miter Gears

Gears Sold Separately

Connect two shafts at a right angle without changing shaft speed or torque. Made of plastic, these gears run quieter than metal gears and have good corrosion and chemical resistance.

For two gears to mesh correctly, they must have the same pressure angle, pitch/module, and number of teeth.

Nylon gears are self-lubricating, so they’re often used in food machinery. However, they’re not approved for direct contact with food or chemicals that will come into contact with food.
