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.

Flat Taper-Lock Bushing-Bore Sprockets for Double-Strand Metric Roller Chain

With a slim profile and a double row of teeth, these sprockets allow your metric ISO double-strand roller chain to fit into tight spaces. They’re often called A-plate sprockets. To grip shafts, they use taper-lock bushings, so 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. All of these sprockets meet ISO 606 (formerly DIN 8187), which is an international standard for sprocket and roller chain dimensions and materials.

Taper-Lock Bushings

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing style. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.

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. Shaft-mounted pinions come already securely fastened to a shaft.

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 Bevel Gears

Gear and Pinion Sold Separately

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. Because they’re self-lubricating, these bevel gears are commonly used in food machinery. They should not, however, come in direct contact with food or chemicals that will come in contact with food.

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, module, and face width. Plastic pinions can also be mated with metal gears, and plastic gears with metal pinions.
