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.

Quick-Disconnect (QD) Bushings


The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

Self-Centering Screw-Clamp Bushings


A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket. They are also good for shock loads. When you tighten the included screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.
Plastic Bevel Gears

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.
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.
