Machinable-Bore Sprockets for ANSI Roller Chain
For a custom fit on your shaft, these sprockets can be machined to your exact specifications. They come machined to the shaft diameter size listed and are machinable up to the maximum shaft diameter size.

Lightweight Sprockets for ANSI Roller Chain
Made of nylon, these sprockets are lightweight, quiet, and corrosion resistant. 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.
Quick-Grip Screw-Clamp Bushings
Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed. As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.
Stainless steel bushings are corrosion resistant for use in harsh environments.

Light Duty Sleeve Bushings
Reduce the ID of sprockets, pulleys, and gears in low-torque applications. Bushings have a hole for a set screw.

L Series Timing Belt Pulleys
Pulleys are L series (light) and have trapezoidal teeth. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

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.

Metal Worms and Worm Gears
Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle. They transmit motion from worm to gear and cannot be reversed. For gears and worms to mesh correctly, they must have the same pressure angle and pitch/module. These worms are compatible with plastic worm gears.
Speed ratio is the ratio by which output shaft speed is reduced. As speed decreases, torque increases.
Cast iron gears are strong and durable.
