Finished Bore | Plain Bore |
Sprocket teeth mesh with your roller chain to smoothly transmit power. These U.S.-made sprockets have machined teeth for a more precise fit than flame-cut or punched teeth, allowing them to glide in and out of the chain to reduce wear and extend chain life.
Steel—Steel is strong, but best for dry environments since moisture will cause it to rust.
Finished Bore—Mount these sprockets onto your shaft and secure with a set screw—no machining required.
Plain Bore—Plain bore sprockets give you options—machine a custom bore, weld, or press-fit them in place. They're sized to the minimum shaft diameter listed and are machinable up to the maximum.

Ultra-High-Torque GT Timing Belt Pulleys
 |
 |
Pair these pulleys with the strongest timing belts we offer, Ultra-High-Torque GT Timing Belts. They can handle as much torque as roller chain. Their curved teeth fit snugly with matching belts for minimal play (backlash), so these pulleys are good for applications that require precise positioning. All are compatible with Gates Poly Chain GT timing belts.
Iron—Strong but best for dry environments since moisture will cause them to rust.
Bushing Bore—Quickly swap or service parts in tight spaces—no press-fitting or special tools required. Mount a bushing (sold separately) on your shaft and slide the pulley over it. As you tighten the included set screws, the bushing grips the shaft and draws it into the pulley, creating a final hold that is more secure than with set screws alone.

Metal Bevel Gears
High-Load Metal Spiral Bevel Gears
 |
Gears Sold Separately |
 |
Large Gears |
The spiral teeth on these bevel gears stay in contact longer than straight teeth, so they can handle heavier loads at higher speeds. Use them to transmit motion at a right angle while changing shaft speed and torque. Their teeth engage gradually, which reduces vibration and noise, and they’re hardened for extra wear resistance. All are carbon steel for good strength. They have a machinable bore, so you can customize the size within the For Shaft Diameter range listed.
A complete set consists of a large gear and a small gear, also known as a pinion (sold separately). For the gears to mesh correctly, they must have the same face width, pitch or module, and pressure angle.
Speed Ratio—The ratio by which shaft speed is reduced when transferring motion from the smaller to the larger gear. To increase shaft speed, transfer motion from the larger to the smaller gear. Changing shaft speed also changes torque: as speed decreases, torque increases. To achieve the speed ratio listed, match it across a set of compatible gears.

Precision High-Torque GT Timing Belt Pulleys
 |
Finished Bore |
|
When precise synchronization is crucial, these pulleys minimize play (backlash). They’re often found in 3D printers, where accurate positioning is essential. Their curved teeth fit snugly with matching belts. Compared to pulleys with standard trapezoidal teeth, these pulleys transmit about three times more torque and run at higher speeds. All are compatible with Gates PowerGrip GT, 2GT, GT2, GT3, and GT4 series.
Corrosion-Resistant Aluminum—Won't rust in wet environments and one-third the weight of steel and iron. However, aluminum pulleys are not as strong as iron and steel.
Finished Bore—Mount these pulleys onto the shaft and secure with a set screw—no machining required.
