High-Torque HTD Timing Belt Pulleys
 |  |

 |  |
Bushing Bore |
Curved teeth engage with the matching belt better than standard trapezoidal teeth, so these pulleys transmit about twice the torque. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP series.
Iron—Strong but best for dry environments since moisture will cause them to rust.
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.
Corrosion-Resistant Stainless Steel—Stands up to wet environments and mild chemicals, such as the ammonia in cleaning solutions.
Finished Bore—Mount these pulleys onto the shaft and secure with a set screw—no machining required.
Plain Bore—Do it your way—machine the bore to your exact shaft size or add a set screw or keyway.
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.

High-Torque HTD Timing Belt Pulleys for Hex Shafts
 |
|
No need for set screws—these pulleys have bores with six walls that engage with the shaft to transfer torque. They're a good choice when your setup needs to come apart frequently since there aren't extra mounting steps such as press fitting or installing bushings. These pulleys have curved HTD teeth that interlock with the matching belt better than trapezoidal teeth, so they transmit about twice the torque. All are compatible with Gates PowerGrip HTD, Omega HP, and Carlisle RPP 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.
