This 5M HTD aluminum pulley 2 pack will allow teams to create larger single belt reductions with a common 1/2" hex interface.

This is the same pulley used on the Thrifty Elevator Dyneema Pulley Kit. Works great with 1/8" dyneema rope and has a 1/4" ID bearing in the center allowing teams to use a bolt to easily mount it and have it spin freely.

1.15" OD with a .365" groove will let this pulley work with other rope options as well.

These aluminum 5M HTD Pulleys work great for creating belt reductions directly off the motor. Use a 15mm wide belt or two 9mm wide belts as the inside pulley teeth are 18.5mm wide. Choose either Kraken SplineXS bore, 8mm keyed bore, or Falcon spline bore depending on the motor type you're using.

This 5M HTD aluminum pulley will allow teams to create belt reductions and drive mechanisms with a common 1/2" hex interface. We focused on robustness and tested them thoroughly during the 2024 season to ensure the flanges do not pop off during use.

- 18.5mm wide teeth allows for two 9mm belts or one 15mm wide belt

- Includes a small bump out to offset away from bearings.

This 48 tooth 5M HTD aluminum pulley will allow teams to create belt reductions and drive mechanisms using a hub interface or on a shaft. We focused on robustness and tested them thoroughly during the 2024 season to ensure the flanges do not pop off during use.

- 1.126" bore allows for teams to insert a hub, a bearing or a bushing depending on their application. This pulley gives you maximum flexibility for your mechanism designs.

- 18.5mm wide teeth allows for two 9mm belts or one 15mm wide belt

- Includes both 1.875" and 2" bolt circles to work either both standards.
