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.

This new kit from Thriftybot allows you to drive 1.125" ID tubing in a number of ways. Using the Thrifty Metahub, plug into tubes and use your bearing bore of choice.

Kit includes all of the following - 

- QTY 2 Aluminum Thrifty Metahubs - 24 Tooth HTD pulley that support the following configurations -

QTY 2 - 1" OD needle roller bearings for 3/4" OD tubes

QTY 2 - 1/2" hex bearings for hex shafts

QTY 2 - 3/8" ID bearings and a custom hex spacer. Run a 1/4-20 bolt thru your external material and then slip the roller tube in to connect the two hubs together.

Note that this kit provides enough parts to create a full roller with aluminum hubs on each end.

Thriftybot suggests this polycarbonate tubing from McMaster-Carr.
