The Thrifty Bushing is a nylon bushing that works with 13.75 mm diameter style hex shaft. This bushing is recommended for low-load applications and will allow you to package mechanisms into even smaller form factors. Thriftybot recommends greasing bushings prior to use.

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.
