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.

These aluminum billet wheels are the perfect replacement for plastic molded wheels used on other COTS swerve modules like the REV MAXSwerve.

Features include:

• Utilizes 1" Wide Tread giving you the maximum contact patch possible with the floor. Testing has shown good tread wear under multiple hours of driving.
• Includes eight #10-32 1/2" long button head bolts to attach tread quickly and easily. We recommend 3D printing this Tread Template tool to help cut tread to size and with drilling holes
• Eliminates need for adapter plate reducing part count overall.

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.

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

Affordable and durable 2 inch squish wheels are now available. These wheels are commonly used by competitive robotics teams to move game pieces throughout their robot.

These wheels ship in packs of 10 and feature:

• 30A durometer TPE rubber material for maximum squishability
• .375 inch hex hole, intended to be stretched and used on 1/2 inch hex shafts or other larger OD tubes. Each wheel is 1/2 inch thick.
• Weight: .038 lbs per wheel

1 inch wide, 10 foot long length of black 3 ply neoprene rubber tread. This tread is the same as 5994K1 but is already cut to a convenient 1 inch width. Nominal thickness is .30 inches. Weight of a spool is 1.13 lbs

1.5 inch wide, 10 foot long length of black 3 ply neoprene rubber tread. This tread is the same as 5994K1 but is already cut to a convenient 1.5 inch width. Nominal thickness is .30 inches. Weight of a spool is 1.77 lbs

The original vectored intake wheel, now with even more options. This wheel design was battle tested and match proven on many FRC robots during the 2020 season. These wheels help with redirecting game objects while imparting lateral force, helping to move game pieces either left or right in the direction you desire.

These x-contact bearings are commonly used in swerve drive applications by FRC teams.

Dimensions are 4" OD x 3.5" ID x .25" thick.

Weight is 2.5 ounces or .156 lbs.
