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

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 8mm keyed bore or spline bore depending on the motor type you're using.

These are 3" OD x 2.5" ID x .25" x-contact thin section bearings, commonly used in small swerve drive modules by FRC and FTC teams.

Dimensions are 3" OD x 2.5" ID x .25" thick.

Weight is 1.9 ounces or 0.119 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

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 8mm keyed bore or spline bore depending on the motor type you're using.

These are 3.5" OD x 3.0" ID x .25" x-contact thin section bearings, commonly used in small swerve drive modules by FRC and FTC teams.

Dimensions are 3.5" OD x 3.0" ID x .25" thick.

These crowned roller pulleys are designed to fit over 1.25" OD tubing. They are made from 70A durometer TPE and are great for keeping flat urethane belting centered on your tubes or for simply intaking game pieces using the rollers themselves.

Holes are included for 5/32 rivets that can be used for retention on tubes. Rivets nest nicely within the TPE material, leaving the rivet head slightly below the rest of the roller material.

2.875" in length, 1.6" OD at center

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.

This is a 1.5" thick 45A durometer urethane wheel with a half inch hex bore. Great for accelerating game objects or for when low compression is desired. 4 inch outer diameter.

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 for $3 per wheel 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
• STEP CAD file available

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 bearing options are perfect for supporting spline shafts. The bearings slide on easily in our testing.

Flanged version: 35mm ID x 47mm OD x 7mm overall width - 1.5mm thick flange - .070 lbs

Radial version: 35mm ID x 47mm OD x 7mm overall width - .065 lbs

Comes in both radial and flanged versions.

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.

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.
