The Thrifty Bushing - QTY 10

Tired of hex clamp collars that cost an arm and a leg? Tired of stripping out the set screw on your clamp collar? Need to add a collar in an assembly and don't want to remove everything from your hex shaft?

Me too! I've ran into all of the above scenarios multiple times building multiple robots. These collars are the holy grail -

• split so they can easily be added or removed
• lightweight 6061 aluminum
• .5 oz (.031 lbs) for one hex collar
• uses two 8-32 socket head cap screws that require a 9/64" allen wrench
• $4.00 per collar, sold in 5 packs
• anodized black for awesomeness

General Dimensions:

• When clamped on 1/2 inch hex shaft - approx 1.2 inch outer diameter
• 0.40 inches wide
• STEP file CAD Model Available

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 product includes two 1.25 inch long half inch hex couplers. This product has been verified to clamp all the various standards of 1/2" hex, rounded hex and AM churro with significant clamping force.

• 1.25" long overall - shortest hex coupler on the market.
• Split half design allows you to easily remove or add the coupler back on - great for mechanisms that might require maintenance or replacement.
• Each coupler includes four 3/8" long 6-32 threaded black oxide steel bolts. These bolts use a 7/64" driver to prevent easily stripping the bolt heads out.
• .1 ounces or .0625 pounds, black anodized 6061 aluminum.

Half inch hex hubs are often used to transfer motion between components in competition robots. This hub includes a thicker quarter inch flange that allows for tapping 10-24 / 10-32 holes or drilling and tapping to 1/4-20 sized holes. The Thrifty Hub is offered as a blank hex hub to teams to do further machining or leave stock as-is.

Note: Molded plastic cases have begun shipping with all encoder orders!



The Thrifty Absolute Magnetic Encoder was designed to provide teams a lower cost option for absolute position sensing. Simply plug the included 3-wire PWM style cable into your controller of choice and read the included magnet's absolute position. This device can connect directly to the RoboRIO as well as the REV Spark Max or CTRE Talon SRX.

Encoder Revision Updates Include -

• Switched to through hole connector to improve strength and assembly
• Cases are produced in ESD safe materials
• A J2 jumper spot has been added. Simply solder the jumper spot and the encoder will run in 3.3v mode. See the user guide for more details.

The Thrifty Clamping Bearing Block provides teams a quick and easy way to capture 1.125" OD flanged bearings when mounting to 2" x 1" or 1" x 1" box extrusion. Simply drill a pass thru clearance hole and insert the bearing which is then trapped against the extrusion wall's material.

Features include -

• Clamps around 2" x 1" or 1" x 1" extrusions
• Two counterbored 10-32 holes 2" apart allow for mounting of planetary gearboxes or 2" bolt circle motors
• #8 holes on a 1.875" diameter bolt circle allow for usability in existing FRC applications
• 6061 Aluminum material anodized black

Kit includes:

- Two black anodized plates

- Four 10-32 1.5" long button head bolts

- Two 10-32 0.50" long bolts

Bearings are NOT included with this kit

Mount all the things with this latest offering from The Thrifty Bot! Finally a plate that can interface with just about any common motor or planetary gearbox in the FIRST Robotics Competition. This 4mm thick 6061 aluminum black anodized plate includes bolt mounting patterns for the following motors and planetary gearboxes:

- REV Ultraplanetary Gearbox

- REV NEO 550 & Banebots 550 Brushed motors

- VEX Versaplanetary and Versaplanetary Lite gearboxes

- AndyMark 57 Sport planetary gearboxes

- 775 series brushed motors

- REV NEO & Falcon 500 brushless motors

- Traditional Mini-CIM & CIM motors

- 4mm thick (.157") allows for stronger cantilevered applications

- 1/4" hole to hole spacing, 1/2" spacing between hole rows. Holes are .164" natively supporting #8 bolts or 5/32 rivets. Holes can be drilled out to support #10 hardware.

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.
