The Thrifty Hub - Half Inch Hex - QTY 4

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

Coral (also known as Game Piece 1) is a 11 ⅞ in. long (~30 cm) piece of 4 in. diameter Schedule 40 Cellular (Foam) Core PVC pipe. Coral has a 4-in. (~102 mm) inside diameter and a 4½-in. (~11 cm) outside diameter. The Coral sold here is from the same batch and manufacturer used on official fields. 

You asked, we listened! These 3" diameter HD (heavy-duty) solid-core Compliant Wheels are intended for manipulating objects where you need a little 'give' in your intake system. These wheels deform out of the way to allow rigid objects to be manipulated easily. This makes for high-performance intakes and internal conveyors. These wheels do not require the use of expensive hubs to be driven, thanks to their integrated high strength polycarbonate hubs - which are made from the same mold that creates our Hex Molded Spacers.

Different durometer ratings give each wheel unique characteristics. Green compliant wheels (35A durometer) are the softest and most compliant around objects, while maroon (45A) blue (50A) and black (60A) wheels are increasingly firm.

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.

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

Our Entrapption Stars have two bore options, making them viable parts for both FRC and FTC! This product is frequently used as intake wheels for picking up game pieces. Made from silicone, they are flexible, yet firm, allowing for the ability to pick up objects of irregular shape.

The 1/2 in. Hex Bore option is designed to be an interference fit on any 0.5 in. Hex Shaft.  This means the bore is actually 0.425 in. and it will be a tight press on, but keep the entrapption star from rotating.

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.

This item can only be purchased in multiples of 8

These solid polyethylene (PE) closed cell foam noodles are great for building bumpers for the FIRST® Robotics Competition.

This foam outperformed all other tested options when paired with a backing of Soft Tiles. 

A rough estimation is that about 6-8 pool noodles are used for 1 set of bumpers depending on robot size. Noodles are required to be purchased in multiples of 8. Read the robot rules to ensure you understand how to create legal bumpers based on this year's rules.

This is a Heavy Duty Hex Bearing which outperforms our previous 1/2" Hex Bearings as it has a Heavy Duty Inner Race. This FR8ZZ-HexHD bearing, 1/2" hex bore, flanged, heavy duty inner race, shielded ball bearing, has an inner race that is thicker and stronger than our recent offering of a similar bearing (am-0279). This bearing has more material between the corners of the hex bore and the edge of the race making it stronger and much less likely to crack under high load.

This bearing is guaranteed to have a stronger, thicker race. 100% of these bearings have been quality checked for a smooth fit over 1/2" hex stock here at AndyMark. Many of our long-time customers will recognize this bearing, as it is the same version we sold back in 2008-2011, and we did not have any failures. Now, it is renamed and quality checked for your high load needs - including drive chassis with cantilevered wheels.

Specifications:

• Inside diameter: 0.500-0.502 inch hex bore
• Outside diameter: 1.125 inch
• Flange thickness: 0.062 inch
• Overall thickness: 0.312 inch
• Weight: 0.05 pound

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
