Standard 20DP Gears 1/2 in Hex, 36 Tooth

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 novel style of collar clamp is split into two pieces so that it can be attached without removing any shafts. The bore is a 1/2" hex. The flats on the perimeter allow for the collar clamp to be held in position or turned for better assembly control. 

This clamp has been designed and fabricated by BaneBots, and proudly sold through AndyMark.

Specifications:

• Material: Aluminum
• Bore: hex hole, 1/2 inch
• Outside Diameter: 0.94 inch
• Thickness: 0.375 inch
• Width Across Flats: 7/8 inch
• Weight: 0.020 pound
• Clamping Screws: #6-32 x 1/2" long (qty. 2)

Plastic spacers are included with this clamp, positioned between the two halves. These are to be removed before usage.

Whether you have shafts that are too short or shafts of different types, this coupling will solve every component connection issue you've had! Need to combine multiple hex shafts, multiple 1/2-inch keyed shafts, or convert between hex and keyed? This coupling solves all at a better price than anyone else can offer!

Shaft Compatability

This coupling has geometry to capture 0.50-inch hex shafts with an inside hex of 0.51 to 0.52 inches as well as 0.5 inch keyed shafts with a 1/8th inch keyway with a keyway width of 0.128 inches to 0.131 inches.

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.

Our SpinTake has three bore options, making it a viable part for both FRC and FTC! This product is ideal as an intake "wheel" for picking up game pieces of varying shapes. Made from natural rubber, the SpinTake is flexible, yet firm. Its unique shape also allows it to be oriented to stay within the robot frame perimeter initially but can reach outside just by spinning. These work in a similar fashion to surgical tubing fingers on an axle, but are easier to implement and provide a cleaner look with more consistent results. 

The Hex Bore options are designed to be an interference fit on their associated Hex Shafts. This means it will be a tight press to install but will resist slipping under load. 

Specifications

• Bore: 5 mm Hex, Nub Bore, 1/2 in. Hex
• Length (Diameter): 3 in.
• Material: Natural Rubber
• Thickness: 0.5 in.

These are all of our 9 mm wide 5 mm pitch HTD synchronous timing belt offerings. All of these belts are a composite of flexible rubber with a fiberglass tensile member throughout. Synchronous timing belts, also known as a toothed belt or synchronous belt, are designed to eliminate slippage and keep any number of objects rotating at a constant rate. We offer both genuine Gates brand belts as well as lower-cost generic brand belts. 

Compliant Stars are the perfect thing for intake mechanisms. The soft material gives way to allow rigid objects to be manipulated easily. A line of multiple stars on a driven hex shaft creates a very effective roller that ignores variations in the objects being driven. The multiple-spoke design allows the star to act as a brush, creating more surface area to interact with and grab objects. This makes for high-performance intakes and internal conveyors. A shaft collar may be used to make absolutely sure the wheels stay clear of other mechanisms or maintain consistent spacing. Molded into the star are several guidelines. Cut the star at the lines (or elsewhere) to create more compact mechanisms. 

Different durometer ratings give each Compliant Star unique characteristics. Green stars (35A durometer) are the softest and most compliant around objects, while orange (40A), maroon (45A), and blue (50A) wheels are increasingly firm. Black (60A) is quite firm, while the Gray (80A) is nearly rigid. The increased firmness also allows the latter wheels to carry a higher RPM rating
