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

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.
