The AndyMark 4in. BB Mecanum Wheel 0.375in. Hex Bore Left is a lightweight and slim wheel designed for smooth motion, thanks to the ball bearings within each roller. This wheel is particularly optimized for use in FTC chassis systems, such as the MecanAM Chassis. It is sold as an unassembled kit and is essential for creating a Mecanum drive holonomic system, which requires a specific configuration of 'right' and 'left' wheels to function correctly.
The wheel features a robust structure with 12 rubber rollers sandwiched between two steel plates, ensuring durability and stability. The rollers are made of black TPU rubber with a durometer rating of 60A, and they ride on a stationary brass tube, providing a smooth and reliable performance. The polycarbonate core of the rollers adds to the wheel's lightweight nature, making it suitable for light-duty applications, such as FTC robots or non-drive train FRC items.
This wheel is compatible with various attachment points, including Nubs, and can be directly driven using a 3/8 in. hex shaft. The wheel's design allows for easy integration into existing systems, making it a versatile choice for robotics applications.
