Detailed Description:

The Robot Wheel 7 x 2 CM is a fundamental and reliable component for anyone building a mobile robot or smart car. Specifically designed for DC geared motors, this wheel provides the perfect combination of durability and functionality for hobbyists, students, and engineers. Its standard dimensions, with a 7cm (70mm) diameter and a 2cm (20mm) width, offer an excellent balance of speed and stability, making it a versatile choice for a wide array of projects.

A key technical feature of this wheel is its construction. It is made from a high-quality, durable plastic hub fitted with a thick rubber tyre. This rubber tyre is crucial for providing superior traction and grip on various surfaces, from smooth indoor floors to more challenging outdoor terrains, ensuring your robot maintains stable and reliable movement. The wheel's hub is engineered for a secure and straightforward connection to a motor shaft. With a standard 6mm shaft bore and a built-in screw, it fits snugly onto most standard DC geared motors, eliminating the need for separate couplers and simplifying the assembly process. This easy-to-mount design is perfect for beginners and speeds up prototyping for more complex projects. Whether you are creating a line follower, an obstacle avoidance robot, or a custom-built drone, this rubber tyre provides the high-traction performance you need.

The 7x2 cm (70mm x 20mm) robot wheel is designed for DC geared motors with 6mm D-shaped shafts. It features a high-traction rubber outer layer and a durable plastic hub, offering excellent grip on a variety of surfaces.

Ideal for 2WD and 4WD mobile robots, this wheel is widely used in Arduino robotics kits, smart vehicle models, and automation platforms. The strong mechanical fit ensures smooth movement and stable handling in dynamic robotic applications.
