Item Type: Omni Wheel Material: Neoprene Model: P56466 Center Hole: Approx. 8mm / 0.3in Diameter: Approx. 100mm / 3.9in Purpose: By using omnidirectional wheels with 10 driven rubber rollers, the robot can perform 360 maneuverability and rotation functions, including lateral movement and diagonal movement Package List 1 x Omni Wheel 1There are 10 balancedly distributed driven wheels around the omni wheel, and they are installed and fixed by steel shaft with diameter of 3mm. 2The driven wheel is made of neoprene, which can reduce the friction generated during rotation and run more quietly. 3When the omni wheel is used in pairs, the outline becomes circular so that as the wheels rotate, the load can be seamlessly transferred from one wheel to the other. 4Commonly used in robots, it can perform 360 maneuverability and rotation functions, including lateral and diagonal movement. 5The diameter of the omnidirectional wheel is 100mm, the central aperture is 8mm, and the size is standard for easy installation.
