360 degree Caster Wheel for Robotics Car

360 Degree Caster Wheel for Robotics Car is a compact, omnidirectional balance wheel designed to provide smooth multi-directional support for 2WD (two-wheel drive) mobile robots and smart car chassis setups. Functioning as a passive third point of contact, this swivel caster allows the primary drive wheels to execute differential turning, zero-radius pivots, and smooth directional adjustments without adding friction or resistance. Engineered with a durable metal or solid nylon ball mounted inside a smooth housing, it is an essential hardware component for stable robotic navigation.

Features

• 360-degree free rotation delivering frictionless omnidirectional movement in all directions
• Low-profile design ensuring proper chassis height alignment with standard 65mm TT motor wheels
• High mechanical stability with minimal rolling friction to prevent motor strain and battery drain
• Pre-drilled metal or durable plastic mounting plate for quick installation using standard M3 screws
• Dual ball-bearing or smooth steel/nylon swivel mechanism ensuring smooth steering response
• Excellent load-bearing capability suitable for lightweight to medium-weight robot chassis
• Durable, wear-resistant construction designed for long-term use on smooth indoor surfaces
• Plug-and-play balance wheel for Arduino, ESP32, and Raspberry Pi 2WD mobile platforms

Applications

• 2WD autonomous smart robot car chassis (Arduino, ESP32, ESP8266, Raspberry Pi)
• Line-following, maze-solving, and obstacle-avoiding mobile robotics platforms
• Balance wheel for differential drive rovers, vacuum robots, and inspection bots
• Remote-controlled (RC) toy vehicles operating via Bluetooth, Wi-Fi, or RF modules
• Microcontroller-based educational STEM projects, polytechnic diploma coursework, and university robotics labs

Important Notes:

• Mounting height must be level with the driven wheels; use spacers or standoffs if needed to keep the chassis parallel to the ground.
• Keep the caster ball and internal race free of dust, hair, or debris to maintain smooth 360-degree rotational movement.
• Do not exceed the maximum load rating of the caster wheel to prevent deformation of the internal ball housing.
• Secure the mounting plate firmly using M3 nuts and bolts to prevent loosening from chassis vibrations during movement.
