Swivel Caster Wheels for Robot Car 1 Inch

These 1-inch swivel caster wheels are the perfect support solution for two-wheeled robots and mobile robotics platforms requiring a third point of stability. Featuring 360-degree full rotation capability, these universal caster wheels automatically align in the direction of movement, providing smooth and effortless navigation across various surfaces. The dual roller bearing design ensures minimal friction and superior durability for extended operation.

Constructed with high-quality white nylon PP material wheels and a robust steel mounting frame, these caster wheels deliver excellent load-bearing capacity of up to 10kg while maintaining a lightweight profile. The off-center wheel mounting on the swivel plate allows for natural directional alignment, reducing drag and enabling precise turns. The sleek silver metal frame complements any robot design, making them ideal for educational robotics, hobby projects, Arduino-based smart cars, and line-following robots.

Each wheel comes mounted on a metal plate with pre-drilled M4 mounting holes for easy installation on any robot chassis or project platform. Whether you’re building a balance bot, obstacle-avoiding robot, or automated guided vehicle, these support wheels provide the stability and mobility your project needs. Perfect for students, hobbyists, makers, and robotics enthusiasts looking for reliable, cost-effective support wheels for their mobile platforms.
