Replacement Parts Robotics Caster Ball Set with Durable Steel Bearings, 4 Sets 8 Pieces for EV3

Replacement pivot ball and caster set for educational robotics and hobby builds. Each pack contains 4 sets (8 pieces) of precisionfit pivot balls with steel bearings designed as direct replacements for part 2000702. These components restore smooth movement, reduce wobble, and extend the life of EV3, Boost, Creator, and MOC projects. Key benefits Reliable solution: worn or lost pivot balls and casters quickly to get robots and models moving again without rebuilding the chassis. Smooth, consistent motion: Steel ball bearings provide lowfriction rolling for steadier turns and less binding during movement. Direct fit and easy install: Engineered to match part 2000702 dimensions for straightforward installation into compatible kits and custom builds. Durable performance: Metal ball construction resists flattening and wear compared to plasticonly alternatives, improving uptime for classroom and hobby use. Value and convenience: Four complete sets per pack means you have spares for multiple projects or classroom stations.
