4" Smush Wheel

The 4" Smush Wheel is a high-performance, soft-contact roller engineered for FRC mechanisms that demand superior grip, controlled compression, and dependable object handling. Made from a durable, flexible rubber compound, the wheel deforms smoothly under load, allowing it to maintain continuous contact with game pieces while absorbing shock and reducing system vibration.

The increased diameter provides a larger contact patch and improved energy transfer, making the 4" Smush Wheel ideal for primary intakes, conveyor systems, indexing paths, and object centering applications. Its compliant spoke geometry enables the wheel to conform to uneven shapes, ensuring consistent performance even at high speeds or with rapidly changing loads.
