Arcade manufacturers employ rigorous testing methods to ensure the long-term durability of trackballs and spinners, critical components in arcade gaming. These tests simulate real-world usage to guarantee reliability and performance.

For trackballs, manufacturers often use automated rolling machines that mimic continuous player input over thousands of hours. The trackball's bearings, surface material, and internal mechanisms are monitored for wear and tear. High-quality trackballs are tested for millions of rotations to ensure smooth operation.

Spinners, commonly found in racing and puzzle games, undergo similar endurance testing. Machines simulate rapid spins and abrupt stops to evaluate mechanical stress. Components like optical encoders and bearings are checked for degradation over time.

Environmental factors, such as dust and humidity, are also tested to replicate arcade conditions. Manufacturers may use accelerated aging techniques to predict long-term performance.

By combining mechanical stress tests, environmental simulations, and quality control checks, arcade manufacturers ensure their trackballs and spinners withstand years of intense gameplay.
