When should O-rings be replaced in FANUC robots?

When should O-rings be replaced in FANUC robots?

• A. Every six months
• B. Whenever they are removed from the robot
• C. Only when they are damaged
• D. After every mission

Answer: (B)

O-rings should be replaced whenever they are removed from the robot to ensure the integrity of the sealing mechanism. This practice is essential because O-rings can become deformed or compromised during the assembly and disassembly process. Even if they appear to be in good condition visually, the act of removal can create micro-damages or alter their sealing properties, leading to potential leaks or failures when reinstalled. Thus, replacing them during maintenance enhances the reliability of the system and helps prevent issues that could arise from reusing old or potentially damaged seals. Maintaining a proper sealing environment is critical in any robotic application, especially where fluid power or lubrication is involved. It's important to adopt a proactive approach to maintenance by replacing components like O-rings regularly, ensuring optimal performance of the robot over time.
