Domain: technology (Hardware Troubleshooting and Maintenance)
Problem: I received these photos of a bearing from a customer who noticed some surface distress on their equipment. Based on the distinct patterns visible in these images, could you identify the specific types of wear present? I also need to understand how the combined effect of these two types of damage impacts the structural rigidity of the system
Answer: Micro-vibration and adhesive wear; they degrade preload and contact stiffness leading to a collapse in system rigidity.
