        "text": "Rollers on a sliding glass door can wear out due to several factors, primarily constant use, accumulation of dirt and grit, and the weight of the door itself. Over time, the materials (often nylon or steel) can degrade from friction, developing flat spots or becoming brittle. Environmental factors like moisture and temperature fluctuations can also accelerate wear. When rollers wear out, they impede smooth movement, leading to sticking.",
