I. Visual and Craftsmanship Inspection‌
‌‌Surface and Welding Quality‌‌

• Observe whether the roller surface is smooth and even, free from bubbles, sand holes, cracks, or significant rust marks. Surface defects can easily lead to stress concentration and premature failure.
• Inspect welded areas: Welds must be uniform and full, without incomplete penetration, lack of fusion, or weld spatter. Poor-quality welding can easily cause structural fractures.

‌‌Dimensional Accuracy Verification‌‌

• Use calipers to measure key dimensions such as roller diameter and length. Deviation should be kept within permissible tolerances (typically diameter tolerance ≤ ±0.5mm, length tolerance ≤ ±1mm). Incorrect dimensions may cause installation difficulties or eccentric wear during operation.
