What does galling of chain means?

Galling of chain refers to a type of wear or damage that occurs on the surfaces of chain links, often due to metal-to-metal contact under high loads and inadequate lubrication. It results in the formation of rough, raised areas or grooves on the chain surfaces, which can lead to increased friction, reduced efficiency, and ultimately chain failure. This phenomenon is particularly common in applications involving heavy-duty machinery or equipment, where chains are subjected to significant stress. Preventive measures include proper lubrication and regular maintenance to minimize wear.
