Wear results from thermal cycling, abrasive aluminum or zinc alloys, misalignment, insufficient lubrication, or material fatigue at high temperatures (200-400°C).
Regular inspection for scoring or bending, proper lubrication with high-temperature grease, alignment checks, and timely replacement of worn pins prevent downtime.
