Ring Lubrication and Anti-Friction Coatings
topic
Initial ring lubrication (oiling) is applied after ring installation or cleaning to reduce running-in wear. Automatic lubrication systems apply oil at intervals of 200–500 running hours. Lubricant type: mineral oil, SAE 5–10 viscosity, applied at 0.01–0.05 ml per ring per application. Over-lubrication causes yarn contamination (oil spots visible after dyeing); under-lubrication causes premature ring and traveller wear. Self-lubricating ring coatings (PTFE-impregnated) reduce maintenance frequency.
Role
Ring lubrication management prevents two opposing quality and cost problems: oil contamination faults (rejectable fabric) and premature wear (productivity loss). Systematic lubrication scheduling with correct oil quantities is a quality and maintenance discipline that is often neglected, yet directly responsible for significant defect costs in industrial production.
