MRO consumables and wearing parts are the most easily ignored key factors affecting factory operation rate. Most unplanned equipment downtime is caused by aging seals, air leakage, worn bearings and failed positioning parts rather than main equipment failure. Establishing a standardized full-life-cycle management system can effectively reduce downtime and stabilize production efficiency.
MRO part failures are divided into sudden failure and gradual aging failure. Electrical and plastic parts usually fail suddenly, while rubber seals, bearings and pneumatic parts show gradual aging symptoms such as air leakage, abnormal noise and slow reset. Passive maintenance will cause serious production loss, so preventive replacement is essential for modern factory management.
Rubber seals and oil seals last 8 to 12 months in clean indoor environments, and only 3 to 5 months in high-temperature, dusty or oily conditions. Pneumatic fittings and air pipes can work stably for 1 to 1.5 years under normal pressure. Bearings and guide wheels are easily affected by dust, with a service life of 6 to 10 months in continuous operation equipment.
Establish complete file records for incoming materials, classify storage reasonably, register each requisition, replace parts according to fixed cycles, and review abnormal failures regularly. Realize full traceability of consumable use and equipment maintenance.
Standardized MRO management can reduce sudden failure rate by more than 60%, eliminate emergency shutdown loss, stabilize equipment precision and reduce product defect rate, which is an important cost reduction method for industrial enterprises.
