The lubrication and maintenance of roller conveyors directly affect equipment lifespan, operating efficiency, and failure rate. Different operating conditions (such as dust, humidity, and temperature) significantly impact lubrication requirements. The following provides actionable guidance on lubrication cycles and maintenance strategies for six typical operating conditions, supported by practical examples.
General Principles of Lubrication and Maintenance
Lubricant Selection:
Mineral grease: For general operating conditions, highly economical (e.g., Shell Gadus S2 V220).
Synthetic grease: For extreme temperatures/high loads (e.g., Mobil SHC 220, temperature resistance -30℃~150℃).
Food-grade lubricant: NSF H1 certified (e.g., Kluber Isoflex NBU 15).
Lubrication Quantity Standard: 1/3 to 1/2 of the bearing cavity volume; excessive lubrication can lead to overheating.
Safe Operation: Operate only after the machine is stopped and the power is off, avoiding contact with moving parts.
Maintenance Records and Optimization Suggestions
Digital Management:
Use a CMMS system (e.g., Fiix, UpKeep) to record lubrication time, quantity, and anomalies.
Use AI based on historical data to predict the next maintenance time (error < ±5%).
Failure Analysis:
Regularly sample used grease and test for iron chip content (>0.5% requires investigation of the wear source).
Monitor bearing temperature with an infrared thermal imager (abnormal temperature rise >15℃ requires immediate inspection).
