How to extend the life of a roller drive chain: storage, installation, and operation

To ensure your roller drive chain operates flawlessly and lasts as long as possible, it's essential not only to install it correctly but also store it properly an operate it smartly. Improper handling can lead to premature wear, reduced efficiency and damage to the mechanism.

Beltimport specialists have prepared key recommendations to help maintain the reliability and durability of chains throughout every stage of their use.

Storage

• Storage conditions: Chains should be stored in dry, clean environments, protected from direct sunlight and aggressive chemicals. High humidity can cause corrosion, so it’s essential to maintain humidity levels within the manufacturer’s recommended range.
• Positioning: Store chains on racks or shelves to avoid direct contact with the floor. This helps prevent dust and dirt accumulation on or inside chain components.
• Corrosion protection: For long-term storage, chains should be coated with protective grease or an anti-corrosion compound that forms a barrier against moisture and dust. Manufacturers usually apply this coating at the factory. After thoroughly lubrication of all roller chain gaps, the chain should be wrapped in oiled paper before storage.

Installation

• Pre-installation inspection: Carefully inspect the chain for any damage or defects that may have occurred during transportation or storage before mounting it on equipment.
• Alignment: make sure that the drive and driven sprocket axes are precisely aligned with each other. Missagliment can lead to uneven wear of the chain components and sprocket teeth.
• Chain tension: Excessive tension can cause accelerated wear and added stress on the chain elements, while too little tension may lead to sagging and chain slippage. Follow the chain manufacturer’s or OEM’s instructions regarding optimal tension.
• Lubrication: Chains should be lubricated either with operating lubricant or special anti-corrosion grease. In the latter case, the chain must be cleaned of pre-lubricating coating before operation and properly lubricated with a working lubricant to ensure smooth drive operation and reduced component wear.

Operation

• Cleaning: Regularly clean the chain from dust, dirt, and other contaminants. Use appropriate cleaning agents and avoid exposing chain components to aggressive chemicals.
• Wear inspection: check the chain for signs of elongation, cracks or corrosion. Timely replacement of worn components can prevent equipment malfunctions and downtime.
• Safety: Install guards or protective covers around the chain and sprockets to prevent accidental contact and avoid potential injuries.
• Regular Lubrication: Maintain proper lubrication level throughout the entire operating period. Use lubricants recommended by the manufacturer and follow the specified lubrication intervals.

Following these recommendations will ensure long-lasting and uninterrupted performance of your roller drive chains, minimizing the risk of failures and maximizing equipment efficiency.
