Wire rope lubrication serves two main functions: reducing friction between strands and lubricating the core, and providing corrosion protection. There are two types of lubricants - penetrating lubricants which carry lubricant into the core, and coating lubricants which seal the outside. Proper lubrication is important to prevent failure from inside the rope. Benefits include extending service life by reducing abrasive wear. A good penetrating lubricant penetrates between wires, is adhesive, has high load capacity, and protects against corrosion. Molykote products include greases and sprays suitable for wire rope lubrication.
