What is a wire rope lubricant?

Wire ropes are an integral part of many machines and structures. Usually, they are made from good-quality carbon for strength, versatility, and resilience and are composed of continuous strands wound around a central core.

Of significance, like all other products for industrial applications, wire ropes need maintenance to last longer and function optimally. As such, lubricating wire ropes properly can safely extend their operation life regardless of its applications.

This post will in-depthly discuss wire rope lubricants to help you understand what it is.

Wire rope lubricant explained.

At its core, a wire rope lubricant is a high-performance lubricant that is applied on wire ropes to protect the outer strands of the wire rope from corrosion, ensure optimum performance and service life. The lubricants come in two types: penetrating and coating, all suited for different applications.

In comparison, coating lubricants protect the outside of the cable from corrosion and rust, while penetrating lubricants contain a solvent that carries the lubricant onto the central core. The solvent then evaporates, leaving a film that lubricates every strand.

Most wire rope manufacturers usually lubricate their ropes. However, this protective layer doesn’t last throughout the rope’s lifetime. As such, they need to be relubricated with the right lubricant.

The best lubricant should infiltrate between cables and strands, adhere excellently to stay, and resist oxidation.


Capable of minimizing corrosion, protecting and preserving a wire core and strands, and extending its lifetime, wire rope lubricants are incredibly useful. Considering that most wire ropes fail from the inside, it is of utmost importance to ensure that the center core receives sufficient lubricants. All in all, remember that the best lubricant for a certain wire rope will depend on its application and design.
