Why Is Lubrication Important for Ungalvanized Steel Wire Rope?
Ungalvanized steel wire rope, also known as bright steel wire rope, has no zinc coating on the wire surface. Proper lubrication is therefore important for reducing friction between wires and strands while helping protect the rope against wear and corrosion.
During manufacturing, the amount and type of grease can be adjusted according to the rope construction and its intended application. Different lubrication levels can provide different levels of surface protection and lubrication.
Four Common Lubrication Methods for Ungalvanized Wire Rope
For bright steel wire rope, Shenwei can use different lubrication levels according to customer requirements and application conditions.
A1 – Lightly Greased,Yellow Grease
A1 uses a light grease coating on the rope surface.
It is suitable when a relatively clean surface and light lubrication are required. The rope remains easier to handle while still receiving basic lubrication protection.
A2 – Standard Greased,Yellow Grease
A2 provides a standard grease coating on the strands.
Compared with A1, it provides more lubrication and protection and can be used for general industrial wire rope applications.
A3 – Heavily Greased,Yellow Grease
A3 uses heavy greasing to provide a higher level of lubrication.
This method can be considered for applications where the wire rope requires stronger lubrication and protection against friction, wear and environmental exposure.
C-Type – Special Grease,Black Asphalt Grease
C-type lubrication uses black asphalt grease or special grease for elevator wire rope, depending on the rope specification and application.
For elevator wire rope, the lubricant should be selected according to the rope manufacturer's requirements and the elevator system's operating conditions.
How to Choose the Right Lubrication Level?
The appropriate lubrication method depends on several factors, including:
Wire rope construction
Application and working environment
Required surface condition
Operating load and bending frequency
Exposure to moisture and contaminants
Customer or equipment requirements
In practice, lubrication should provide an even, adherent coating without excessive grease accumulation. Industry guidance also notes that excessive lubricant can attract contaminants or create operational problems, while insufficient lubrication can increase friction, wear and corrosion risk.
Conclusion
Lubrication is an important part of the manufacturing and service performance of ungalvanized steel wire rope. A1, A2 and A3 provide different levels of greasing, while C-type lubrication can be used for specific requirements such as elevator wire rope.
Choosing the right lubricant and application level helps balance lubrication, corrosion protection, cleanliness and application requirements.
Nantong Shenwei can provide ungalvanized steel wire rope with customized lubrication according to rope construction, application and customer requirements.
