8 circumstances when dry film lubricants should be implemented
February 23, 2017
What are dry lubricants?
Dry film lubricants, also known as solid film lubricants, are specifically designed to reduce friction between two surfaces moving against each other. The coating provides corrosion resistance while preventing galling and seizing between moving surfaces. Dry film lubricants are the ideal option when permanent lubrication is necessary.
What are the benefits of dry film lubricants?
One of the biggest advantages is that dry film lubricants eliminate the need for oil and or grease. This provides a much cleaner option as oil and grease are well known for collecting dirt and debris. Also, this provides permanent lubrication at increased capacity for loads and pressure in comparison to oils and grease.
What happens if dry film lubricants are not used properly?
When surfaces are not treated properly prior to the coating application the coating may not adhere, losing some of the lubricating benefits. Some dry film lubricants offer greater chemical resistance than others. Therefore it is important to ensure the accurate dry film lubricant is utilized for each application.
8 Circumstances When Dry Film Lubricants Should Be Implemented
- Metals exposed to corrosive atmospheres.
- The metal parts that will be stored for a long period.
- Metals that will be rarely lubricated once they depart the factory and permanent lubrication is desired.
- When operating pressures exceed the load-bearing capacities of ordinary oils or greases.
- Where parts may be subjected to frequent disassembly.
- When “clean operation” if preferred.
- Where a protective coating and sacrificial break-in lubricant is necessary.
- When fretting and galling is problem. (example; splines, universal joints and keyed bearings.)
