Oil-Air Lubrication vs Grease Lubrication: Which Is Better for Steel Plants?
Release time:
2022-03-10
Choosing the right lubrication system is essential for improving equipment reliability and reducing maintenance costs in steel plants.
The two most common solutions are grease lubrication and oil-air lubrication.
Grease lubrication is widely used because of its simple structure and relatively low initial investment. However, in high-speed or high-temperature applications, grease can harden, oxidize, or fail to provide sufficient cooling.
Oil-air lubrication offers a more advanced solution.
By delivering small quantities of lubricant through compressed air, the system continuously supplies fresh oil while simultaneously cooling bearings.
Compared with grease lubrication, oil-air lubrication provides:
- Lower lubricant consumption
- Better bearing cooling
- Continuous fresh lubrication
- Reduced contamination
- Longer bearing service life
- Higher equipment reliability
Typical applications include:
- Wire rod mills
- Bar mills
- Hot strip mills
- Continuous casting machines
- Roller tables
- Roller conveyors
Although the initial investment may be higher than conventional grease lubrication, most steel plants recover the investment through reduced maintenance costs and increased production efficiency.
For demanding industrial environments, oil-air lubrication has become the preferred lubrication technology.
