Industry Knowledge

Solid-lubricant oilless bushings, also known as self-lubricating bushings, are a type of plain bearing that does not require external lubrication to operate. These bushings are made of a porous metal, such as bronze or iron, that is impregnated with a solid lubricant, such as graphite, molybdenum disulfide, or PTFE (polytetrafluoroethylene).
The solid lubricant in the bushing provides continuous lubrication and reduces friction and wear, making the bushings ideal for high-load, low-speed, and oscillating motion applications. The porous metal structure of the bushing provides excellent wear resistance and thermal conductivity.
Solid-lubricant oilless bushings are commonly used in applications such as food processing equipment, medical devices, and automotive applications. They offer several advantages, including reduced maintenance and downtime, longer service life, and improved performance in harsh and dirty environments. They can also operate in a wide range of temperatures and are resistant to corrosion.
These bushings are available in various sizes and dimensions to suit different applications and can be customized to fit specific requirements. However, they can be more expensive than other types of plain bearings due to their advanced material composition and manufacturing process.
