A steel-backed (Polytetrafluoroethylene) self-lubricating plain bearing is a precision-engineered component that combines the strength and durability of steel with the excellent lubrication and wear resistance of . This composite design provides an ideal solution for applications requiring high performance and long-lasting reliability.
The steel backing provides the bearing with a rigid and sturdy base, enabling it to withstand heavy loads and impact forces. Meanwhile, the layer impregnated or bonded to the steel backing offers exceptional lubrication and wear resistance. is known for its low coefficient of friction and ability to form a lubricant film, even under high-speed and high-load conditions.
The self-lubricating properties of these bearings mean that external lubricants are not required. The layer can self-lubricate by transferring minute amounts of its material to the mating surface, creating a smooth and continuous lubricant film. This significantly reduces friction and wear, extending the bearing's lifespan and reducing maintenance costs.
Steel-backed self-lubricating plain bearings are commonly used in a wide range of applications, including automotive, aerospace, and industrial machinery. They are particularly suitable for applications where lubrication is limited or not feasible, such as in high-temperature or vacuum environments.
Overall, steel-backed self-lubricating plain bearings offer an outstanding combination of strength, durability, and self-lubrication capabilities, making them a reliable choice for demanding applications requiring low friction and long-lasting performance.

Suitable for dry running with a low coefficient of friction, low wear rate, good sliding characteristics, the transfer film created will protect the mating metal surface. Suitable for rotary and oscillating movement, high chemical resistance, lower absorption of water and reduced swelling. Also performs well with lubrication.
1. /Fibre mixture thickness 0.01~0.03mm, provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides Max. thermal conductivity away from the bearing surface, also serves as a reservoir for the -Fibre mixture.
3. Low-carbon steel, gives exceptionally high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm, provides good corrosion resistance.
