The mixture of PTFE and fibers with a thickness of 0.01‑0.03 mm can form a favorable transfer film to protect the mating shaft and endow the bearing with self‑lubricating performance.
Copper powder layer: 0.20‑0.35 mm. It features high load‑bearing capacity and wear resistance. Its good thermal conductivity dissipates heat generated during bearing operation in a timely manner. The composite material penetrates into the gaps between copper powder particles to improve bonding strength.
Low‑carbon steel, delivers good load‑bearing performance and heat transfer function.
Copper‑tin electroplated layer: 0.002 mm for enhanced corrosion resistance.
